Problem 114

Title: Simulating the Dynamics of Physical Systems with Physics-Informed Neural Networks
Problem description: The problem of choosing the optimal model for predicting the dynamics of a physical system is being solved. Under the dynamics of the system is understood the change in time of the parameters of the system. Neural networks do not have a priori knowledge about the system being modeled, which does not allow obtaining optimal parameters that take into account physical laws. The Lagrangian neural network takes into account the law of conservation of energy when modeling dynamics. In this paper, a Noetherian Agrangian neural network is proposed that takes into account the laws of conservation of momentum and angular momentum in addition to the law of conservation of energy. It is shown that for this problem the Noetherian Lagrangian neural network is optimal among the fully connected neural network model, the neural network with long-term short-term memory and the Lagrangian neural network. The simulation comparison was carried out on artificially generated data for the double pendulum system, which is the simplest chaotic system. The results of the experiments confirm the hypothesis that the introduction of a priori knowledge about the physics of the system improves the quality of the model.
Problem description:Generate a set of convolutions from the available data and choose the best one using order and dimensionality reduction techniques.

Data: CIFAR-10. It is assumed that the teacher has a structure open for analysis with a large number of layers.
Literature: Hinton's original work on distillation, work by Andrei Grabovoi, work by Maria Gorpinich

Solution: As in paragraph 2, only in layers. Building the path of least cost over neurons. We consider the covariance matrices of each neuron of each layer for the teacher and for the student. We propose an error function that includes the cost of the least cost path. We propose a way to construct the path of the least cost. The main idea: the transfer goes through pairs of neurons and the most similar distributions (expectation and covariance matrix) from teacher to student.
Novelty: The proposed transfer significantly reduces complexity without loss of accuracy and solves the problem of interchangeability of neurons by identifying them.

The sampling procedure itself consists of two steps: generating a new structure and rejecting this structure if it does not satisfy the optimality criterion. Required on 'pendulum' type data - accelerometer, myogram, pulse wave - to choose the optimal model.

Problem 117

Title: Search for dependencies of biomechanical systems (do people dance in pairs or independently?) and (Method of Convergence Cross-Mpping, Takens theorem)
Problem description: When forecasting complex time series that depend on exogenous factors and have multiple periodicity, it is required to solve the problem of identifying related pairs of series. It is assumed that the addition of these series to the model improves the quality of the forecast. In this paper, to detect relationships between time series, it is proposed to use the convergent cross-mapping method. With this approach, two time series are connected if their trajectory subspaces exist, the projections onto which are connected. In turn, the projections of series onto trajectory subspaces are related if the neighborhood of the phase trajectory of one series is mapped to the neighborhood of the phase trajectory of another series. The problem of finding trajectory subspaces that reveal the connection of series is set.

Problem 118

Title: Continuous time when building a BCI neural interface
Problem description: In signal decoding The problems, data is represented as multidimensional time series. When solving problems, a discrete representation of time is used. However, recent work on neural ordinary differential equations illustrates the ability to work with the hidden state of recurrent neural networks, as with solutions to differential equations. This allows us to consider time series as continuous in time.

Problem 119

Title: Analysis of the dynamics of multiple learning
Problem description: Consider a supervised multiple learning problems in which the training set is not fixed but is updated depending on the predictions of the trained model on the test set. For the process of multiple training, prediction and updating of the sample, we build a mathematical model and study the properties of this process based on the constructed model. Let f(x) be a feature distribution density function, G be an algorithm for training the model, generating predictions on the test set and mixing predictions into the training set, as a result of which the feature distribution changes. Let the space of non-negative smooth functions F(x) be given, whose integral on R^n is equal to one. f_{t+1}(x) = G(f_{t})(x), where G(f) is the evolution operator on the space of these functions F and the initial function f_0(x) is known. In general, G can be an arbitrary operator, not necessarily smooth and/or continuous. Question 0. Find conditions on the operator G under which the image of G lies in the same class of distribution density functions F. In particular, should G be bounded, the operator norm ||G|| <= 1, so that the image of G(f) \in F is also a distribution density function for any f from F? Does there exist a unit in the space F with respect to the operator G, and what will be the identity function f in such F? Question 1. Under what conditions will there be a t_0 on G such that for all t > t_0 the tail of the sequence {f} will be bounded? Question 2. Under what conditions will the operator G have a fixed point? Data In a computational experiment, it is proposed to check the significance of the restriction / the significance of the conditions under which the answer to questions 0-2 is obtained. For example, for a problem of linear regression and/or regression with a multilevel fully connected neural network with different proportions of predictions mixed into the training set on synthetic data sets.

Problem 122

Problem description: Reducing the dimension of space in a generative modeling problem using reversible models.
Problem description: An example of a generative modeling problem is image generation. Some kinds of new models, such as normalization flows or diffusion models, define reversible transformations. But at the same time they work in a space of very high dimensions. It is proposed to combine 2 approaches: dimensionality reduction and generative modeling.

It is proposed to develop this method and explore various ways to set the functional for sampling
Data: Any image dataset (MNIST/CIFAR10).
Novelty: By speeding up diffusion models, they will become even more popular and easier to use.

Problem 125

Title: Influence of the lockdown on the dynamics of the spread of the epidemic
Problem description: The introduction of a lockdown is considered an effective measure to combat the epidemic. However, contrary to intuition, it turned out that under certain conditions, a lockdown can lead to an increase in the epidemic. This effect is absent for the classical models of the spread of the epidemic “on average”, but was revealed when modeling the epidemic on the contact graph. The problem is to find formulaic and quantitative relationships between the parameters under which the lockdown can lead to an increase in the epidemic. It is necessary both to identify such relationships in the SEIRS/SEIR/SIS/etc models based on the SEIRS+ epidemiological distribution framework (and its modifications), and to theoretically substantiate the relationships obtained from specific implementations of the epidemia.
Data: The problem involves working with model and synthetic data: there are ready-made data, and it is also possible to generate new ones in the process of solving the problem. This The problem belongs to unsupervised learning, since the implementation of the epidemic on the contact graph has a high proportion of random events, and therefore requires analysis on average over many synthetically generated implementations of the epidemic

Data: CIFAR10, CIFAR100
Literature: variational inference for neural networks, hypernets, similar work tailored to change the model depending on a predetermined complexity
Base algorithm: Retrain the model directly.
Solution: The proposed method is to represent a deep learning model as a hypernet (a network that generates the parameters of another network) using a Bayesian approach. Probabilistic assumptions about the parameters of deep learning models are introduced, and a variational lower estimate of the Bayesian validity of the model is maximized. The variation estimate is considered as a conditional value, depending on the information about the problem data.
Novelty: The proposed method allows you to generate models in one-shot mode (practically without retraining) for the required The problem, which significantly reduces the cost of optimization and retraining.

Problem 131

Title: Iterative improvement of the topic model with user feedback
Problem description: Topic modeling is widely used in socio-humanitarian research to understand the thematic structure of large text collections. A typical use case would involve the user rating topics as relevant, irrelevant, and junk. If the number of garbage topics is too large, then the user tries to build another model. The problem is to use custom markup for each such rebuild in such a way that relevant topics are preserved, new relevant ones stand out from irrelevant and garbage topics if possible, and there are as few garbage topics as possible.
Data: Any collection of natural language texts about which the thematic structure is known (about how many topics, how many documents on different topics) is suitable as data. For example, you can take a collection of Lenta news, a Wikipedia dump, posts from Habrahabr, 20 Newsgroups, Reuters, articles from PostNauka. The subject of the collection should be of interest to the researcher himself, so that there is motivation to evaluate topics manually.

Solution: Using the BigARTM theme modeling library. Use of smoothing and decorrelation regularizers. Development of methods of initialization when rebuilding thematic models. Finding a ready-made tool or developing a simple, fast, convenient way to view and markup topics.
Novelty: The problem of non-uniqueness and instability of models still does not have a final solution in probabilistic thematic modeling. The proposed study is an important step towards building models with the maximum number of interpretable topics that are meaningfully useful from the point of view of humanitarian research.

The object of the training set is a sequence of references to articles from the bibliography mentioned in the review sections. For each document there is a set of metadata - year of publication, journal, number of citations, number of citations of the author, etc. Also, there is an abstract and, possibly, the full text of the article. - Kendall's rank correlation coefficient is used as a metric.

Problem 133

Title: Diffusion models in the problem of generating the structure of a molecule with optimal energy
Problem description: For an organic small molecule (the number of atoms is less than 100), knowing only the topology of the molecular graph is not enough to obtain the spatial structure. A molecule can have many possible configurations (conformers), each of which corresponds to a local minimum of the potential. In practice, of greatest interest are the most stable conformers, which have the lowest energy. Recent studies show the success of the application of diffusion models for the generation of molecular structures. This approach shows advanced results in the problem of generating molecules and their conformers for a small number of heavy atoms (QM9 dataset up to 9 heavy atoms in a molecule), as well as in assessing the binding of a molecule and a protein. It is proposed to build a model for the generation of conformers with minimum energy for larger molecules.

Problem 134

Title: Combining distillation of models and data
Problem description: Knowledge distillation is the transfer of knowledge from a more meaningful representation to a compact, concise representation. There are two kinds of knowledge distillation. The first is the distillation of models. In this case, the large model transfers knowledge (distilled) to the small model. The second is data distillation. In this case, a minimum data set is created, on which, after training the model, it achieves a quality comparable to training on a full sample. At the moment, there is no solution that can implement simultaneous distillation of model and knowledge. Therefore, the goal of The problem is to propose a basic solution for model distillation and compare with approaches to model distillation and data distillation.

For adaptation, it is proposed to build a new model of greater complexity with further transfer of information from a simple model to it. When transferring information, it is necessary to take into account not only the quality of the forecast on the original sample, but also the adaptability of the new model to the new sample and the robustness of the solution obtained.
Data: MNIST handwritten digit sampling, CIFAR-10 image sampling
Literature: Original distillation problem statement: Hinton G. et al. Distilling the knowledge in a neural network //arXiv preprint arXiv:1503.02531

Data: MNIST handwritten digit sampling, CIFAR-10 image sampling
Literature:
1. Exact and Consistent Interpretation for Piecewise Linear Neural Networks: A Closed Form Solution
2. "Why Should I Trust You?": Explaining the Predictions of Any Classifier
Base algorithm: The LIME(1) algorithm interprets the model by local approximation
Solution: A solution based on the method described in (2) is proposed. In this paper, a generalization of the multilayer perzpetron model with a piecewise linear activation function was proposed. Such an activation function allows us to consider the classifier for each sample object as a locally linear one, without using approximation. It is proposed to generalize the proposed approach to the main nonlinear functions used in convolutional neural networks: convolution, pooling and normalization functions.
Novelty: is to obtain a new class of neural models that lend themselves to good interpretation.

Problem 93.2022

Title: Estimating the risk of forest fires using machine learning methods.
Problem description: Wildfire risk prediction based on climate variables (water/air temperature, atmospheric pressure) since 1991. Forecasting is carried out (a) in the short-term range (2-5 years; stationary time series) and (b) in the long-term range (up to 50 years; non-stationary time series). A feature of forecasting in the long range is the (probable) significant change in the behavior of climate variables (CMIP5 scenarios). The key features of problem (1) are the need for a sufficiently accurate prediction of extreme risk values (maximum values of the time series), while the algorithm can make a significant number of errors in the region of small values of the series. (2) the spatial data structure of the series.
Data:
1. Google Earth Data - data on climate variables and landscape available via API (there is a jupyter notebook through which you can download data locally)
2. CMIP5 climate scenarios (there is a jupyter notebook through which you can download data locally)
3. Wildfire Risk Database
4. Severe Weather Dataset
Literature:
Base algorithm: (1) method from article 1, (2). ST-LSTM
Solution: is proposed to solve the problem in two steps. At the first step, Algorithm 1 (with the addition of a spatial component) restores (averaged over a certain range) the behavior of the time series. Next, the discrepancy between the values of the series and the model is analyzed. Based on this, the noise distribution is restored and a probabilistic model is built to achieve a certain level of risk in a given territory in the required time range.
Novelty: (geo)-spatial time series prediction is an open area with great potential for theoretical and practical work. In particular, fire risk assessment is necessary for (1) predicting the probability of accidents (electric power industry, gas transport complex); (2) prioritization of fire prevention measures by region; (3) assessing the financial risks of companies operating in the region.

Problem 95.2022

Title: Identification the transmission rate and time-dependent noise for the stochastic SIER disease model with vital rates (Time-dependent parameter identification for a stochastic epidemic model)
Problem description: The problem is set to find the optimal time-dependent parameters for the known stochastic SIER disease propagation model. The optimal parameters are the parameters of the stochastic equation, under which the sample of the rate of spread of the virus in a limited population, when using comparison with the optimal sample. It is proposed to use the adaptive generalized method of moments with local delay (LLGMM) based on the generalized method of moments (GMM).
Data: Hopkins Institution's Coronavirus Increasing Data is available from various sources. You can also download the data yourself from the link.
Literature:
1. Anna Mummert, Olusegun M. Otunuga Parameter identification for a stochastic SEIRS epidemic model: case study influenza PDF
2. David M. Drukker Understanding the generalized method of moments (GMM): A simple example LINK
Keywords: Compartment disease model, Stochastic disease model, Local lagged adapted generalized method of moments, Time-dependent transmission rate
Base algorithm: there are several different options on the Internet, for example, the article B.Tseytlin Actually forecasting COVID-19 LINK, the current program does not give good convergence, because it always uses a fixed number of points for prediction
Novelty: a new LLGMM method of moments that increases the accuracy of prediction& The basic idea of the method of moments is to use in moment conditions (moment functions or simply moments) instead of mathematical expectations, sample means, which, according to the law of large numbers under sufficiently weak conditions, should converges asymptotically to the mathematical expectations. Since the number of conditions for moments in the general case is greater than the number of estimated parameters, this system of conditions does not have a unique solution. The generalized method of moments suggests a situation where it is possible to obtain more conditions for moments than estimated parameters. The method constructs moment conditions (moment functions), also called orthogonality conditions, in a more general form as some function of model parameters and data. The parameters are estimated by minimizing a certain positive quadratic form from the sample means for the moments (moment functions). The quadratic form is in an iterative process with the required accuracy. If the model contains more than one parameter (this is our case) to be identified, then the second and higher moments are used to construct moment conditions. LLGMM defines time-dependent parameters by using a limited number of "points" in a data time series to form moment conditions, rather than the entire series. So the method is late. In addition, the number of time series elements used varies for each estimate over time. Thus, the method is local and adaptive.

Problem 96.2022

Title: Impact of the lockdown on the dynamics of the epidemic
Problem description: The introduction of a lockdown is considered an effective measure to combat the epidemic. However, contrary to intuition, it turned out that under certain conditions, a lockdown can lead to an increase in the epidemic. This effect is absent for classical models “on average”, but was revealed when modeling the spread of the epidemic, taking into account the contact graph. The problem is to find formulaic and quantitative relationships between the parameters under which the lockdown can lead to an increase in the epidemic.
Data: Real data on the spread of the epidemic on contact graphs, especially considering the need for scenario analysis, is not available. The problem involves working with model and synthetic data: there are ready-made data, and it is also assumed that new ones can be generated in the process of solving the problem.

Problem 102.2022

Title: Graph neural networks in the problem of regression of pairs of graphs
Problem description: Considered The problem regression on a pair of graphs. In a pair, each vertex of one graph corresponds to a vertex of the second graph. It is required to establish the optimal architecture of the graph neural network, taking into account the given order specified on the vertices.
Data: It is suggested to use chemical reaction datasets github. For a given dataset, a pair of graphs is specified in a natural way. These are graphs of molecules of initial substances and products of a chemical reaction.
Literature:
Base algorithm: The graph relationship is set at the level of graph embeddings. That is, a separate embedding vector is built for each graph, and then the vector data is concatenated. In this case, information about the correspondence of vertices in graphs is not explicitly used.
Novelty: On the example of the architecture of a graph neural network with fixed hyperparameters, from a theoretical and practical point of view, to study ways to add information about the relationship of graphs to a graph neural network.

Problem 103.2022

Requirement: Fluent English to collaborate, Python and PyTorch (medium level and higher), Git, Bash, Background in computational biology is a plus
Introduction: See full description here. Proteins are involved in several biological reactions by means of interactions with other proteins or with other molecules such as nucleic acids, carbohydrates, and ligands. Among these interaction types, protein–protein interactions (PPIs) are considered to be one of the key factors as they are involved in most of the cellular processes [1]. The binding of two proteins can be viewed as a reversible and rapid process in an equilibrium that is governed by the law of mass action. Binding affinity is the strength of the interaction between two (or more than two) molecules that bind reversibly (interact). It is translated into physico-chemical terms in the dissociation constant Kd, the latter being the concentration of free protein at which half of all binding sites of the second protein type are occupied [2].
Objectives: Three main objectives of this work can be formulated as follows: 1. Refine PDBbind [12] data and a standard binding affinity dataset [3], and compile a novel benchmark of PPIs with known binding affinity values. 2. Employ graph-learning toolset to predict binding affinities of PPIs from the new dataset. 3. Benchmark the resulting method against existing state-of-the-art approaches
Data & Metrics: In this work, we will operate on experimentally-observed three-dimensional structures of protein-protein complexes annotated with the binding affinity values. Two main sources of data are the following:
PDBbind dataset [12] that includes around 2k PPIs
Standard dataset introduced in [3] that includes 144 PPIs As main regression metrics, we suggest to consider Mean Squared Error (MSE), Mean Absolute Error (MAE) and Pearson correlation.
Novelty: To the best of our knowledge, geometric deep learning methods have never been applied to the protein-protein binding affinity prediction problem so far.

Problem 109.2022

Title: Continuous time when building a BCI neural interface
Problem description: In Signal Decoding The problems, data is represented as multivariate time series. When solving problems, a discrete representation is used time. However, recent work on neural ordinary differential equations illustrates the ability to work with the hidden state of recurrent neural networks, as with solutions to differential equations. This allows us to consider time series as continuous in time.
Data: For classification:
1. dataset P300, according to which the article was written
2. dataset DEAPdataset similar to it in the format of records.
3. Definition of emotions.
4. Same SEED emotion classification
5. Not EEG, but accelerometer data with activity/position classification
6. For regression, you can take the same neurotycho, if you want to complicate life somewhat with respect to classification problems.

Problem 104.2022

Title: (Clarification awaited) Cross-language duplicate search
Problem description: The problem of cross-language search for text plagiarism is set. The search for duplicates of the original text is carried out among texts in 100 different languages.
Data:
1. A selection of scientific articles from the scientific electronic library eLIBRARY.ru, as well as articles from the Wikipedia online encyclopedia, is used as a training sample.
2. The State Rubricator of Scientific and Technical Information (SRSTI), the Universal Decimal Classifier (UDC) are considered as scientific rubricators.
3. The following are used as search quality metrics:
4. average frequency - the frequency, averaged over the control languages, with which the query document falls into the top 10% of documents among which the search is carried out
5. average percentage - the percentage of documents, averaged over the control languages, that are in the top 10% of translation documents that have the same scientific heading as the query document
Literature: Vorontsov K. V. Probabilistic thematic modeling: review of models and additive regularization PDF
Base algorithm:
1. Hierarchical topic models
2. Topic models with one-pass document vectorization
Solution: To solve the search problem, a multimodal thematic model was built. 100 languages were used as modalities, as well as scientific headings, which included articles from the training data. A series of experiments was carried out to improve search quality metrics, including: selection of the optimal tokenization method, addition of regularizers, selection of thematic vector comparison functions, ranking functions, etc.
Novelty: Most systems for finding documents in large collections are based on vectorization of the documents in the collection and the search document in one way or another. The latest ways to vectorize documents are usually limited to one language. In this case, the problem arises of creating a uniform system for obtaining vector embeddings of a multilingual collection of documents. The proposed approach makes it possible to train a topic model that encodes information about the distribution of words in a text, regardless of their language affiliation. Also, the solution is subject to restrictions on the size of the model and training time, due to the possibility of practical use of the described model.

Problem 52.2022

Title: (pending clarification) Predicting the quality of protein models using spherical convolutions on 3D graphs.
Problem description: The purpose of this work is to create and study a new convolution operation on three-dimensional graphs within the framework of solving the problem of assessing the quality of three-dimensional protein models (The problem regression on graph nodes).
Data: Models generated by CASP contestants are used.
Literature:
Base algorithm: As a base algorithm, we will use a neural network based on the graph convolution method, which is generally described in [4].
Solution: The presence of a peptide chain in proteins allows you to uniquely enter local coordinate systems for all graph nodes, which makes it possible to create and apply spherical filters regardless of the graph topology.
Novelty: In general, graphs are irregular structures, and in many Graph Learning The problems, sample objects do not have a single topology. Therefore, the existing operations of convolutions on graphs are greatly simplified or do not generalize to different topologies. In this paper, we propose to consider a new method for constructing a convolution operation on three-dimensional graphs, for which it is possible to uniquely choose local coordinate systems associated with each node.

Problem 74.2021

Title: Existence conditions for hidden feedback loops in recommender systems
Problem description: In recommender systems, the effect of artificially inadvertently limiting the user's choice due to the adaptation of the model to his preferences (echo chamber / filter bubble) is known. The effect is a special case of hidden feedback loops. (see - Analysis H.F.L.). It is expressed in the fact that by recommending the same objects of interest to the user, the algorithm maximizes the quality of its work. The problem is a) lack of variety b) saturation / volatility of the user's interests.
Problem description:It is clear that the algorithm does not know the interests of the user and the user is not always honest in his choice. Under what conditions, what properties of the learning algorithm and dishonesty (deviation of the user's choice from his interests) will the indicated effect be observed? Clarification. The recommendation algorithm gives the user a_t objects to choose from. The user selects one of them c_t from Bernoulli from the model of interest mu(a_t) . Based on the user's choice, the algorithm changes its internal state w_t and gives the next set of objects to the user. On an infinite horizon, you need to maximize the total reward sum c_t. Find the conditions for the existence of an unlimited growth of user interest in the proposed objects in a recommender system with the Thomson Sampling (TS) MAB algorithm under conditions of noisy user choice c_t. Without noise, it is known that there is always unlimited growth (in the model) [1].
Data: are created as part of the experiment (simulation model) by analogy with the article [1], external data is not required.

Base algorithm: The initial mathematical model of the phenomenon under study is described in the article [1]. The method of experimental research is in the article [2]. The base source code is available at [3]
Solution: It is necessary to derive conditions for the existence of positive feedback for the Thomson Sampling Multi-armed Bandit algorithm based on the known theoretical properties of this algorithm. Then check their performance in the simulation model. For verification, a series of experiments is performed with the study of parameter ranges and the estimation of the error (variance) of the simulation. The results are compared with the previously constructed mathematical model of the effect. There is an implementation of the experiment system that can be improved for this The problem.
Novelty: The studied positive feedback effect is observed in real and model systems and is described in many publications as an undesirable phenomenon. There is his model for the limited case of the absence of noise in the user's actions, which is not implemented in practice. Under the proposed conditions, The problem has not previously been posed and not solved for recommender systems. For the regression problem, the solution is known.

Problem 77.2021

Title: Determining the phase and disorder of human movement by signals from wearable devices
Problem description: A wide class of periodic movements of a person or an animal is investigated. It is required to find the beginning and end of the movement. It is required to understand when one type of movement ends and another begins. For this, The problem of segmentation of time series is solved. The phase trajectory of one movement is constructed and its actual dimension is found. The purpose of the work is to describe a method for finding the minimum dimension of the phase space. By repetition of the phase, segment the periodic actions of a person. It is also necessary to propose a method for extracting the zero phase in a given space for a specific action. Bonus: find the discord in the phase trajectory and indicate the change in the type of movement. Bonus 2: do this for different phone positions by proposing invariant transformation models.
Data: The data consists of time series read from a three-axis accelerometer with an explicit periodic class (walking, running, walking up and down stairs, etc.). It is possible to get your own data from a mobile device, or get model data from the dataset UCI HAR

Base algorithm: The basic algorithm is described in 1 and 3 works, code here, work code 3 author.
Solution: It is proposed to consider various dimensionality reduction algorithms and compare different spaces in which the phase trajectory is constructed. Develop an algorithm for finding the minimum dimension of the phase space in which the phase trajectory has no self-intersections up to the standard deviation of the reconstructed trajectory.
Novelty: In Motrenko's article, the space dimension is equal to two. This shortcoming must be corrected. The phase trajectory must not intersect itself. And if we can distinguish one type of movement from another within one period (switched from running to a step and realized this within one and a half steps), it will be great.

Problem 78. 2021

Title: Importance Sampling for Scenario Approximation of Chance Constrained Optimization
Problem description: Optimization problems with probabilistic constraints are often encountered in engineering practice. For example, The problem of minimizing energy generation in energy networks, with (randomly fluctuating) renewable energy sources. In this case, it is necessary to comply with safety restrictions: voltages at generators and consumers, as well as currents on the lines, must be less than certain thresholds. However, even in the simplest situations, The problem cannot be resolved exactly. The best-known approach is the chance constrained optimization methods, which often give a good approximation. An alternative approach is sampling the network operation modes and solving the problem on the data set of the classification * Problem description: separating bad modes from good ones with a given error of the second kind. At the same time, for a sufficiently accurate solution, a very large amount of data is required, which often makes the problem numerically inefficient. We suggest using “importance sampling” to reduce the number of scenarios. Importance sampling consists of substituting a sample from a nominal solution, which often carries no information since all bad events are very rare, with a synthetic distribution that samples the sample in a neighborhood of bad events.
Problem statement: find the minimum of a convex function (price) under probabilistic constraints (the probability of exceeding a certain threshold for a system of linear/quadratic functions is small) and numerically show the effectiveness of sampling in this problem.
Data: Data is available in the pypower and matpower packages as csv files.

4. In addition, the authors of the problem have a draft of the article, in which you need to add a numerical part.
Base algorithm: A list of basic algorithms is provided in this lecture LINK
Solution: in numerical experiments, you need to compare the sample size requirements for standard methods (scenario approximation) and using importance sampling to obtain a solution of comparable quality (and inverse The problem, having equal sample lengths, compare the quality of the solution)
Novelty: The problem has long been known in the community and scenario approximation is one of the main methods. At the same time, importance sampling helps to significantly reduce the number of scenarios. We have recently received a number of interesting results on how to calculate optimal samplers, with their use the complexity of the problem will be significantly reduced

Title: Improving Bayesian Inference in Physics Informed Machine Learning
Problem description: Machine learning methods are currently widely used in physics, in particular, in solving turbulence problems or analyzing the stability of physical networks. At the same time, the key issue is which modes to choose for training models. A frequent choice is a sequence of points that uniformly covers the admissible set. However, often such sequences are not very informative, especially if analytical methods give a region where the system is guaranteed to be stable. The problem proposes several methods of sampling: allowing to take into account this information. Our goal is to compare them and find the one that requires the smallest sample size (empirical comparison).
Data: The experiment is proposed to be carried out on model and real data. The simulation experiment consists in analyzing the stability of (slightly non-linear) differential equations (synthetic data is self-generated). The second experiment is to analyze the stability of energy systems (data from matpower, pypower, GridDyn).

Solution: sampling methods by importance, in particular the extension of the approach (Boy, Ryi, 2014) and (Owen, Maximov, Chertkov, 2017) and their applications to ML/DL for physical problems
Novelty: in a significant reduction in sample complexity and the explicit use of existing and analytical results and learning to solve physical problems, before that ML approaches and analytical solutions were mostly parallel courses

Problem 81.2021

Title: NAS — Generation and selection of neural network architectures
Problem description: The problem of choosing the optimal neural network architecture is set as The problem of sampling the vector of structural parameters. The optimality criterion is defined in terms of the accuracy, complexity and stability of the model. The sampling procedure itself consists of two steps: generating a new structure and rejecting this structure if it does not satisfy the optimality criterion. It is proposed to explore various methods of sampling. The formulation of the problem of choosing the optimal structure is described in Potanin-1
Data: : Two separate sets are offered as data. The first one consists of one element, this is the popular MNIST dataset. Pros - is a strong and generally accepted baseline, was used as a benchmark for the WANN article, quite large (multi-class classification). The second set is a set of datasets for the regression The problem. Size varies from very small to quite large. Here is a link to the dataset and laptop to download the data data.

Base algorithm: Closest project, and its code. Actual code from consultant.
Solution: A number of experiments have already been performed, where sampling is performed by a genetic algorithm. Acceptable results have been obtained. It is proposed to analyze and improve them. Namely, to distinguish two modules: generation and deviation and compare several types of sampling. Basic - Importance sampling, desirable - Metropolis-Hastings (or even Metropolis-Langevin) sampling. Since the genetic algorithm is considered by us as a process with jumps, it is proposed to take this into account when designing the sampling procedure. The bonus of MH is that it has a Bayesian interpretation. The first level of Bayesian inference as applied to MH is described in [Informatica]. It is required either to rewrite it in terms of the distribution of structural parameters, or to describe both levels in general, moving the structural parameters to the second level (by the way, approximately the same will be in the Aduenko problem).
Novelty: Neural networks excel at The problems of computer vision, reinforcement learning, and natural language processing. One of the main goals of neural networks is to perform well The problems that are currently solved exclusively by humans, that is, natural human neural networks. Artificial neural networks still work very differently from natural neural networks. One of the main differences is that natural neural networks evolve over time, changing the strength of connections and their architecture. Artificial neural networks can adjust the strength of connections using weights, but cannot change their architecture. Therefore, The problem of choosing the optimal structures of neural networks for specific The problems seems to be an important step in the development of the capabilities of neural network models.

Title: Training with an Expert for a sample with many domains.
Problem description: The problem of approximating a multi-domain sample by a single multi-model - a mixture of Experts is considered. As data, it is supposed to use a sample that contains several domains. There is no domain label for each object. Each domain is approximated by a local model. The paper considers a two-stage The problem optimization based on the EM algorithm.
Data: Samples of reviews from the Amazon site for different types of goods are used as data. It is supposed to use a linear model as a local model, and use tf-idf vectors within each domain as an indicative description of reviews.
References:
Basic algorithm and Solution: The basic solution is presented here. The work uses the expert mixture method for the Multi-Soruce domain adaptation problem. The code for the article is available link.
Novelty: At the moment, in machine learning there are more and more The problems related to data that are taken from different sources. In this case, there are samples that consist of a large number of domains. At the moment, there is no complete theoretical justification for constructing mixtures of local models for approximating such types of samples.

Problem 17.2021

Title: BCI: Selection of consistent models for building a neural interface
Problem: When building brain-computer interface systems, simple, stable models are used. An important step in building an interface is such a model is an adequate choice of model. A wide range of models is considered: linear, simple neural networks, recurrent networks, transformers. The peculiarity of the problem is that when making a prediction, it is required to model not only the initial signal taken from the cerebral cortex, but also the target signal taken from the limbs. Thus, two models are required. In order for them to work together, a space of agreements is being built. It is proposed to explore the properties of this space and the properties of the resulting forecast (neural interface) on various pairs of models.

Problem 84.2021

Title: Trajectory Regularization of Deep Learning Model Parameters Optimization Based on Knowledge Distillation
Problem description: The problem of optimizing the parameters of a deep learning model is considered. The case is considered when the responses of a more complex model (teacher model) are available during optimization. The classical approach to solving such a problem is learning based on the responses of a complex model (knowledge distillation). Assignment of hyperparameters is made empirically based on the results of the model on delayed sampling. In this paper, we propose to consider a modification of the approach to knowledge distillation, in which the coefficient of significance of the distilling term, as well as its gradients, act as hyperparameters. Both of these groups of parameters allow you to adjust the optimization of the model parameters. To optimize hyperparameters, it is proposed to consider the optimization problem as a two-level optimization problem, where at the first level of optimization The problem of optimizing the model parameters is solved, and at the second level The problem of optimizing hyperparameters is approximately solved by the value of the loss function on the delayed sample.
Data: Sampling of CIFAR-10 images
References:
Basic algorithm: Model optimization without distillation and with standard distillation approach
Solution: Using a two-level problem for model optimization. The combination of gradients for both terms is processed by a separate model (LSTM)
Novelty: A new approach to model distillation will be proposed to significantly improve the performance of models trained in privileged information mode. It is also planned to study the dynamics of changes in hyperparameters in the optimization process.

Problem 87.2021

Title: Bayesian choice of structures of generalized linear models
Problem description: The work is devoted to testing methods for feature selection. It is assumed that the sample under study contains a significant number of multicollinear features. Multicollinearity is a strong correlation between the features selected for analysis that jointly affect the target vector, which makes it difficult to estimate regression parameters and identify the relationship between features and the target vector. There is a set of time series containing the readings of various sensors that reflect the state of the device. The readings of the sensors correlate with each other. It is necessary to choose the optimal set of features for solving the forecasting problem.
Novelty: One of the most preferred feature selection algorithms has been published. It uses structural parameters. But there is no theoretical justification. It is proposed to build a theory by describing and analyzing various functions of a priori distribution of structural parameters. In works on the search for structures of neural networks, there is also no clear theory and a list of a priori assumptions.
Data: Multivariate time series with readings from various sensors from paper 4, for starters, all samples from paper 1.

Problem 88.2021

Name: Search for the boundaries of the iris by the method of circular projections
Problem: Given a monochrome bitmap of the eye, examples. The approximate position of the center of the pupil is also known. The word "approximate" means that the calculated center of the pupil is no more than half of its true radius from the true one. It is necessary to determine the approximate positions of the circles approximating the pupil and iris. The algorithm must be very fast.
Data: About 200 thousand eye images. For each, the position of the true circles is marked - for the purpose of training and testing the method being created.
Basic algorithm: To speed up work with the image, it is proposed to aggregate data using circular projections of brightness. Circular projection is a function that depends on the radius, the value of which P(r) is equal to the integral of the directed image brightness gradient over a circle of radius r (or along an arc of a circle). Example for one arc (right quadrant) and for four arcs. Having built some circular projections, based on them, you can try to determine the position of the inner and outer borders of the iris (ring) using heuristics and / or a neural network. It is interesting to evaluate the capabilities of the neural network in this The problem.

Problem 53.2021

Title: Solution of an optimization problem combining classification and regression to estimate the binding energy of a protein and small molecules.
Problem description: The goal of the problem is to solve an optimization problem with classification and regression loss functions applied to biological data.
Data: Approximately 12,000 complexes of proteins with small molecules. For classification, for each of them there is 1 correct position in space and 18 incorrect ones generated, for regression, each complex corresponds to the value of the binding constant (proportional to energy). The main descriptors are histograms of distributions of distances between different atoms.

Base algorithm: In the classification The problem, we used an algorithm similar to linear SVM, whose relationship with the energy estimate, which is outside the scope of the classification The problem, is described in the article https://hal.inria.fr/hal-01591154/. For MSE, there is already a formulated dual The problem as a regression loss function, with the implementation of which we can start.
Solution: The first step is to solve the problem with the MSE in the loss function using a solver that is convenient for you. The main difficulty may be the large dimensionality of the data, but they are sparse. Further it will be possible to change the wording of the problem.
Novelty: Many models used to predict the interactions of proteins with ligands are "retrained" for some The problem. For example, models that are good at predicting binding energies may be poor at selecting a protein-binding molecule from a variety of non-binding ones, and models that are good at determining the correct geometry of the complex may be poor at predicting energies. In this problem, we propose to consider a new approach to combat such overfitting, since the combination of classification and regression loss functions seems to us to be a very natural regularization.

Problem 75.2021

Title: Alignment of image elements using metric models.
Problem description: Character set specified. Each symbol is represented by one file - an image. Image pixel size may vary. All images are known to belong to the same class, such as faces, letters, flowers, or cars. (A more complicated option is to one class, which we are studying and noise classes.) It is known that each image can be combined with another with the help of an equalizing transformation up to noise, or up to some average image. (This image may or may not be present in the sample). This leveling transformation is specified in the base case by a neural network, and in the proposed case - by a parametric transformation from some given class (the first is a special case of the second). The aligned image is compared with the original one using the distance function. If the distance between two images is statistically significant, it is concluded that the images belong to the same class. It is required to 1) propose an adequate model of the alignment transformation that takes into account the assumptions about the nature of the image (for example, only rotation and proportional scaling), 2) propose a distance function, 3) propose a method for finding the average image.
Data: Synthetic and real 1) pictures - faces and symbols with rotation and stretch transformation, 2) faces and cars with 3D rotation transformation with 2D projection. Synthetic images are proposed to be created manually using 1) photographs of a sheet of paper, 2) photographs of the surface of the drawing on a balloon.

Title: Detection of correlations between activity in social networks and capitalization of companies
Problem description: At present, the significant impact on stock quotes, company capitalization and the success or failure of an IPO depends on social factors such as public opinion expressed on social media. A recent notable example is the change in GameStore quotes caused by the surge in activity on Reddit. Our The problem at the first stage is to identify quotes between the shares of companies in different segments and activity in social networks. That is, it is necessary to identify correlations between significant changes in the company's capitalization and previous bursts (positive or negative) of its discussion in social networks. That is, it is necessary to find the minimum of the loss function when restoring the dependence in various classes of models (parametrics, neural networks, etc.). This The problem is part of a large project to analyze the analysis of markets and the impact of social factors on risks (within a team of 5-7 professors), which will lead to a series of publications sufficient to defend a dissertation.
Data: The problem has a significant engineering context, the data is downloads from quotes on the Moscow Exchange, as well as NYT and reddit data (crawling and parsing is done by standard tools). The student working on this The problem must have strong engineering skills and a desire to engage in both the practice of machine learning and the engineering parts of The problem.

Problem 88b.2021

Name: Finding a Pupil in an Eye Image Using the Luminance Projection Method
Problem: Given a monochrome bitmap of the eye, examples. It is necessary to determine the approximate coordinates of the center of the pupil. The word "approximate" means that the calculated pupil center must lie inside a circle centered at the pupil's true center and half the true radius. The algorithm must be very fast.
Data: About 200 thousand eye images. For each, the position of the true circle is marked - for the purpose of training and testing the method being created.

Basic algorithm: To speed up work with the image, it is proposed to aggregate data using brightness projections. Image brightness is a function of two discrete arguments. Its projection on the horizontal axis is equal to. Similarly, projections are constructed on axes with an inclination. Having built several projections (two, four), based on them, you can try to determine the position of the pupil (compact dark area) using heuristics and / or a neural network. It is interesting to evaluate the capabilities of the neural network in this The problem.

Problem 88c.2021

Name: Searching for a century in an image as a parabolic contour using the projection method.
Problem: Given a monochrome bitmap of the eye, examples. It is necessary to find the contour of the upper eyelid as a parabola, that is, to determine the parameters.
Data: About 200 thousand eye images. For some (about 2500), a human expert marked the position of a parabola that approximates the eyelid.
Basic algorithm: The first step is pre-processing the image with a vertical gradient filter with further binarization, below is a typical result. There are various options for the next step. For example, if the coordinates of the pupil are known, you can set the region of interest (from above) and in it, using the selected points, construct a parabola by approximation using the least squares method. An example result is given below. More subtle methods are possible, such as finding a parabola using the Hough transform (see Wikipedia). Another way is to use projective methods (Radon transform). The main idea: after specifying the coefficient , apply a coordinate transformation to the image, as a result of which all parabolas of the form formula turn into lines of the form , then, given the coefficient , apply the coordinate transformation where , after which the oblique lines of the formula form become horizontal, which are easy to determine, for example, by horizontal projection (by summing the values in the rows of the matrix of the resulting image. If the coefficients are guessed correctly, the perabola representing the eyelid will give a clear maximum in the projection. By going through the formula (having a physical meaning), you can find those that give the maximum projection value, and consider that the desired parabola - eyelid.

Problem 62.2021

Title: Construction of a method for dynamic alignment of multidimensional time series, resistant to local signal fluctuations.
Problem description: In the process of working with multidimensional time series, the situation of the close proximity of sensors corresponding to different measurement channels is common. As a result, small signal shifts in space can lead to signal peak fixation by neighboring sensors, which leads to significant differences in measurements in terms of L2 distance.
Thus, small signal shifts lead to significant fluctuations in the readings of the sensors. The problem of constructing a distance function between points of time series that is resistant to noise generated by small spatial signal shifts is considered. It is necessary to consider the problem in the approximation of the presence of a map of the location of the sensors.
Data:
1. Monkey brain activity measurements
2. Artificially created data (several options must be proposed, for example signal movement in space clockwise and counterclockwise)
References:
Base algorithm: L2 distance between a pair of measurements.
Solution: Use the DTW distance function between two multidimensional time series. Two time axes are aligned, while inside the DTW functional, the distance between the i-th and j-th measurements is chosen such that it is resistant to local “shifts” of the signal. It is required to offer such functionality. The basic solution is L2, the improved solution is DTW between the i-th and j-th dimensions (dtw inside dtw).
You can suggest some modification, for example, the distance between the hidden layers of the autoencoder for points i and j.
Novelty: A method for aligning multidimensional time series is proposed that takes into account small signal fluctuations in space.

Problem 63.2021

Title: Hierarchical alignment of time sequences.
Problem description: The problem of alignment of sequences of difficult events is considered. An example is the complex behavior of a person: when considering data from IMU sensors, one can put forward a hypothesis: there is an initial signal, there are aggregates of “elementary actions” and there are aggregates of “actions” of a person. Each of the indicated levels of abstraction can be distinguished and operated on exactly by it.
In order to accurately recognize the sequence of actions, it is possible to use metric methods (for example, DTW, as a method that is resistant to time shifts). For a more accurate quality of timeline alignment, it is possible to carry out alignment at different levels of abstraction.
It is proposed to explore such a hierarchical approach to sequence alignment, based on the possibility of applying alignment algorithms to objects of different structures, having a distance function on them.
References:
Base algorithm: classic DTW.
Solution: It is proposed to perform the transition from one level of abstraction to another by using convolutional and recurrent neural networks. Then the object at the lower level of abstraction is the original signal. At the second level - a signal from the hidden layer of the model (built on the objects of the lower level), the dimension of which is much less, and the upper layer - a signal from the hidden layer of the model (built on the objects of the middle level).
In this case, DTW is calculated separately between the lower , between the middle and between the upper levels, but the formation of objects for calculating the distance is carried out taking into account the alignment path between the objects of the previous level.
This method is considered as a way to increase the interpretability of the alignment procedure and the accuracy of the action classification in connection with the transition to higher-level patterns. In addition, a significant increase in speed is expected.
Novelty: The idea of aligning time sequences simultaneously at several levels of abstraction is proposed. The method should significantly improve the interpretability of alignment algorithms and increase their speed.

Title: Predicting the quality of protein models using spherical convolutions on 3D graphs.
Problem: The purpose of this work is to create and study a new convolution operation on three-dimensional graphs in the framework of solving the problem of assessing the quality of three-dimensional protein models (The problem regression on graph nodes).
Data: Models generated by CASP competitors are used (http://predictioncenter.org).

3. [18] Geometric deep learning: going beyond euclidean data.
Base algorithm: As a basic algorithm, we will use a neural network based on the graph convolution method, which is generally described in [19].
Solution: The presence of a peptide chain in proteins makes it possible to uniquely introduce local coordinate systems for all graph nodes, which makes it possible to create and apply spherical filters regardless of the graph topology.
Novelty: In the general case, graphs are irregular structures, and in many graph learning The problems, the sample objects do not have a single topology. Therefore, the existing operations of convolutions on graphs are greatly simplified or do not generalize to different topologies. In this paper, we propose to consider a new method for constructing a convolution operation on three-dimensional graphs, for which it is possible to uniquely choose local coordinate systems associated with each node.

Problem 44+. 2021

Title: Early prediction of sufficient sample size for a generalized linear model.
Deiscription: The problem of experiment planning is investigated. The problem of estimating a sufficient sample size according to the data is solved. The sample is assumed to be simple. It is described by an adequate model. Otherwise, the sample is generated by a fixed probabilistic model from a known class of models. The sample size is considered sufficient if the model is restored with sufficient confidence. It is required, knowing the model, to estimate a sufficient sample size at the early stages of data collection.
Goal: On a small simple iid sample, predict the error on a replenished large one. The predictive model is smooth monotonic in two derivatives. The choice of model is a complete enumeration or genetics. The model depends on the reduced (explore) covariance matrix of the GLM parameters.
Data: For the computational experiment, it is proposed to use classical samples from the UCI repository. Link to selections https://github.com/ttgadaev/SampleSizeEstimation/tree/master/datasets
References:

Bishop, C. 2006. Pattern Recognition and Machine Learning. Berlin: Springer. 758 p.

Basic algorithm: We will say that the sample size is sufficient if the log-likelihood has a small variance on a sample of size m calculated using the bootstrap.

We are trying to approximate the dependence of the average value of log-likelihood and its variance on the sample size.

Solution: The methods described in the review are asymptotic or require a deliberately large sample size. The new method should be to predict volume in the early stages of experiment design, i.e. when data is scarce.

Basic algorithm: Unsupervised Machine Translation Using Monolingual Corpora Only.
Solution: As a translation model, it is proposed to consider a combination of two auto-encoders, each of which is responsible for presenting sentences in one of the languages. The models are optimized in such a way that the latent spaces of autoencoders for different languages match.

Problem 8.2021

Title: Generation of features using locally approximating models (Classification of human activities according to measurements of fitness bracelets).
Problem: It is required to check the feasibility of the hypothesis about the simplicity of sampling for the generated features. Features are the optimal parameters of approximating models. Moreover, the entire sample is not simple and requires a mixture of models to approximate it. Explore the information content of the generated features - the parameters of the approximating models trained on the segments of the original time series. According to the measurements of the accelerometer and gyroscope, it is required to determine the type of activity of the worker. It is assumed that the time series of measurements contain elementary movements that form clusters in the space of time series descriptions. The characteristic duration of the movement is seconds. Time series are labeled with activity type labels: work, leisure. The typical duration of activity is minutes. It is required to restore the type of activity according to the description of the time series and cluster.

Each local model approximates a connected region in feature space. It is assumed that the set of local models cover the entire space of objects. A convex combination of local models is considered as an aggregating function. As the coefficients of the convex combination, we consider a function depending on the object --- the gate function.
Required: To construct an algorithm for optimizing the parameters of local models and parameters of the gate function. It is required to propose a metric in the space of objects, a metric in the space of models.

Title: Search for the boundaries of the iris by the method of circular projections
Problem: Given a monochrome bitmap of the eye, see examples (https://cloud.mail.ru/public/2DBu/5c6F6e3LC). The approximate position of the center of the pupil is also known. The word "approximate" means that the calculated center of the pupil is no more than half of its true radius from the true one. It is necessary to determine the approximate positions of the circles approximating the pupil and iris. The algorithm must be very fast.
Data: About 200 thousand eye images. For each, the position of the true circle is marked - for the purpose of training and testing the method being created.
Base algorithm: To speed up work with the image, it is proposed to aggregate data using circular projections of brightness. Circular projection is a function that depends on the radius, the value of which P(r) is equal to the integral of the directed image brightness gradient over a circle of radius r (or along an arc of a circle). Example for one arc (right quadrant) and for four arcs. Having built some circular projections, based on them, you can try to determine the position of the inner and outer borders of the iris (ring) using heuristics and / or a neural network. It is interesting to evaluate the capabilities of the neural network in this The problem.

Title: Construction of local and universal interpretable scoring models
Problem: Build a simple and interpretable scoring system as a superposition of local models, taking into account the requirements for the system to retain knowledge about key customers and features (in other words, take into account new economic phenomena). The model must be a superposition, and each element must be controlled by its own quality criterion. Introduce a schedule for optimizing the structure and parameters of the model: the system must work in a single optimization chain. Propose an algorithm for selecting features and objects.
Data:

Data from OTP Bank. The sample contains records of 15,223 clients classified into two classes: 1 - there was a response (1812 clients), 0 - there was no response (13411 clients). Feature descriptions of clients consist of 50 features, which include, in particular, age, gender, social status in relation to work, social status in relation to pension, number of children, number of dependents, education, marital status, branch of work. The data are available at the following addresses: www.machinelearning.ru/wiki/images/2/26/Contest_MMRO15_OTP.rar (sample A), www.machinelearning.ru/wiki/images/5/52/Contest_MMRO15_OTP_(validation).rar (sample B).

Solution: It is proposed to build a scoring system containing such a preprocessing block as a block for generating metric features. It is proposed to investigate the influence of the non-equivalence of objects on the selection of features for the model, to investigate the joint selection of features and objects when building a model. It is required to implement a schedule for optimizing the model structure using an algorithm based on the analysis of covariance matrices of model hyperparameters. The schedule includes a phased replenishment of the set of features and objects. The feature sample size will be determined by controlling the error variance. The main criterion for the quality of the system: ROC AUC (Gini).
Novelty:

The model structure optimization schedule must satisfy the requirement to rebuild the model at any time without losing its characteristics.
Accounting for the unequal value of objects in the selection of features

Title: Variational optimization of deep learning models with model complexity control
Problem: The problem of optimizing a deep learning model with a predetermined model complexity is considered. It is required to propose a model optimization method that allows generating new models with a given complexity and low computational costs.
Data:MNIST, CIFAR

3. [3] network factories https://papers.nips.cc/paper/6304-convolutional-neural-fabrics.pdf
Base algorithm: Random search
Solution: The proposed method is to represent a deep learning model as a hypernet (a network that generates the parameters of another network) using a Bayesian approach. Probabilistic assumptions about the parameters of deep learning models are introduced, and a variational lower estimate of the Bayesian validity of the model is maximized. The variation estimate is considered as a conditional value depending on the external parameter of complexity.
Novelty: The proposed method allows generating models in one-shot mode (practically without retraining) with the required model complexity, which significantly reduces the cost of optimization and retraining.

Title: Theoretical validity of the application of metric classification methods using dynamic alignment (DTW) to spatiotemporal objects.
Problem description: It is necessary to study the existing theoretical justifications for applying dynamic alignment methods to various objects, and explore the use of such methods for space-time series.
When proving the applicability of alignment methods, it is proved that the function generated by the dynamic alignment algorithm is the core. Which, in turn, justifies the use of metric classification methods.
References:
Solution: For different formulations of the DTW method (when the internal function of the distance between time series samples is different) - find and collect evidence that the function is the kernel in one place.
For a basic set of datasets with time series (on which the accuracy of distance functions is checked ) check the fulfillment of the conditions from the Mercer theorem (positive definiteness of the matrix). Do this for various modifications of the DTW distance function. (Sakoe-Chiba band, Itakura band, weighted DTW.)

Title: Deep learning for RNA secondary structure prediction
Problem: RNA secondary structure is an important feature which defines RNA functional properties. Its importance can be illustrated by the fact, that it is evolutionary preserved and some types of functional RNAs always * have the same secondary structure, for example all tRNAs fold into cloverleaf. As secondary structure often defines functions, knowing RNAs secondary structure may help investigate functions of novel RNA molecules. RNA folding is not as easy as DNA folding, because RNA is single stranded molecule which forms complicated base-pairing interactions, while DNA mostly exists as fully base paired double helices. Current methods of RNA structure prediction rely on experimentally evaluated thermodynamic rules, but with thermodynamics alone only 80% of structures can be accurately predicted. We propose an AI-driven method for predicting RNA secondary structure inspired by neural machine translation model.
Data: RNA sequences in form of strings of characters

Title: Dynamic alignment of multidimensional time series.
Problem description: A characteristic multidimensional time series is the trajectory of a point in 3-dimensional space. The two trajectories need to be optimally aligned with each other. For this, the distance DTW between two time series is used. In the classical representation, DTW is built between one-dimensional time series. It is necessary to introduce various modifications of the algorithm for working with high-dimensional time series: trajectories, corticograms.

Title: Deep Learning for reliable detection of tandem repeats in 3D protein structures more in PDF
Problem: Deep learning algorithms pushed computer vision to a level of accuracy comparable or higher than a human vision. Similarly, we believe that it is possible to recognize the symmetry of a 3D object with a very high reliability, when the object is represented as a density map. The optimization problem includes i) multiclass classification of 3D data. The output is the order of symmetry. The number of classes is ~10-20 ii) multioutput regression of 3D data. The output is the symmetry axis (a 3-vector). The input data are typically 24x24x24 meshes. The total amount of these meshes is of order a million. Biological motivation : Symmetry is an important feature of protein tertiary and quaternary structures that has been associated with protein folding, function, evolution, and stability. Its emergence and ensuing prevalence has been attributed to gene duplications, fusion events, and subsequent evolutionary drift in sequence. Methods to detect these symmetries exist, either based on the structure or the sequence of the proteins, however, we believe that they can be vastly improved.
Data: Synthetic data are obtained by ‘symmetrizing’ folds from top8000 library (http://kinemage.biochem.duke.edu/databases/top8000.php).
References: Our previous 3D CNN: [27] Invariance of CNNs (and references therein): 01630265/document, [28]
Basic algorithm: A prototype has already been created using the Tensorflow framework [4], which is capable of detecting the order of cyclic structures with about 93% accuracy. The main goal of this internship is to optimize the topology of the current neural network prototype and make it rotational and translational invariant with respect to input data. [4] [29]
Solution: The network architecture needs to be modified according to the invariance properties (most importantly, rotational invariance). Please see the links below [30], [31] The code is written using the Tensorflow library, and the current model is trained on a single GPU (Nvidia Quadro 4000)of a desktop machine.
Novelty: Applications of convolutional networks to 3D data are still very challenging due to large amount of data and specific requirements to the network architecture. More specifically, the models need to be rotationally and transnationally invariant, which makes classical 2D augmentation tricks loosely applicable here. Thus, new models need to be developed for 3D data.

Title: Automatic setting of ARTM parameters for a wide class of The problems.
Problem description: The bigARTM open library allows you to build topical models using a wide class of possible regularizers. However, this flexibility makes The problem of setting the coefficients very difficult. This tuning can be greatly simplified by using the relative regularization coefficients mechanism and automatic selection of N-grams. We need to test the hypothesis that there is a universal set of relative regularization coefficients that gives "reasonably good" results on a wide class of problems. Several datasets are given with some external quality criterion (for example, classification of documents into categories or ranking). We find the best parameters for a particular dataset, giving the "locally the best model". We find the bigARTM initialization algorithm that produces thematic models with quality comparable to the "locally best model" on its dataset. Comparability criterion in quality: on this dataset, the quality of the "universal model" is no more than 5% worse than that of the "locally best model".

Title: Forecasting intentions. Building an optimal signal decoding model for modeling a brain-computer interface.
Problem: The Brain Computer Interface (BCI) allows you to help people with disabilities regain their mobility. According to the available description of the device signal, it is necessary to simulate the behavior of the subject.
Data: Data sets of ECoG/EEG brain signals.
References:

Basic algorithm: It is proposed to compare with the partial least squares algorithm.
Solution: In this work, it is proposed to build a single system that solves the problem of signal decoding. As stages of building such a system, it is proposed to solve the problems of data preprocessing, feature space extraction, dimensionality reduction and selection of a model of optimal complexity. It is proposed to use the tensor version of PLS with feature selection.
Novelty: In the formulation of the problem, the complex nature of the signal is taken into account: a continuous trajectory of movement, the presence of discrete structural variables (fingers or joint movement), the presence of continuous variables (position of a finger or limb).

Title: Optimal Approximation of Non-linear Power Flow Problem
Problem: Our goal is to approximate the solution of non-linear non-convex optimal power flow problem by solving a sequence of convex optimization problems (aka trust region approach). On this way we propose to compare various approaches for an approximate solution of this problem with adaptive approximation of the power flow non-linearities with a sequence of quadratic and/or piece-wise linear functions
Data: Matpower module from MATLAB contains all necessary test cases. Start considering IEEE 57 bus case.

Title: Investigation of reference objects in the problem of metric classification of time series.
Problem description: The DTW function is the distance between two time series that can be non-linearly warped relative to each other. It looks for the best alignment between two objects, so it can be used in a metric object classification problem. One of the methods for solving the problem of metric classification is measuring distances to reference objects and using the vector of these distances as an indicative description of the object. The DBA method is an algorithm for constructing centroids (reference objects) for time series based on the DTW distance. When plotting the distance between the time series and the centroid, different pairs of values (eg peak values) are more specific to one of the classes, and the impact of such coincidences on the distance value should be higher.

It is necessary to explore various ways of constructing reference objects, as well as determining their optimal number. The criterion is the quality of the metric classifier in The problem. In the DBA method, for each centroid, it is proposed to create a weight vector that demonstrates the "significance" of the measurements of the centroid, and use it in the modified weighted-DTW distance function.

Data: The data describes 6 classes of time series from the mobile phone's accelerometer. https://sourceforge.net/p/mlalgorithms/code/HEAD/tree/Group274/Goncharov2015MetricClassification/data/
References:
Base algorithm: Implement basic methods:
1. Selection of a subset of training sample objects as reference
2. Pre-processing of anomalous objects
3. Clustering training sample objects to build centroids within the cluster
4. Using the DBA method to build reference objects
5. Using numerical optimization methods to find the optimal vector of weights with given constraints
Solution: Extension of constraint types to weight vector type: binary vector, same vector for all centroids, binary same vector for all centroids. Such a solution will save energy costs during the operation of sensors of a mobile device.

Literature research and a combination of up-to-date methods.

Novelty: There has not been a comprehensive study of various methods of constructing centroids and reference elements along with the choice of their optimal number.

Name: Early prediction of sufficient sample size for a generalized linear model.
Problem: The problem of designing an experiment is being investigated. The problem of estimating a sufficient sample size according to the data is solved. The sample is assumed to be simple. It is described by an adequate model. Otherwise, the sample is generated by a fixed probabilistic model from a known class of models. The sample size is considered sufficient if the model is restored with sufficient confidence. It is required, knowing the model, to estimate a sufficient sample size at the early stages of data collection.
Data: For the computational experiment, it is proposed to use classical samples from the UCI repository. Link to samples https://github.com/ttgadaev/SampleSize/tree/master/datasets

Basic algorithm: We will say that the sample size is sufficient if the log-likelihood has a small variance, on a sample of size m calculated using bootstrap.

We are trying to approximate the dependence of the average value of log-likelihood and its variance on the sample size.

Solution: The methods described in the review are asymptotic or require a deliberately large sample size. The new method should be to predict volume in the early stages of experiment design, i.e. when data is scarce.

Title: Formulation and solution of an optimization problem combining classification and regression to estimate the binding energy of a protein and small molecules. The problem description [35]
Problem: From a bioinformatics point of view, The problem is to estimate the free energy of protein binding to a small molecule (ligand): the best ligand in its best position has the lowest free energy of interaction with the protein. (Following a large text, see the file at the link above.)
Data:
1. Data for binary classification. Approximately 12,000 protein-ligand complexes: for each of them there is 1 native position and 18 non-native ones. The main descriptors are histograms of distributions of distances between different atoms of the protein and ligand, the dimension of the vector of descriptors is ~ 20,000. In the case of continued research and publication in a specialized journal, the set of descriptors can be expanded. The data will be provided as binary files with a python script to read.
2. Data for regression. For each of the presented complexes, the value of the quantity is known, which can be interpreted as the binding energy.
References:
1. SVM [36]
2. Ridge Regression [37]
3. [38] (section 1)
Basic algorithm: [39] In the classification problem, we used an algorithm similar to linear SVM, whose relationship with the energy estimate is beyond the scope of the classification problem, described in the above article. Various loss functions can be used in a regression problem.
Solution: It is necessary to connect the previously used optimization problem with the regression problem and solve it using standard methods. Cross-validation will be used to check the operation of the algorithm. There is a separate test set consisting of (1) 195 complexes of proteins and ligands, for which it is necessary to find the best ligand pose (the algorithm for obtaining ligand positions differs from that used in training), (2) complexes of proteins and ligands, for which native poses it is necessary to predict the energy binding, and (3) 65 proteins for which the most strongly binding ligand is to be found.
Novelty: First of all, the interest is combining classification and regression problems. The correct assessment of the quality of protein and ligand binding is used in drug development to search for molecules that interact most strongly with the protein under study. Using the classification problem described above to predict the binding energy results in an insufficiently high correlation of predictions with experimental values, while using the regression problem alone leads to overfitting.

Title: Creation of ranking models for information retrieval systems. Algorithm for Predicting the Structure of Locally Optimal Models
Problem: It is required to predict a time series using some parametric superposition of algebraic functions. It is proposed not to cost the prognostic model, but to predict it, that is, to predict the structure of the approximating superposition. A class of considered superpositions is introduced, and on the set of such structural descriptions, a search is made for a locally optimal model for the problem under consideration. The problem consists in 1) searching for a suitable structural description of the model 2) describing the search algorithm for the structure that will correspond to the optimal model 3) describing the algorithm for inverse construction of the model according to its structural description. For an already existing example of the answer to questions 1-3, see the works of A. A. Varfolomeeva.
Data:
1. Collection of text documents TREC (!)
2. A set of time series, which implies the restoration of functional dependencies. It is proposed to first use synthetic data or immediately apply the algorithm to forecasting time series 1) electricity consumption 2) physical activity with subsequent analysis of the resulting structures.

Base algorithm: Described in [1]. Developed in the work of the 974 group team. It is proposed to use their code and experiment.
Solution: It is proposed to try to repeat the experiment of A. A. Varfolomeeva for a different structural description in order to understand what is happening. The superposition of algebraic functions defines an ortree, on the vertices of which the labels of the corresponding algebraic functions or variables are given. Therefore, the structural description of such a superposition can be its DFS-code. This is a string consisting of vertex labels, written in the order in which the tree is traversed by depth-first search. Knowing the arities of the corresponding algebraic functions, we can restore any such DFS-code in O(n) and get back the superposition of functions. On the set of similar string descriptions, it is proposed to search for the string description that will correspond to the optimal model.

Name: The problem of searching characters in images
Problem description: This The problem in one of the formulation options can be reduced to two sequential operations: 1) searching for objects in the image and determining their class 2) searching the database for information about the symbolic meaning of the found objects. The main difficulty in solving the problem lies in the search for objects in the image. However, the following classification may also be difficult due to the fact that the image of the object may be incomplete, unusually stylized, and the like.

Title: Automatic construction of a neural network of optimal complexity
Problem: The problem of finding a stable (and not redundant in terms of parameters) neural network structure is considered. The neural network is considered as a computational graph, the edges of which are primitive functions, and the vertices are intermediate representations of the sample obtained under the action of these functions. It is required to choose a subgraph of the model, in which the final neural network will give an acceptable classification quality with a small number of parameters.

Title: Finding paraphrases.
Problem description: Paraphrases are different variations of the same and the same text, identical in meaning, but differing lexically and grammatically, for example: "Where did the car go" and "Which direction did the car go". The problem of detecting paraphrases is to select clusters in a set of texts, such that each cluster contains only paraphrases of the same and the same sentence. The easiest way to extract paraphrases is to cluster texts, where each text is represented by a "bag of words".
Data: There are open datasets of questions for testing and training on kaggle.com, there are open datasets for testing from semeval conferences.
Base algorithm: Use one of the document clustering algorithms to extract paraphrases, where each document is represented by a bag of words or tf-idf.
Solution: Use neural network architectures to search for paraphrases, use phrases extracted with parsers as features, use multilevel clustering.
Novelty: Lack of implementations for the Russian language that will use parsers for a similar The problem, all current solutions are quite "simple".

Title: On conformational changes of proteins using collective motions in torsion angle space and L1 regularization.
Problem description: Torsion angles are the most natural degrees of freedom for describing motions of polymers, such as proteins. This is because bond lengths and bond angles are heavily constrained by covalent forces. Thus, multiple attempts have been done to describe protein dynamics in the torsion angle space. For example, one of us has developed an elastic network model (ENM) [1] in torsion angle space called Torsional Network Model (TNM) [2]. Functional conformational changes in proteins can be described in the Cartesian space using just a subset of collective coordinates [3], or even a sparse representation of these [4]. The latter requires a solution of a LASSO optimization problem [5]. The goal of the current project is to study if a sparse subset of collective coordinates in the torsion subspace can describe functional conformational changes in proteins. This will require a solution of a ridge regression problem with a L1 regularization constraint. The starting point will be the LASSO formulation.
Data: Experimental conformations will be extracted from the Protein Docking Benchmark v5 (https://zlab.umassmed.edu/benchmark/) and a few others. The TNM model can be downloaded from https://ub.cbm.uam.es/tnm/tnm_soft_main.php

Base algorithm: The starting point will be a combination of methods from references 2 and 4. It has to be a LASSO formulation with the direction vectors reconstructed from the internal coordinates. The quality will be computed based on the RMSD measure between the prediction and the solution on several benchmarks. Results will be presented with statistical plots (see examples in references 3-4.
Novelty: This is an important and open question in computational structural bioinformatics - how to efficiently represent transitions between protein structures. Not much has been done in the torsional angle subspace (internal coordinates)[6] and nearly nothing has been done using L1 regularization [4].

Name: Study of the dependence of the quality of recognition of ontological objects on the depth of hyponymy.
Problem description: It is necessary to investigate the dependence of the quality of recognition of ontological objects at different levels of concept hyponymy. The classic formulation of the problem of named entity recognition: https://en.wikipedia.org/wiki/Named-entity_recognition
Data: Hyponyms from https://wordnet.princeton.edu/ , texts from different domains presumably from WebOfScience.
References: Relevant articles for classical staging http://arxiv-sanity.com/search?q=named+entity+recognition
Basic algorithm: https://arxiv.org/pdf/1709.09686.pdf or its simplified version can be used as an algorithm, studies are performed using the DeepPavlov library.
Solution: It is necessary to collect a dataset of hyponymy (nesting of concepts) of objects using WordNet, to automatically mark up ontological objects of texts of various domains for several levels of generalization of concepts, to conduct a series of experiments to determine the quality of recognition of ontological objects for different levels of nesting.

Title: High order convex optimization methods
Problem description: High-order methods are effectively (up to n ~ 10^3 sometimes even up to n ~ 10^4) used for convex problems of not very large dimensions. Until recently, it was generally accepted that these are second-order methods (using the second derivatives of the function being optimized). However, at the beginning of 2018 Yu.E. Nesterov [1] proposed an efficient third-order method in the theory, which works according to almost optimal estimates. In the manual [3] in exercise 1.3, an example of a "bad" convex function proposed by Yu.E. Nesterov, on which I would like to compare the Nesterov method of the second and third order [1], the method from [2] of the second and third order and the usual fast gradient methods (of the first order). It is worth comparing both by the number of iterations and by the total running time.

Title: Cutting plane methods for copositive optimization
Problem: Conic program over the copositive cone (copositive program) min <C,X> : <A_i,X> = b_i, X \in \Pi_i C^k_i, k_i <= 5 A linear function is minimized over the intersection of an affine subspace with a product of copositive cones of orders k_i <= 5.
Data: The algorithm will be tested on randomly generated instances

Solution: The copositive program will be solved by a cutting plane algorithm. The cutting plane (in the case of an infeasible iterate) will be constructed from the semidefinite representation of the diagonal 1 section of the cone proposed in [1]. The algorithm will be compared to a simplicial division method proposed in [2], [4]. General information about copositive programs and their applications in optimization can be found in [3] .
Novelty: The proposed algorithm for optimization over copositive cones up to order 5 uses an exact semi-definite representation. In contrast to all other algorithms existing today the generation of cutting planes is non-iterative.

Title: Fractal analysis and synthesis of optical images of sea waves
Problem description: A variety of physical processes and phenomena are studied with the help of images obtained remotely. An important The problem is to obtain adequate information about the processes and phenomena of interest by measuring certain image characteristics. Lines of equal brightness (isolines) on the images of many natural objects are fractal, that is, they are sets of points that cannot be represented by lines of finite length and occupy an intermediate position between lines and two-dimensional flat figures. Such sets are characterized by the fractal dimension D, which generalizes the classical concept of the dimension of a set and can take fractional values. For a solitary point on the image D=0, for a smooth curve D=1, for a flat figure D=2. The fractal isoline has the dimension 1<D<2. The algorithm for calculating D is given, for example, in [1]. The fractal dimension of the sea surface isolines can serve to estimate the spatial spectra of sea waves according to remote sensing data [1]. The problem is as follows. It is necessary to conduct a numerical study of the relationship between the characteristics of the spatial spectra of sea waves and the fractal dimension of satellite images of the Earth in the solar glare region. For the study, the method of numerical synthesis of optical images of sea waves, described in [2], should be used. Numerical modeling should be done with different characteristics of sea waves, as well as with different positions of the Sun and spatial resolution of images.

Name Entropy maximization for various types of image transformations
Problem description: Pansharpening is an algorithm for upscaling multispectral images using a reference image. The problem of pansharpening is formulated as follows: having a panchromatic image of the required resolution and a multispectral image of reduced resolution, it is required to restore the multispectral image in the spatial resolution of the panchromatic one. From empirical observations based on a large number of high-resolution images, it is known that the spatial variability of the reflected radiation intensity for objects of the same nature is much greater than the variability of their spectrum. In other words, one can observe that the spectrum of reflected radiation is homogeneous within the boundaries of one object, while even within one object the intensity of reflected radiation varies. In practice, good results can be achieved using a simplified approach, in which it is assumed that if the intensity of neighboring regions differ significantly, then these regions probably belong to different objects with different reflected spectra. This is the basis for the developed probabilistic algorithm for increasing the resolution of multispectral images using a reference image [1]
It is necessary to conduct a study on maximizing the entropy for various types of transformations on the image. Show that entropy can serve as an indicator of the loss of information contained in the image during transformations over it. Formulation of the inverse problem for image restoration: Condition 1: Correspondence of the intensity (at each point) of the restored image with the intensity of the panchromatic image. Condition 2: Correspondence of the low-frequency component of the reconstructed image with the original multispectral image. Condition 3: Homogeneity (similarity) of the spectrum within one object and the assumption of an abrupt change in the spectrum at the border of two homogeneous regions. Condition 4: Under the first three conditions, the local entropy of the reconstructed image must be maximized.

Title: Automatic detection and recognition of objects in images
Problem description: Automatic detection and recognition of objects in images and videos is one of the main The problems of computer vision. As a rule, these The problems are divided into several subThe problems: preprocessing, extraction of the characteristic properties of the object image and classification. The pre-processing stage usually includes some operations on the image such as filtering, brightness equalization, geometric corrective transformations to facilitate robust feature extraction.

The characteristic properties of an image of an object are understood as a set of features that approximately describe the object of interest. Features can be divided into two classes: local and integral. The advantage of local features is their versatility, invariance with respect to uneven changes in brightness and illumination, but they are not unique. Integral features that characterize the image of the object as a whole are not resistant to changes in the structure of the object and difficult lighting conditions. There is a combined approach - the use of local features as elements of an integral description, when the desired object is modeled by a set of areas, each of which is characterized by its own set of features - a local texture descriptor. The totality of such descriptors characterizes the object as a whole. Classification is understood as determining whether an object belongs to a particular class by analyzing the feature vector obtained at the previous stage, dividing the feature space into subdomains indicating the corresponding class. There are many approaches to classification: neural network, statistical (Bayesian, regression, Fisher, etc.), decision trees and forests, metric (nearest K-neighbors, Parzen windows, etc.) and nuclear (SVM, RBF, method of potential functions), compositional (AdaBoost). For The problem of detecting an object in an image, membership in two classes is evaluated - the class of images containing the object, and the class of images that do not contain the object (background images).

Solution: One of the options for generalizing LBP can be to use instead of histograms of distribution of points by LBP code, histograms of distribution of modules of point gradients in a block by LBP code (HG-LBP). It is proposed to use the OpenCV library for the basis of experiments, in which the HOG and LBP algorithms are implemented. It is necessary to modify the source code of the LBP implementation and insert the calculation of the modules of the gradient and the accumulation of the corresponding histogram over the LBP. It is necessary to write a program for reading the INRIA base, learning the linear SVM method on the original and modified descriptors, collecting detection statistics and plotting FAR/FRR DET plots.
Novelty: The development of computationally simple methods for extracting the most informative features in recognition The problems is relevant in the field of creating embedded systems with low computing resources. Replacing the composition of descriptors with one that is more informative than each individually can simplify the solution of the problem. The use of gradient values in LPB descriptor histograms is new.

Solution: One of the options for generalizing the HOG algorithm can be to use another classifier instead of the linear SVM algorithm, for example, some kind of neural network. It is proposed to use the OpenCV library for the basis of experiments, which implements the HOG algorithm and the SVM classifier. It is necessary to analyze the source code of the HOG implementation, formalize the internal structure of the descriptor HOG vector in the form of a three-dimensional tensor — two spatial and one spectral dimensions. It is necessary to write a program for reading the INRIA base, learning the linear SVM method on HOG descriptors from it, collecting detection statistics and plotting FAR/FRR DET plots. Based on some neural network training system (for example, mxnet), it is necessary to assemble a shallow (no more than 2-3 convolutional layers) convolutional neural network of known architecture, train it on the basis of INRIA and on HOG tensor descriptors, build the corresponding FAR / FRR graphs.
Novelty: The development of computationally simple methods for extracting the most informative features in recognition The problems is relevant in the field of creating embedded systems with low computing resources. Using a small number of the most informative descriptors can reduce computational complexity compared to using a large composition of simple features, such as in a deep convolutional neural network. Typically, classifiers use the HOG descriptor as a vector as a whole, however, information about the local spatial structure and feature spectrum is lost. The novelty lies in the use of the block locality property in the HOG descriptor and the representation of the HOG as a 3D tensor. The use of this information makes it possible to achieve detection resistance to pedestrian overlap.

Title: Automatic determination of the relevance of neural network parameters.
Problem: The problem of finding a stable (and not redundant in terms of parameters) neural network structure is considered. To cut off redundant parameters, it is proposed to introduce a priori probabilistic assumptions about the distribution of parameters and remove non-informative parameters from the neural network using the Belsley method. To adjust the prior distribution, it is proposed to use gradient methods.
Data: A selection of handwritten MNIST digits
Basic algorithm: Optimal Brain Damage, decimation based on variance inference. The structure of the final model is proposed to be compared with the model obtained by the AdaNet algorithm.

Title: Deep Learning for reliable detection of tandem repeats in 3D protein structures more in PDF
Problem: Deep learning algorithms pushed computer vision to a level of accuracy comparable or higher than a human vision. Similarly, we believe that it is possible to recognize the symmetry of a 3D object with a very high reliability, when the object is represented as a density map. The optimization problem includes i) multiclass classification of 3D data. The output is the order of symmetry. The number of classes is ~10-20 ii) multioutput regression of 3D data. The output is the symmetry axis (a 3-vector). The input data are typically 24x24x24 meshes. The total amount of these meshes is of order a million. Biological motivation : Symmetry is an important feature of protein tertiary and quaternary structures that has been associated with protein folding, function, evolution, and stability. Its emergence and ensuing prevalence has been attributed to gene duplications, fusion events, and subsequent evolutionary drift in sequence. Methods to detect these symmetries exist, either based on the structure or the sequence of the proteins, however, we believe that they can be vastly improved.
Data: Synthetic data are obtained by ‘symmetrizing’ folds from top8000 library (http://kinemage.biochem.duke.edu/databases/top8000.php).
References: Our previous 3D CNN: [63] Invariance of CNNs (and references therein): 01630265/document, [64]
Base algorithm: A prototype has already been created using the Tensorflow framework [4], which is capable of detecting the order of cyclic structures with about 93% accuracy. The main goal of this internship is to optimize the topology of the current neural network prototype and make it rotational and translational invariant with respect to input data. [4] [65]
Solution: The network architecture needs to be modified according to the invariance properties (most importantly, rotational invariance). Please see the links below [66],

[67] The code is written using the Tensorflow library, and the current model is trained on a single GPU (Nvidia Quadro 4000)of a desktop machine.

Novelty: Applications of convolutional networks to 3D data are still very challenging due to large amount of data and specific requirements to the network architecture. More specifically, the models need to be rotationally and transnationally invariant, which makes classical 2D augmentation tricks loosely applicable here. Thus, new models need to be developed for 3D data.

Title: Semi-supervised representation learning with attention
Problem: training of vector representations using the attention mechanism, thanks to which the quality of machine translation has increased significantly. It is proposed to use it in the encoder-decoder architecture network to obtain vectors of text fragments of arbitrary length.
Data: It is proposed to consider two samples: Microsoft Paraphrase Corpus (a small set of proposals, https://www.microsoft.com/en-us/download/details.aspx?id=52398) and PPDB (a set of short segments, not always correct markup. http://sitem.herts.ac.uk/aeru/ppdb/en/)

Solution: in The problem it is proposed to train vector representations for phrases using the attention and partial learning mechanism. As an internal quality functional, it is proposed to use the improved error function from [2]. As an applied problem, we can consider the problem of detecting paraphrases and sentiment analysis. Moreover, based on the results obtained in [1], it can be assumed that the attention mechanism has a greater influence on obtaining universal vectors for phrases than the network architecture. It is proposed to test this hypothesis using two different architectures - a standard recurrent and feed-forward network.

Title: Selection of Interpreted Multi-Models in Credit Scoring The problems
Problem: The problem of credit scoring is to determine the level of creditworthiness of the borrower. For this, a borrower's questionnaire is used, containing both numerical (age, income) and categorical features (gender, profession). It is required, having historical information about the repayment of loans by other borrowers, to determine whether the borrower will return the loan. The data can be heterogeneous (example, if there are different income regions in a country), and several models will be needed to adequately classify. It is necessary to determine the optimal number of models. Based on the set of model parameters, it is necessary to draw up a portrait of the borrower.
Data: It is proposed to consider five samples from the UCI and Kaggle repositories, with a capacity of 50,000 objects or more.

Title: Generation of features that are invariant to changes in the frequency of the time series.
Problem: Informally: there is a set of time series of a certain frequency (s1), and the information we are interested in is distinguishable and at a lower sampling rate (in the example, the samples occur every millisecond, and the events of interest to us occur at an interval of 0.1 s). These series are integrated reducing the frequency by a factor of 10 (i.e. every 10 values are simply summed) and a set of time series s2 is obtained. be described in the same way. Formally: Given a set of time series s1, .., sNS with a high sampling rate 1. Target information (example, hand movement/daily price fluctuation/…) is distinguishable and at a lower sampling rate 2 < 1. It is necessary to find such a mapping f: S G, - the frequency of the series, that it will generate similar feature descriptions for series of different frequencies. Those.

f* = argminf E(f1(s1) -f2(s2)) , where E is some error function.

Data: Sets of time series of people's physical activity from accelerometers; human EEG time series; time series of energy consumption of cities/industrial facilities. Sample link: UCI repository, our EEG and accelerometer samples.
References: See above for Accelerometers
Base algorithm: Fourier transform.
Solution: Building an autoencoder with a partially fixed internal representation as the same time series with a lower frequency.
Novelty: For time series, there is no “common approach” to analysis, in contrast, in the example, to image analysis. If you look at the problem abstractly, now the cat is defined as well as and the cat, which takes up half the space in the image. An analogy with time series suggests itself. Moreover, the nature of data in pictures and in time series is similar: in pictures there is a hierarchy between values along two axes (x and y), and in time series - one at a time - along the time axis. The hypothesis is that methods similar to image analysis will provide qualitative results. The resulting feature representation can be further used for classification and prediction of time series.

Title: Classification of superpositions of movements of physical activity
Problem: Human behavior analysis by mobile phone sensor measurements: detect human movements from accelerometer data. The accelerometer data is a signal without precise periodicity, which contains an unknown superposition of physical models. We will consider the superposition of models: body + arm/bag/backpack.

Classification of human activities according to measurements of fitness bracelets. According to the measurements of the accelerometer and gyroscope, it is required to determine the type of activity of the worker. It is assumed that the time series of measurements contain elementary movements that form clusters in the space of time series descriptions. (Development: The characteristic duration of movement is seconds. Time series are marked with activity type marks: work, rest. The characteristic duration of activity is minutes. It is required to restore the type of activity by the description of the time series and cluster.)

Title: Creation of ranking models for information retrieval systems. Algorithm for Predicting the Structure of Locally Optimal Models
Problem: It is required to predict a time series using some parametric superposition of algebraic functions. It is proposed not to cost the prognostic model, but to predict it, that is, to predict the structure of the approximating superposition. A class of considered superpositions is introduced, and on the set of such structural descriptions, a search is made for a locally optimal model for the problem under consideration. The problem consists in 1) searching for a suitable structural description of the model 2) describing the search algorithm for the structure that will correspond to the optimal model 3) describing the algorithm for inverse construction of the model according to its structural description. For an already existing example of the answer to questions 1-3, see the works of A. A. Varfolomeeva.
Data:
1. Collection of text documents TREC (!)
2. A set of time series, which implies the restoration of functional dependencies. It is proposed to first use synthetic data or immediately apply the algorithm to forecasting time series 1) electricity consumption 2) physical activity with subsequent analysis of the resulting structures.

Base algorithm: Specifically, there is no basic algorithm for the proposed problem. It is proposed to try to repeat the experiment of A.A. Varfolomeeva for a different structural description in order to understand what is happening.
Solution: The superposition of algebraic functions defines an ortree, on the vertices of which the labels of the corresponding algebraic functions or variables are given. Therefore, the structural description of such a superposition can be its DFS-code. This is a string consisting of vertex labels, written in the order in which the tree is traversed by depth-first search. Knowing the arities of the corresponding algebraic functions, we can restore any such DFS-code in O(n) and get back the superposition of functions. On the set of similar string descriptions, it is proposed to search for the string description that will correspond to the optimal model.

Title: Definition of neural network parameters to be optimized.
Problem: The problem of neural network optimization is considered. It is required to divide the model parameters into two groups:
1. a) Model parameters to be optimized
2. b) Model parameters whose optimization has been completed. Further optimization of these parameters will not improve the quality of the model.

It is proposed to consider the optimization of parameters as a stochastic process. Based on the history of the process, we find those parameters whose optimization is no longer required.

Data: A selection of handwritten MNIST digits
Basic algorithm: Random choice of parameters.

Novelty: The resulting algorithm will significantly reduce the computational cost of optimizing neural networks. A possible further development of the method is to obtain estimates for the parameters of the network obtained from the original operations of expansion, compression, adding and removing layers.

Title: Obtaining likelihood estimates using autoencoders
Problem: it is assumed that the objects under consideration obey the manifold hypothesis (manifold learning) - high-dimensional vectors are concentrated around some subspace of lower dimension. Works [1, 2] show that some modifications of autoencoders are looking for a k-dimensional manifold in the object space, which most fully conveys the data structure. In [2], an estimate of the probability density of data is derived using an autoencoder. It is required to obtain this estimate for the plausibility of the model.

Title: Predict properties and types of atoms in molecular graphs using convolutional networks.
Problem: Multilabel classification using convolutional neural networks (CNN) on graphs.

To predict the interaction of molecules with each other, it is often necessary to correctly describe their constituent atoms by assigning certain types to them. For small molecules, not many descriptors are available: the coordinates and chemical elements of atoms, the lengths of bonds and the magnitude of the angles between them. Using these features, we successfully predict atomic hybridizations and bond types. In this approach, each atom is considered "individually", the information about neighboring atoms necessary to determine the type of an atom is practically not used, and the types of atoms are determined by checking a large number of conditions. At the same time, molecules are represented as 3D molecular graphs, and it would be interesting to use this to predict their types with machine learning methods, for example, using CNNs. It is necessary to predict the types of vertices and edges of molecular graphs:

1. atom type (graph vertex type, about 150 classes),
2. atom hybridization (auxiliary feature, vertex type, 4 classes),
3. connection type (auxiliary feature, edge type, 5 classes).

The type of an atom (graph vertex) is based on information about its hybridization and the properties of neighboring atoms. Therefore, in the case of a successful solution of the classification problem, clustering can be carried out to find other ways to determine the types of atoms.

Data: About 15 thousand molecules represented as molecular graphs. For each vertex (atom), 3D coordinates and a chemical element are known. Additionally, bond lengths, angles and dihedral angles between atoms (3D graph coordinates), binary signs reflecting whether an atom is included in the cycle and whether it is terminal are calculated. The sample is labeled, but the labeled data may contain ~5% errors.

If there is not enough data, it is possible to increase the sample (up to 200 thousand molecules), associated with an increase in inaccuracies in labeling.

References:
Base algorithm: Prediction of hybridizations and link orders using a multiclass non-linear SVM with a small number of descriptors. https://hal.inria.fr/hal-01381010/document
Solution: Proposed solution to the problem and ways of conducting research.

Methods for presenting and visualizing data and conducting error analysis, analyzing the quality of the algorithm. At the first stage, it will be necessary to determine the operations on the graphs necessary to build the network architecture. Next, you will need to train the network for multi-class classification of the types of vertices (and edges) of the input graph. To assess the quality of the algorithm, it is supposed to evaluate the accuracy using cross-validation. For the final publication (in a specialized journal), it will be necessary to make a specific test for the quality of predictions: based on the predicted bond types, the molecule is written as a string (in SMILES format) and compared with a sample. In this case, for each molecule, the prediction will be considered correct only if the types of all bonds in it were predicted without errors.

Novelty: The proposed molecular graphs have a 3D structure and internal hierarchy, making them an ideal CNN application.

Title: Formulation and solution of an optimization problem combining classification and regression to estimate the binding energy of a protein and small molecules. The problem description [78]
Problem:

From the point of view of bioinformatics, The problem is to estimate the free energy of protein binding to a small molecule (ligand): the best ligand in its best position has the \textbf{lowest free energy} of interaction with the protein. (Following a large text, see the file at the link above.)

Data:
1. Data for binary classification.

Approximately 12,000 protein-ligand complexes: for each of them there is 1 native position and 18 non-native ones. The main descriptors are histograms of distributions of distances between different atoms of the protein and ligand, the dimension of the vector of descriptors is ~ 20,000. In the case of continued research and publication in a specialized journal, the set of descriptors can be expanded. The data will be provided as binary files with a python script to read.

1. Data for regression.

For each of the presented complexes, the value of the quantity is known, which can be interpreted as the binding energy.

References:
1. SVM [79]
2. Ridge Regression [80]
3. [81] (section 1)
Base algorithm: [82]

In the classification problem, we used an algorithm similar to linear SVM, whose relationship with the energy estimate, which is outside the scope of the classification problem, is described in the above article. Various loss functions can be used in a regression problem.

Solution: It is necessary to connect the previously used optimization problem with the regression problem and solve it using standard methods. Cross-validation will be used to check the operation of the algorithm.

There is a separate test set consisting of (1) 195 complexes of proteins and ligands, for which it is necessary to find the best ligand pose (the algorithm for obtaining ligand positions differs from that used in training), (2) complexes of proteins and ligands, for which native poses it is necessary to predict the energy binding, and (3) 65 proteins for which the most strongly binding ligand is to be found.

Novelty:' First of all, the interest is combining classification and regression problems.

The correct assessment of the quality of protein and ligand binding is used in drug development to search for molecules that interact most strongly with the protein under study. Using the classification problem described above to predict the binding energy results in an insufficiently high correlation of predictions with experimental values, while using the regression problem alone leads to overfitting.

Title: Construction of an approximating description of a scalogram in the problem of predicting movements using an electrocorticogram.
Problem: As part of solving the problem of decoding ECoG signals, The problem of classifying movements by time series of electrode readings is solved. The tools for extracting features from ECoG time series are the coefficients of the wavelet transform of the signal under study [Makarchuk 2016], on the basis of which a scalogram is built for each electrode - a two-dimensional array of features in frequency-time space. Combining scalograms for each electrode gives signs of a time series in the spatio-frequency-time domain. The feature description constructed in this way obviously contains multicorrelated features and is redundant. It is required to propose a method for reducing the dimension of the feature space.
Data: Measurements of the positions of the fingers when performing simple gestures. Description of experiments data.

Title: Multiple Manifold Learning (Joint diagonalization for 3D shapes - AJD on Hessian matrices).
Problem: Building an optimal algorithm for the Multiple Manifold Learning The problem. Two protein conformations (two tertiary structures) are given. In the vicinity of each state, a model of an elastic body is specified (oscillations of the structure in the vicinity of these states). The problem is to build a general model of an elastic body to find intermediate states with the maximum match with these models in the vicinity of given conformations. The space of motion of an elastic body is given by the Hessian eigenvectors. It is required to find a common low-rank approximation of the space of motions of two elastic bodies.
Data: Protein structures in double conformations from PDB, about 100 sets from the article https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4677049/
References: A list of scientific papers, supplemented by 1) the statement of the problem being solved, 2) links to new results (a recent article that is close in results), 3) basic information about the problem under study.

Novelty: Using simple elasticity models with one or more free parameters, thermal fluctuations in proteins can be described. However, such models do not describe transitions between several stable conformations in proteins. The purpose of this work is to refine the elastic model so that it also describes the space of conformational changes.

Title: Convex relaxations for multiple structure alignment (synchronization problem for SO(3)).
Problem: Find transformations to align protein tertiary structures simultaneously (in simple words: find orthogonal transformations that align data in R^3 molecules that have the same chemical formula). If the structures are the same (the RMSD is equal to zero after alignment, the structures are aligned exactly), then you can align in pairs. However, if this is not the case, then the Basic algorithm, generally speaking, does not find the optimum of the original problem with a loss function for simultaneous equalization.
Data: Protein structures in PDB format in various states and coordinate systems.

Title: Adaptive relaxations of NP hard problems through machine learning
Problem: Modern problems of optimizing power flows in power networks lead to non-convex optimization The problems with a large number of restrictions. Statements similar in structure also arise in a number of other engineering problems and in classical The problems of combinatorial optimization. The traditional approach to solving such NP hard problems is to write their convex relaxations (semidefinite/SDP, second order conic/SOCP, etc), which usually have a much larger set of feasible solutions than in the original problem. and by the subsequent projection of the obtained solution into the region where the constraints of the original problem are satisfied. In many practical cases, the quality of the solution obtained in this way is not high. Alternative approaches, for example MILP (mixed integer linear programming) relaxation, are substantially more time consuming but result in a more accurate answer.

The main problem is the impossibility of using known methods for solving large-scale problems (networks of 1000 nodes and more). One of the key obstacles is not so much the dimension of the problem as a large number of restrictions. At the same time, in real The problems it is possible to single out a small set of restrictions such that the sets of admissible points in the selected set and in the original one are very close. This will allow us to replace The problem with another one with fewer restrictions, which will increase the speed of the algorithms used. It is proposed to use machine learning methods to build the indicated set of the most important constraints.

Title: Optimal Algorithm for Reconstruction of Dynamic Models.
Problem: A standard machine learning problem statement in the context of unsupervised learning assumes that the examples are independent and come from the same probability distribution. However, often observed data are of dynamic origin and are correlated. The problem is to develop an efficient method for restoring a dynamic graphical model (graph and model parameters) from observed correlated dynamic configurations. This The problem is theoretically important and has many applications. The basis of the algorithm will be the adaptation of a new optimal method of screening interactions (interaction screening), developed for the Ising model. The solution process will combine familiarity with computer science/machine learning theoretical methods and numerical experiments.
Data: Simulated dynamic configurations of spins in the kinetic Ising model.

Title: Choice of Interpreted Multimodels in Credit Scoring The problems
Problem: The problem of credit scoring is to determine the level of creditworthiness of the borrower. For this, a borrower's questionnaire is used, containing both numerical (age, income) and categorical features (gender, profession). It is required, having historical information about the repayment of loans by other borrowers, to determine whether the borrower will return the loan. The data can be heterogeneous (example, if there are different income regions in a country), and several models will be needed to adequately classify. It is necessary to determine the optimal number of models. Based on the set of model parameters, it is necessary to draw up a portrait of the borrower.

Title: Thematic modeling of an economic sector based on bank transaction data.
Problem: Test the hypothesis that a large sample of transactions between firms is adequately described by a relatively small set of economic activities (aka topics). The problem is reduced to decomposing the matrix of transactional data "buyers × sellers" into the product of three non-negative matrices "buyers × topics", "topics × topics", "topics × sellers", while the middle matrix describes a directed graph of financial flows in the industry. It is required to compare several methods for constructing such expansions and find the number of topics for which the observed set of transactions is modeled with sufficient accuracy.
Data: selection of transactions between firms, such as "buyer, seller, volume".

Title: Generating and selecting features when building a credit scoring model.
Problem: Credit scoring models are built step by step. In particular, a number of independent transformations of individual features are performed, and new features are generated. Each step uses its own quality criterion. It is required to build a scoring model that adequately describes the sample. Maximizing the quality of the model at each step does not guarantee the maximum quality of the resulting model. It is proposed to abandon the step-by-step construction of the scoring model. To do this, the quality criterion must include all the optimized parameters of the model.
Data: The computational experiment will be performed on 5-7 samples to be found. It is desirable that the samples be of the same nature, for example, the samples of consumer credit questionnaires.

Title: Optimal algorithm for recovering block Hamiltonians (XY and Heisenberg models).
Problem: The problem is to reconstruct block Hamiltonians with continuous spins (a generalization of the Ising model to two- and three-dimensional spins) from the observed data. This setting is a special case of a field of machine learning known as unsupervised learning. Reconstruction of a graphical spin model from observational data is an important problem in physics. The basis of the algorithm will be the adaptation of a new optimal method of screening interactions (interaction screening), developed for the Ising model. The solution process will combine familiarity with computer science/machine learning theoretical methods and numerical experiments.
Data: Simulated block spin model configurations.

Title: Estimated binding energy of protein and small molecules.
Problem: Modeling the binding of a protein and a small molecule (hereinafter referred to as a ligand) is based on the fact that the best ligand in its best position has the lowest free energy of interaction with the protein. It is necessary to estimate the free energy of protein and ligand binding. Complexes of proteins with ligands can be used for training, and for each protein there are several positions of the ligand: 1 correct, "native", for which the energy is minimal, and several generated incorrect ones. For a third of the data set, values are known that are proportional to the desired binding energy of ligands in native positions with the protein. There is a separate test set consisting of 1) complexes of proteins and ligands, for which it is necessary to find the best ligand position (the algorithm for obtaining ligand positions differs from that used in training), 2) complexes of proteins and ligands, for whose native positions it is necessary to predict the binding energy, and 3) proteins for which it is necessary to find the most strongly binding ligand.
Data: About 10000 complexes: for each of them there is 1 native pose and 18 (more can be generated) non-native ones. The main descriptors are histograms of distributions of distances between different atoms of the protein and ligand, the dimension of the vector of descriptors is ~ 20,000. The set of descriptors can be extended (you can generate poses with different deviations and use it as a descriptor, you can add the properties of small molecules: the number of bonds around which rotation is possible in a molecule, its surface area, its surface division by a Voronoi diagram. The data will be provided in the form of binary files with a python script to read.
References: PEPSI-Dock: a detailed data-driven protein–protein interaction potential accelerated by polar Fourier correlation Predicting Binding Poses and Affinities in the CSAR 2013―2014 Docking Exercises Using the Knowledge-Based Convex-PL Potential
Base algorithm: We used a linear SVM (these are just lecture notes, I see no reason to give Vapnik here, especially since all this, including these lecture notes, is googled), the connection of which with an energy estimate that goes beyond scope of the classification The problem is described in the articles listed above. To take into account experimentally known values proportional to energy, it is proposed to use linear regression SVR .
Solution: It is necessary to reduce the previously used SVM problem to a regression problem and solve it using standard methods. To check the operation of the algorithm, both the test described above and several other test sets with similar The problems but different data will be used.
Novelty: Proper assessment of the quality of protein and ligand binding is used in drug development to find molecules that interact most strongly with the protein under study.

Of particular importance is the assessment of the values of the binding energy of the protein with the ligand: the coefficient of correlation (Pearson) of the energy with its experimental values determined by different groups on the proposed test does not exceed 0.7. Prediction of the most strongly binding ligand from a large number of non-protein-binding molecules is also difficult. The aim of this work is to obtain a method that allows a fairly accurate assessment of protein binding to ligands. From the point of view of machine learning and optimization, it is of interest to combine classification and regression problems.

Appendix Given several data sets describing an atom in a molecule or a bond between atoms, with a small feature vector (usually 3-10 descriptors) and several classes corresponding to the atom's hybridization or bond order. The data itself can be from ~100 to 20,000 vectors depending on the type of atom. You need to test some kind of multiclass machine learning on this (random forests, neural network, something else), you can do anything with descriptors. We are currently using SVM. Not only the accuracy is important, but also the computational complexity of the prediction.

Title: Creation of delay-operators for multiscale forecasting by means of symbolic regression
Problem: Suppose that one needs to build a forecasting machine for a response variable. Given a large set of time series, one can advance a hypothesis that they are related to this variable. Relying upon this hypothesis, we can use given time series as features for the forecasting machine. However, the values of time series could be produced with different frequencies. Therefore, we should take into account not only the values, but the delays as well. The simplest model for forecast is a linear one. In the presence of large set of features this model can approximate the response quite well. To avoid the problem of multiscaling, we introduce a definition of delay-operators. Each delay-operator corresponds to one time series and represents continuous correlation function. This correlation function shows a dependence between the response variable and corresponding time series. Therefore, each delay-operator put weights on the values of corresponding time series depending on the greatness of the delay. Having these delay-operators, we avoid the problem of multiscaling. To find them, we use genetic programming and symbolic regression. If the resulted weighted linear regression model would produce poor approximation, we can use a nonlinear one instead. To find good nonlinear function, we would use symbolic regression as well.
Data: Any data from the domain of multiscalse forecating of time series. See the full version of this introduction.

Data: Synergy of classification algorithms. Data from the UCI repository so that it can be compared directly with other works, in particular the work of Vapnik.
References: There are different approaches to combining SVMs: on example, bagging (http://www.ecse.rpiscrews.us/~cvrl/FaceProject/Homepage/Publication/ICPR04_final_cameraready_v4.pdf), also try and boosting (http://www.researchgate.net/profile/Hong-Mo_Je/publication/3974309_Pattern_classification_using_support_vector_machine_ensemble/links/09e415091bdc559051000000.pdf).
Base algorithm: Described in the problem statement
Solution: a modification of the basic algorithm, or simply the Basic algorithm itself. The main thing is to compare with other methods and draw conclusions, in particular, about the relationship between the presence of an improvement in the quality and diversity of sets of reference objects built by different SVMs.
Novelty: It is known (for example, from Konstantin Vyacheslavovich's lectures) that it is not possible to build short compositions from strong classifiers (for example, SVM) using boosting (although they still try (see literature)). Therefore, it is proposed to build a nonlinear combination instead of a linear one. It is assumed that such a composition can give an increase in quality compared to a single SVM.

Title: Coordination of logical and linear classification models in the information analysis of electrocardiosignals.
Problem: There are logical classifiers based on the identification of diagnostic standards for each disease and built by the Expert in semi-manual mode. For these classifiers, estimates of disease activities are determined, which have been used in the diagnostic system for many years and satisfy physician users. We build linear classifiers that are trained completely automatically and are ahead of logical classifiers in terms of classification quality. However, a direct transfer of the activity estimation technique to linear classifiers turned out to be impossible. It is required to build a linear activity model, setting it to reproduce the known activity estimates of the logical classifier.

Title: Thematic classification model for diagnosing diseases by electrocardiogram.
Problem: Technology of information analysis of electrocardiosignals according to V.M.Uspensky is based on ECG conversion into a character string and selection of informative sets of words - diagnostic standards for each disease. The linear classifier builds one diagnostic standard for each disease. The Screenfax screening diagnostic system now uses four standards for each disease, built in a semi-manual mode. It is required to fully automate the process of constructing diagnostic standards and to determine their optimal number for each disease. To do this, it is supposed to finalize the thematic classification model of S. Tsyganova, to perform a new implementation under BigARTM, to expand computational experiments, to improve the quality of classification.
Data: A selection of more than 10 thousand electrocardiograms with diagnoses for 32 diseases.

Title: Thematic models of distributive semantics for highlighting ethno-relevant topics in social networks.
Problem: Thematic modeling of social media text collections faces the problem of ultra-short documents. It is not always clear where to draw the boundaries between documents (possible options: a single post, a user's wall, all posts by a given user, all posts for a given day in a given region, and so on). Topic models give interpretable vector representations of words and documents, but their quality depends on the distribution of document lengths. The word2vec model is independent of document lengths, since it takes into account only the local contexts of words, but the coordinates of vector representations do not allow thematic interpretation. The objective of the project is to build a hybrid model that combines the advantages and is free from the disadvantages of both models.
Data: Collections of social networks LJ and VK.
References: will issue :)
Base algorithm: Topic models previously built on this data.
Solution: Implementation of a distributive semantics regularizer similar to the vord2vec language model in the BigARTM library.
Novelty: So far, there are no language models in the literature that combine the main advantages of probabilistic topic models and the word2vec model.

Title: Building scoring models in the SAS system (or MATLAB).
Problem: Describe the main steps in building scoring models. At the stage of data preparation, The problem of filtering choices (removing noise objects) is solved. Since the sample contains a significant number of features that do not correlate with solvency, it is necessary to solve the problem of feature selection. In addition, due to the heterogeneity of the data (by example, by region), it is proposed to build a mixture of models, in which each model describes its own subset of the sample. At the same time, different sets of features can correspond to different components of the mixture.

Title: Approximation of combinatorial overfitting estimates for feature selection in the problem of medical diagnostics.
Problem: Technology of information analysis of electrocardiosignals according to V. M. Uspensky is used to diagnose diseases of internal organs by electrocardiogram. The linear naive bayesian classifier with feature selection performs well in this The problem. However, only very simple greedy strategies have been used so far for feature selection. It is proposed to use more intensive enumeration strategies to find better and shorter diagnostic feature sets. However, the more intense the search, the higher the probability of overfitting. To reduce overfitting, it is proposed to use combinatorial estimates of overfitting of threshold decision rules. For efficient calculation of these estimates, it is proposed to use surrogate modeling.
Data: Samples of vectors of ECG feature descriptions obtained using the Screenfax screening diagnostics system. Will be issued.

Title: Algorithm for predicting the structure of locally optimal models
Problem: It is required to predict a time series using some parametric superposition of algebraic functions. It is proposed not to cost the prognostic model, but to predict it, that is, to predict the structure of the approximating superposition. A class of considered superpositions is introduced, and on the set of such structural descriptions, a search is made for a locally optimal model for the problem under consideration. The problem consists in 1) searching for a suitable structural description of the model 2) describing the search algorithm for the structure that will correspond to the optimal model 3) describing the algorithm for inverse construction of the model according to its structural description. For an already existing example of the answer to questions 1-3, see the work of A. A. Varfolomeeva.
Data: A set of time series, which implies the restoration of functional dependencies. It is proposed to first use synthetic data or immediately apply the algorithm to forecasting time series 1) electricity consumption 2) physical activity with subsequent analysis of the resulting structures.

Base algorithm: Specifically, there is no basic algorithm for the proposed problem. It is proposed to try to repeat the experiment of A. A. Varfolomeeva for a different structural description in order to understand what is happening.
Solution: The superposition of algebraic functions defines an ortree, on the vertices of which the labels of the corresponding algebraic functions or variables are given. Therefore, the structural description of such a superposition can be its DFS-code. This is a string consisting of vertex labels, written in the order in which the tree is traversed by depth-first search. Knowing the arities of the corresponding algebraic functions, we can restore any such DFS-code in O(n) and get back the superposition of functions. On the set of similar string descriptions, it is proposed to search for the string description that will correspond to the optimal model.

Base algorithm: Use the variational method for constructing mappings, which was previously proposed for constructing spatial mappings with a given boundary mapping [4], [5], in the case when a measure of proximity of functions describing geometric bodies is given on example , as an rms measure of the proximity of brightness functions.
Solution: For the existing code that implements the variational method for constructing two-dimensional mappings with minimal distortion, it is necessary to add a module that implements an additive to the functional, which is a measure of the proximity of geometric bodies.

Title: Stability of sampling of electrocardiosignals relative to frequency filtering.
Problem: Technology of information analysis of electrocardiosignals according to V.M.Uspensky is based on the transformation of the electrocardiogram into a character string (codogram) and the selection of informative sets of words - diagnostic standards for each disease. The problem is that for discretization it is necessary to accurately determine the amplitude of the R-peaks. The amplitude can be affected by the frequency filtering of the signal, which is performed by the electrocardiograph at the hardware or software level. The problem is to evaluate how much different frequency filters (example, 50.4Hz mains suppression filter, high-pass filter) can affect the word frequencies in the codegram and the quality of the classification.
Data: electrocardiograms in KDM format.
References: will issue :)
Base algorithm: Linear classifier.
Solution: Direct and inverse Fourier transform, algorithm for detecting R-peaks on an electrocardiogram, algorithm for determining the amplitude of R-peaks.
Novelty: The study of the stability of codograms in relation to frequency filtering with different parameters has not previously been carried out in the information analysis of electrocardiosignals.

Title: Improving the quality of demand forecasting using product groups
Problem description:

Given:

1. Time series of sales for several product groups in one hypermarket. Also, for each product, periods of shortage, periods of influence on the demand of calendar holidays and periods of holding are known. marketing promotions. A product classifier is also known: a tree of product groups, where the products themselves are leaves.
2. Forecasting algorithm that is used to generate demand forecasts for these products: self-adaptive exponential smoothing (Trigg-Leach model, see [1])
3. Loss function by which the quality of forecasts is measured: MAPE.
4. Requirements for building forecasts: forecasts must be built weekly for 4 weeks ahead (at the beginning of the current week, you need to build a forecast of total demand for the next week, a week in one, two, and 3).

Hypothesis: Demand for individual goods is too volatile to reveal their characteristic seasonality. It is proposed to use data on product groups in order to more accurately determine the parameters of seasonality. Note: there are other options for improving the quality of forecasting by working with groups of goods. The problem is to improve the quality of forecasting within the framework of The problem by taking into account the effect of the interchangeability of goods, in comparison with the Basic algorithm The result can be considered achieved if a statistically significant increase in quality is shown when building a series of forecasts (at least 20) for each time series using a sliding control.

Base algorithm: It is proposed to use the seasonality model [3] in combination with the Trigg-Leach model as a non-seasonal series prediction algorithm ([1] and [2]). In this case, 3 variants of the algorithm are possible, depending on the method of assessing seasonality:
1. Seasonality is estimated by the very series of sales. For products with a "short" history, seasonality is not assessed.
2. Seasonality is estimated for a group of goods, based on the classifier of commodity groups (lower level of the classifier)
3. Seasonality is estimated by clusters, based on the methodology [3], [4].
Solution: It is required to implement the combination of the seasonality model [3] and the Trigg-Leach model as a non-seasonal series prediction algorithm ([1] and [2]), with the 3 variants of seasonality analysis described above. When constructing seasonal profiles, it is necessary to exclude periods of marketing campaigns (otherwise, there may be a significant distortion of seasonality). Next, you need a series of experiments with quality analysis on real data. When analyzing quality, you can exclude periods of holidays and marketing campaigns. Based on the results of the experiments, it may be necessary to adapt the clustering algorithm.
Novelty: Building a self-adaptive forecasting algorithm taking into account seasonality, identified by cluster analysis.

Title: Prediction of Quaternary Structures of Proteins: нивелирование
Problem description: The problem is to predict the packing of protein molecules into a multimeric complex in the rigid body approximation. One of the formulations of the problem is written as a non-convex optimization.

It is necessary to study this formulation and propose a solution algorithm. Suppose we have $N$ proteins in an assembly, such that each protein $i$ can be located in one of $P$ positions $x_{p}^{i}$ . $N$ is ~ 10, $P$ ~ 100. To each two vectors $x_{i}^{p}$ and $x_{j}^{q}$ , we can assign an energy function $q_{0}$ , which is the overlap integral in the simplest approximation. Each protein position also has an associated score $b_{0}$ .

Data: Collected using one of the standard complexes resolved using electron microscopy. The energy values and overlap integrals are calculated by modifying one of the standard packages, on example, HermiteFit. Data is generated in ~1 minute, code modification and data preparation will take ~1 week.

Title: Checking the compliance of the electrocardiograph with the requirements of the diagnostic system "Screenfax" and assessing the quality of electrocardiograms.
Problem description: The problem of checking the compliance of an arbitrary electrocardiograph with the requirements of the "Screenfax" diagnostic system [1—4] is solved based on a comparison of electrocardiograms (ECG) of the same and the same patients recorded by both devices according to the ABAB scheme, where A is the first device, B - the second. The problem of automatic detection of low-quality electrocardiograms that do not meet the requirements of the diagnostic system is also solved.
Data: The selection consists of records with ECG values recorded by the device for which the test is being carried out, and by the device used in the Screenfax diagnostic system (data with a detailed description of the recording format will be provided to the person who selected The problem). You can use http://www.physionet.org/physiobank/database/ptbdb/ to test algorithms for R-peak detection and noise level estimation.

Base algorithm: ECG quality estimation – [4], R-peak detection – [5], noise level estimation in data – [6].
Solution: The problem of checking the compliance of an arbitrary electrocardiograph with the requirements of the "Screenfax" diagnostic system is proposed to be solved by constructing permutation statistical tests by comparing the values of RR-intervals and R-amplitudes and detected code sequences (calculated by amplitudes and intervals) for each diseases. This is where The problem of detecting R peaks comes in. In The problem of detecting low-quality electrocardiograms, The problem of estimating the noise level arises. In addition, it is necessary to learn how to filter out ECG with non-informative amplitude values or a large spread of interval values, since the method of analyzing electrocardiographic signals is not applicable to the diagnosis of arrhythmia.
Novelty: The problem of checking the compliance of the electrocardiograph with the requirements of the diagnostic system can be considered as The problem of comparing ECG recording devices that arise, for example, when comparing different types of electrodes, and the noise level in the values of electrocardiosignals, the presence of baseline drift are selected as criteria and some other features [7].

Title: Simplification of the IR models structure
Problem: To achieve the acceptable quality of the information retrieval models, modern search engines use models of very complex structure. In current research we propose to simplify the model structure and make it interpretable without decreasing the model accuracy. To do this, we follow the idea from (Goswami et al., 2014) of constructing the set of nonlinear IR functions of simple structure and admissible accuracy. However, each of these functions is expected to have lower accuracy while comparing with the best IR model of complex structure. Thus, we propose to approximate this complex model with the linear combination of simple nonlinear functions and expect to obtain the comparable quality of solution.
Data: TREC collections.

Title: Testing non-parametric time series forecasting algorithms under non-stationary conditions
Problem: One of the key assumptions about the distribution of data in non-parametric is the assumption that the time series is stationary. The adequacy of forecasts if this requirement is not met is not guaranteed. It is required to develop a method for determining the fulfillment of the condition of local stationarity of the time series to study the applicability of the main algorithms of nonparametric forecasting in the absence of stationarity. Consider the main methods of nonparametric regression, such as kernel smoothing, spline smoothing, autoregression, moving average, etc.

Title: Building a hierarchical topic model of a large conference
Problem: Every year, the program committee of a major EURO conference (more than 2000 reports) is faced with The problem of building a hierarchical model of conference abstracts. Due to the fact that the structure of the conference changes little from year to year, it is proposed to build a thematic model of the future conference using expert models of conferences of previous years. This raises the following subThe problems:

Classification of abstracts of the new conference.
Predicting changes in the structure of the conference.

Data: Abstracts and expert models of EURO 2010, 2012, 2013 conferences.

Title: Regularization of the linear naive bayes classifier.
Problem: Building a linear classifier is one of the classic and most well studied machine learning The problems. A linear naive bayesian (LNB) classifier has the strong advantage that it builds in time that is linear in sample length, and the strong limitation that it assumes that the features are independent in its derivation. On some data, LNB performs surprisingly well, despite a clear violation of the feature independence hypothesis. The Linear Support Vector Machine (SVM) is considered to be a very successful method, but takes a long time on large samples. Both of these methods work in the same space of linear classifiers. The idea of the study is to bring LNB closer to SVM in terms of quality, but without loss of efficiency, by means of minor corrections.
Data: One of the three data sets, optional: classification of texts into scientific and non-scientific, classification of abstracts by fields of science, classification of ECG codograms for sick and healthy.

Base algorithm: any ready-made LNB and SVM implementations. Plus naive feature selection for LNB.
Solution: Derive correction formulas for LNB weights when using a margin-maximization regularizer similar to SVM. We build an iterative process in which a correction is calculated at each step, bringing the LNB closer to the SVM a little more. ROC-curves and dependences of Hold-out AUC on the iteration number are built.
Novelty: The ML community still hasn't realized that any linear classifier is equivalent to some kind of Naive Bayesian classifier.

Title: Thematic model of the interests of regular users of the mobile application.
Problem: The mobile app for learning English words offers the user words one by one. The user can either add a word to the studied ones, or discard it. To start learning words, you need to type at least 10 words. It is required to build a probabilistic word generation model that adapts to the interests of the user.
Data: There are lists of added and dropped words for each user. In addition, it is intended to use a large external collection of texts, for example, Wikipedia, for sustainable topic definition.
References:

Base algorithm: Random word selection algorithm.
Solution: The topic model for each user determines the topic profile of his interests p(t|u). To generate words, word distributions from the distributions p(w|t) of the topics of the given user are used. Dependences of the quality functionals of the thematic model on the iteration number are constructed. The main functionality of quality is the ability of the model to predict which words the user will leave and which ones they will discard.
Novelty: A feature of the model is the presence of discarded words. The developed methods can also be applied in recommender systems with likes and dislikes.

Optimizing the Number of Topics in Probabilistic Topic Models with a String Sparse Regularizer

Problem: The probabilistic topic model describes the probabilities of occurrence of words $w\in W$ in documents $d\in D$ through latent topics $t\in T< /text>: <tex> p(w|d) = \sum_{t\in T} p(w|t)p(t|d) = \sum_{t\in T} \phi_{wt}\theta_{td}.$ We need to test the hypothesis that by imposing constraints on the $\Theta$ matrix using the string sparse regularizer, it is possible to determine the optimal number of topics.

Data: The collection of documents is specified by word frequencies. Since to solve the problem it is necessary to know the <<true>> number of topics, experiments are performed on realistic model or semi-model data.

Novelty: Dirichlet's HDP [2006: Teh et Al] hierarchical process model is commonly used to optimize the number of topics. It determines the number of topics is unstable, and at the same time it is difficult both to understand and to implement. Additive Regularization of Topic Models (ARTM) is a new approach to topic modeling that combines versatility, flexibility and simplicity. The problem of optimizing the number of topics has not yet been considered in the framework of ARTM.

Differential diagnosis of diseases by electrocardiogram
Problem: It is proposed to solve a typical classification problem. Signs are 216 characteristics calculated from the electrocardiogram. It is necessary to evaluate the quality of the classification on a delayed control sample. To do this, the fractions of errors of the first and second kind are calculated. Under the error of the first kind is meant the assignment of healthy people to the class of patients, the second kind - the assignment of patients to the class of healthy people. Preference is given to minimizing Type II errors.
Data: For each of the 5 diseases, there are 2 types of samples. Reference - more reliable, specially selected cases. The rest are cases when the diagnoses were established by doctors less reliably; these samples are proposed to be used for control.

Influence of sparse, smoothing and decorrelation regularizers on the stability of a probabilistic topic model
Problem:Probabilistic topic model describes the probabilities of occurrence of words $w\in W$ in documents $d\in D$ through latent topics $t\in T< /text>: <tex> p(w|d) = \sum_{t\in T} p(w|t)p(t|d) = \sum_{t\in T} \phi_{wt}\theta_{td}.$ Matrix representation $\|p(w|d)\|_{W\times D}$

as a product of two smaller matrices ${\Phi=\|\phi_{wt}\|_{W\times T}}$ and ${\Theta=\|\theta_{dt} \|_{T\times D}}$ is not the only one: $\Phi \Theta = (\Phi S)(S^{-1}\Theta) = \Phi'\Theta'$ for some non-degenerate $S$ . It is required to test the hypothesis that, by imposing restrictions on the matrices $\Phi, \Theta$ using regularizers, it is possible to increase the stability of their recovery.

Data: The collection of documents is specified by word frequencies. To solve the problem, it is necessary to know the “true” matrices $\Phi, \Theta,$ experiments are performed on realistic model or semi-model data that satisfy the hypotheses of sparseness, weak correlation of topics and the presence of background topics.

Detecting Patterns in a Set of Time Series by Structural Learning Methods
consultant: A. P. Motrenko
Problem: To improve the quality of the time series forecast, I would like to use expert statements about the presence of a causal relationship between events. To do this, it is necessary to be able to assess the reliability of expert statements. It is impossible to prove the existence of a causal relationship by statistical methods. The researcher can only check the presence of a certain structure of communication. The purpose of The problem is, based on expert statements about the presence of a connection between events, to examine the time series for the presence of various structural connections and find the structure that is most consistent with the Expert's opinion.

consultant: A. P. Motrenko
Problem: (As part of a study devoted to the discovery of patterns in time series sets) It is proposed to abandon the standard assumptions about the stationarity of the time series when searching for dependencies between time series and to study time series from the point of view of dynamical systems theory, within which irregular time dependences determined by the structure of the phase space are considered. It is required to study a set of approaches to the analysis of dynamic data and the identification of relationships between them; describe the limits of applicability of the basic algorithm and propose new options for the revealed structural relationships.

Building predictive models as superpositions of expert-specified functions
consultant: Ivkin Nikita
Problem: Required to assign a set of time series to one of several classes. It is proposed to do this using the automated feature generation procedure. To do this, Expert creates a set of generating functions that 1) transform the time series (by example, smooth, decompose into principal components), 2) extract its aggregated descriptions from the time series (by example, mean, variance, number of extrema). It is possible to generate a significant number of features by constructing superpositions of generating functions. The resulting features are used to classify a set of time series (for example, by the nearest neighbor method).

Interpretation of multimodels in the processing of sociological data
consultant: Alexander Aduenko
Problem: The problem of credit scoring is to determine the level of creditworthiness of the borrower who applied for a loan. To do this, a borrower's questionnaire is used, containing both numerical data (age, income, time of residence in the country) and categorical features (gender, profession). It is required, having historical information on loan repayments by other borrowers, to determine whether the client in question will return the loan. Thus, it is required to solve the problem of classification. Since the data can be heterogeneous (for example, if there are different income regions in the country), the data can be described not by one, but by several models. In this paper, we propose to compare two methods for constructing multimodels: mixtures of logistic models and gradient boosting.
Data: data on consumer loans (\mlalgorithms\BSThesis\Aduenko2013\data).

Identification of a person by the image of the iris
consultant: Matveev I. A.
Problem: In the problem of identifying a person by the image of the iris (iris), the most important role is played by the selection of the region of the iris in the original image (segmentation of the iris). However, the iris image is usually partially obscured (shaded) by eyelids, eyelashes, highlights, that is, part of the iris cannot be used for recognition and moreover, the use of data from shaded areas can generate false signs and reduce accuracy. Therefore, one of the important steps in the segmentation of the iris image is the rejection of shaded areas.
Data: bitmap monochrome image, typical size 640*480 pixels (however, other sizes are possible) and coordinates of centers and radii of two circles approximating pupil and iris.

Local prediction methods with choice of transformation
Time series forecasting problems have many applications in various fields such as economics, physics, and medicine. Their solution is a forecast for the near future based on the already known values of the predicted series at previous points in time. In the work, a local forecasting algorithm will be built taking into account transformations, which allows, without human intervention, to identify visually similar sections of the time series.

Non-parametric forecasting: kernel selection, parameter tuning
The paper describes the method of nuclear smoothing of the time series, as one of the types of nonparametric regression. The essence of the method

consists in restoring the function of time as a weighted linear combination of points from some neighborhood. A continuous bounded symmetric real weight function is called a kernel. The resulting kernel estimate is used to predict the next point in the series. The dependence of the quality of prediction on the parameters of the kernel and the superimposed noise is investigated.

2. 2011

Exponential Smoothing and Prediction
The paper investigates the application of the exponential smoothing algorithm to time series forecasting. The algorithm is based on taking into account the previous values of the series with weights decreasing as you move away from the studied section of the time series. The behavior of the algorithm on model data in various models of weights is studied. An analysis of the operation of the algorithm on real data - stock indices was carried out.

3. 2011

Isolation of the periodic component of the time series
The project examines the time series for the presence of a periodic component, builds a trigonometric interpolation of the proposed time series using the least squares method. The parameters of the function of the least squares method are estimated depending on the quality of forecasting. In a computational experiment, the results of the work of the correlation function and the least squares method on a noisy model sine and a real time series of an electrocardiogram are presented.

Multivariate caterpillar, choice of length and number of caterpillar components (comparison of smoothed and unsmoothed time series)
The paper describes the caterpillar method and its application for time series forecasting. The algorithm is based on the selection of its informative components from the studied time series and the subsequent construction of a forecast. The dependence of the accuracy of forecasts on the choice of the caterpillar length and the number of its components is investigated. In a computational experiment, the results of the algorithm's operation on periodic series with different patterns within a period, on series with violation of periodicity, as well as on real time series of hourly temperature, are presented.

Prediction by Discrete Argument Functions
The paper investigates short time series on the example of monophonic musical melodies. There is a prediction of one note by exponential smoothing, a local method, as well as a method of searching for constant patterns. The computational experiment is carried out on two melodies, one of which has exactly repeating fragments.

Local forecasting methods, search for metrics
The time series is divided into separate sections, each of which is associated with a point in the n-dimensional feature space. The local model is calculated in three successive stages. The first one finds the k-nearest neighbors of the observed point. The second one builds a simple model using only these k neighbors. The third - using this model, predicts the next one based on the observed point. Many researchers use the Euclidean metric to measure distances between points. This work is intended to compare the accuracy of forecasting when using different metrics. In particular, it is required to investigate the optimal set of weights in the weighted metric to maximize the prediction accuracy.

8. 2011

Local prediction methods, search for invariant transformation
The project uses local forecasting methods time series. There is no temporary representation in these methods series in the class of given functions of time. Instead, the prediction is made on the basis of data about some part of the time series (local information is used). In this paper, we study in detail the following method (a generalization of the classical "nearest neighbour").
Let there be a time series and The problem should continue it. It is assumed that such a continuation is determined

prehistory, i.e. in a series you need to find the part that after some transformation of A becomes similar to the part we are trying to predict. Finding such a transformation A and is the goal of this project. To determine the degree of similarity, the function B is used - the function of the proximity of two segments time series. This is how we find the closest neighbor to our backstory. In general, we are looking for several nearest neighbors. The continuation will be written as their linear combination.

Time Series Flattening: Forecasting with DTW
Time series is a sequence of time-ordered values of some real variable $\mathbf{x}=\{x_{t}\}_{t=1}^T\in\mathbb{R }^T$ . The problem that accompanies the appearance of time series is the comparison of one data sequence with another. Comparison of sequences is greatly simplified after the deformation of the time series along one of the axes and its alignment. Dynamic time warping (DTW) is a technique for effectively leveling time series. DTW methods are used in speech recognition, information analysis in robotics, industry, medicine and other areas.
The purpose of the work is to give an example of alignment, to introduce a comparison functional for two time series, which has the natural properties of commutativity, reflexivity and transitivity. The functional should take two time series as input, and at the output give a number characterizing the degree of their "similarity".

Choosing an Activation Function for Predicting Neural Networks
The aim of the project is to study the dependence of the quality of prediction by neural networks without feedback (single- and multilayer perceptrons) on the chosen activation function of neurons in the network, as well as on the parameters of this function.
The result of the project is to evaluate the quality of forecasting by neural networks depending on the type and parameters of the activation function.

Investigation of Convergence in Prediction by Neural Networks with Feedback
The dependence of the convergence rate in time series forecasting on the parameters of a neural network with feedback is investigated. The concept of feedback is typical for dynamic systems in which the output signal of some element of the system affects the input signal of this element. The output signal can be represented as an infinite weighted the sum of the current and previous input signals. The Jordan network is used as a neural network model. It is proposed to investigate the rate of convergence depending on the choice of the activation function (sigmoid, hyperbolic tangent), on the number of neurons in the intermediate layer and on the width of the sliding window. We also explore a way to increase the rate of convergence using the generalized delta rule.

Multidimensional caterpillar, choice of length and number of caterpillar components
The work is devoted to the study of one of the methods for analyzing multivariate time series - the "caterpillar" method, also known as Singular Spectrum Analysis or SSA. The method can be divided into four stages - the representation of the time series in the form of a matrix using a shift procedure, the calculation of the covariance matrix of the sample and its singular value decomposition, the selection of principal components related to various components of the series (from slowly changing and periodic to noise), and, finally, line restoration.
The scope of the algorithm is The problems of both meteorology and geophysics, and economics and medicine. The purpose of this work is to find out the dependence of the efficiency of the algorithm on the choice of time series used in its work.

14. 2011

Using the Granger Test in Time Series Forecasting
When predicting a series, it can be useful to determine whether a given series is "dependent" on some other series. The Granger test, based on statistical tests, helps to identify such a relationship (in this case, the method does not guarantee an accurate result - when comparing two rows that depend on another row, an error is possible). The method is used in forecasting economic and natural phenomena (for example, earthquakes).
The purpose of the work is to propose an algorithm that makes the best use of this method; investigate the effectiveness of the method depending on the predicted series.

+* '''Title:''' Simulating the Dynamics of Physical Systems with Physics-Informed Neural Networks
+* '''Problem description:''' The problem of choosing the optimal model for predicting the dynamics of a physical system is being solved. Under the dynamics of the system is understood the change in time of the parameters of the system. Neural networks do not have a priori knowledge about the system being modeled, which does not allow obtaining optimal parameters that take into account physical laws. The Lagrangian neural network takes into account the law of conservation of energy when modeling dynamics. In this paper, a Noetherian Agrangian neural network is proposed that takes into account the laws of conservation of momentum and angular momentum in addition to the law of conservation of energy. It is shown that for this problem the Noetherian Lagrangian neural network is optimal among the fully connected neural network model, the neural network with long-term short-term memory and the Lagrangian neural network. The simulation comparison was carried out on artificially generated data for the double pendulum system, which is the simplest chaotic system. The results of the experiments confirm the hypothesis that the introduction of a priori knowledge about the physics of the system improves the quality of the model.

For the process of multiple training, prediction and updating of the sample, we build a mathematical model and study the properties of this process based on the constructed model. Let f(x) be a feature distribution density function, G be an algorithm for training the model, generating predictions on the test set and mixing predictions into the training set, as a result of which the feature distribution changes. Let the space of non-negative smooth functions F(x) be given, whose integral on R^n is equal to one. f_{t+1}(x) = G(f_{t})(x), where G(f) is the evolution operator on the space of these functions F and the initial function f_0(x) is known. In general, G can be an arbitrary operator, not necessarily smooth and/or continuous. Question 0. Find conditions on the operator G under which the image of G lies in the same class of distribution density functions F. In particular, should G be bounded, the operator norm ||G|| <= 1, so that the image of G(f) \in F is also a distribution density function for any f from F? Does there exist a unit in the space F with respect to the operator G, and what will be the identity function f in such F? Question 1.

The problem is to find formulaic and quantitative relationships between the parameters under which the lockdown can lead to an increase in the epidemic.

+*# FBNet: choosing a model architecture based on target characteristics
+* '''Base algorithm:''' FBNet and random search of model substructure
+* '''Solution:''' The proposed method is to use a differentiable neural network architecture search algorithm (FBNet) with parameter complexity control using a hypernet. A hypernetwork is a model that generates the structure of the model depending on the input parameters. It is proposed to use the normalized running time of basic operations on target computing resources as hypernet parameters. Thus, the resulting model will allow adapting the architecture of the model for an arbitrary device. * '''Novelty:''' The proposed method allows you to control the complexity of the model, in the process of searching for an architecture without additional heuristics.

+* '''Problem description:''' Wildfire risk prediction based on climate variables (water/air temperature, atmospheric pressure) since 1991. Forecasting is carried out (a) in the short-term range (2-5 years; stationary time series) and (b) in the long-term range (up to 50 years; non-stationary time series). A feature of forecasting in the long range is the (probable) significant change in the behavior of climate variables (CMIP5 scenarios). The key features of problem (1) are the need for a sufficiently accurate prediction of extreme risk values (maximum values of the time series), while the algorithm can make a significant number of errors in the region of small values of the series. (2) the spatial data structure of the series.

+* '''Base algorithm:''' (1) method from article 1, (2). ST-LSTM
+* '''Solution:''' is proposed to solve the problem in two steps. At the first step, Algorithm 1 (with the addition of a spatial component) restores (averaged over a certain range) the behavior of the time series. Next, the discrepancy between the values of the series and the model is analyzed. Based on this, the noise distribution is restored and a probabilistic model is built to achieve a certain level of risk in a given territory in the required time range.
+* '''Novelty:''' (geo)-spatial time series prediction is an open area with great potential for theoretical and practical work. In particular, fire risk assessment is necessary for (1) predicting the probability of accidents (electric power industry, gas transport complex); (2) prioritization of fire prevention measures by region; (3) assessing the financial risks of companies operating in the region.

Forecasting is carried out (a) in the short-term range (2-5 years; stationary time series) and (b) in the long-term range (up to 50 years; non-stationary time series). A feature of forecasting in the long range is the (probable) significant change in the behavior of climate variables (CMIP5 scenarios). Key features of The problem (1) rare events, the case of hail in Russia over the past 30 years was less than 700 throughout the country (2) the spatial structure of the data series.

+* '''Base algorithm:''' there are several different options on the Internet, for example, the article B.Tseytlin Actually forecasting COVID-19 LINK, the current program does not give good convergence, because it always uses a fixed number of points for prediction
+* '''Novelty:''' a new LLGMM method of moments that increases the accuracy of prediction& The basic idea of the method of moments is to use in moment conditions (moment functions or simply moments) instead of mathematical expectations, sample means, which, according to the law of large numbers under sufficiently weak conditions, should converges asymptotically to the mathematical expectations. Since the number of conditions for moments in the general case is greater than the number of estimated parameters, this system of conditions does not have a unique solution. The generalized method of moments suggests a situation where it is possible to obtain more conditions for moments than estimated parameters. The method constructs moment conditions (moment functions), also called orthogonality conditions, in a more general form as some function of model parameters and data. The parameters are estimated by minimizing a certain positive quadratic form from the sample means for the moments (moment functions). The quadratic form is in an iterative process with the required accuracy. If the model contains more than one parameter (this is our case) to be identified, then the second and higher moments are used to construct moment conditions. LLGMM defines time-dependent parameters by using a limited number of "points" in a data time series to form moment conditions, rather than the entire series. So the method is late. In addition, the number of time series elements used varies for each estimate over time. Thus, the method is local and adaptive.

+* '''Title:''' Impact of the lockdown on the dynamics of the epidemic
+* '''Problem description:''' The introduction of a lockdown is considered an effective measure to combat the epidemic. However, contrary to intuition, it turned out that under certain conditions, a lockdown can lead to an increase in the epidemic. This effect is absent for classical models “on average”, but was revealed when modeling the spread of the epidemic, taking into account the contact graph. The problem is to find formulaic and quantitative relationships between the parameters under which the lockdown can lead to an increase in the epidemic.
+* '''Data:''' Real data on the spread of the epidemic on contact graphs, especially considering the need for scenario analysis, is not available. The problem involves working with model and synthetic data: there are ready-made data, and it is also assumed that new ones can be generated in the process of solving the problem.

+* '''Introduction:''' [http://www.machinelearning.ru/wiki/images/f/fa/M1p_ppis.pdf See full description here]. Proteins are involved in several biological reactions by means of interactions with other proteins or with other molecules such as nucleic acids, carbohydrates, and ligands. Among these interaction types, protein–protein interactions (PPIs) are considered to be one of the key factors as they are involved in most of the cellular processes [1]. The binding of two proteins can be viewed as a reversible and rapid process in an equilibrium that is governed by the law of mass action. Binding affinity is the strength of the interaction between two (or more than two) molecules that bind reversibly (interact). It is translated into physico-chemical terms in the dissociation constant Kd, the latter being the concentration of free protein at which half of all binding sites of the second protein type are occupied [2].
+* '''Objectives:'''  Three main objectives of this work can be formulated as follows: 1. Refine PDBbind [12] data and a standard binding affinity dataset [3], and compile a novel benchmark of PPIs with known binding affinity values. 2. Employ graph-learning toolset to predict binding affinities of PPIs from the new dataset. 3. Benchmark the resulting method against existing state-of-the-art approaches
+* '''Data & Metrics:''' In this work, we will operate on experimentally-observed three-dimensional structures of protein-protein complexes annotated with the binding affinity values. Two main sources of data are the following:
+* PDBbind dataset [12] that includes around 2k PPIs
+* Standard dataset introduced in [3] that includes 144 PPIs As main regression metrics, we suggest to consider Mean Squared Error (MSE), Mean Absolute Error (MAE) and Pearson correlation.
+* '''Novelty:''' To the best of our knowledge, geometric deep learning methods have never been applied to the protein-protein binding affinity prediction problem so far.

+* '''Title:''' Continuous time when building a BCI neural interface
+* '''Problem description:''' In Signal Decoding The problems, data is represented as multivariate time series. When solving problems, a discrete representation is used time. However, recent work on neural ordinary differential equations illustrates the ability to work with the hidden state of recurrent neural networks, as with solutions to differential equations. This allows us to consider time series as continuous in time.

+* '''Literature:''' Vorontsov K. V. Probabilistic thematic modeling: review of models and additive regularization [http://www.machinelearning.ru/wiki/images/d/d5/Voron17survey-artm.pdf PDF]
+* '''Base algorithm:'''
+*# Hierarchical topic models
+*# Topic models with one-pass document vectorization
+* '''Solution:''' To solve the search problem, a multimodal thematic model was built. 100 languages were used as modalities, as well as scientific headings, which included articles from the training data. A series of experiments was carried out to improve search quality metrics, including: selection of the optimal tokenization method, addition of regularizers, selection of thematic vector comparison functions, ranking functions, etc.
+* '''Novelty:''' Most systems for finding documents in large collections are based on vectorization of the documents in the collection and the search document in one way or another. The latest ways to vectorize documents are usually limited to one language. In this case, the problem arises of creating a uniform system for obtaining vector embeddings of a multilingual collection of documents. The proposed approach makes it possible to train a topic model that encodes information about the distribution of words in a text, regardless of their language affiliation. Also, the solution is subject to restrictions on the size of the model and training time, due to the possibility of practical use of the described model.

Therefore, the existing operations of convolutions on graphs are greatly simplified or do not generalize to different topologies. In this paper, we propose to consider a new method for constructing a convolution operation on three-dimensional graphs, for which it is possible to uniquely choose local coordinate systems associated with each node.

-|[[Участник:Dmitriy Dmitrichenko|Дмитриченко Дмитрий]]
+* '''Problem description:''' In recommender systems, the effect of artificially inadvertently limiting the user's choice due to the adaptation of the model to his preferences (echo chamber / filter bubble) is known. The effect is a special case of hidden feedback loops. (see - Analysis H.F.L.). It is expressed in the fact that by recommending the same objects of interest to the user, the algorithm maximizes the quality of its work. The problem is a) lack of variety b) saturation / volatility of the user's interests.

+* '''Problem description:'''It is clear that the algorithm does not know the interests of the user and the user is not always honest in his choice. Under what conditions, what properties of the learning algorithm and dishonesty (deviation of the user's choice from his interests) will the indicated effect be observed? Clarification. The recommendation algorithm gives the user a_t objects to choose from. The user selects one of them c_t from Bernoulli from the model of interest mu(a_t) . Based on the user's choice, the algorithm changes its internal state w_t and gives the next set of objects to the user. On an infinite horizon, you need to maximize the total reward sum c_t. Find the conditions for the existence of an unlimited growth of user interest in the proposed objects in a recommender system with the Thomson Sampling (TS) MAB algorithm under conditions of noisy user choice c_t. Without noise, it is known that there is always unlimited growth (in the model) [1].

-===Задача 74===
-* '''Название:''' Existence conditions for hidden feedback loops in recommender systems
-* '''Описание проблемы:''' В рекомендательных системах известен эффект искусственного непреднамеренного ограничения выбора пользователя вследствие адаптации модели к его предпочтениям (echo chamber/filter bubble). Эффект является частным случаем петель скрытой обратной связи (hidden feedback loop). (см. - Analysis H.F.L.). Выражается в том, что путем рекомендации одних и тех же интересных пользователю объектов, алгоритм максимизирует качество своей работы. Проблема в а) недостаточном разнообразии б) насыщении / изменчивости интересов пользователя.
-* '''Задача: '''Понятно, что алгоритм не знает интересов пользователя и пользователь не всегда честен в выборе. При каких условиях, каких свойствах алгоритма обучения и нечестности (отклонении выбора пользователя от его интересов) будет наблюдаться указанный эффект? Уточнение. Рекомендательный алгоритм выдает пользователю объекты a_t на выбор. Пользователь выбирает один из них c_t из Бернулли от модели интереса mu(a_t) . На основе выбора пользователя алгоритм изменяет свое внутреннее состояние w_t и выдает следующий набор объектов пользователю. На бесконечном горизонте нужно максимизировать суммарное вознаграждение sum c_t. Найти условия существования неограниченного роста интереса пользователя к предлагаемым объектам в рекомендательной системе с алгоритмом Thomson Sampling (TS) MAB в условиях зашумленности выбора пользователя c_t. Без шума известно, что всегда неограниченный рост (в модели) [1].

Затем проверить их выполнение в имитационной модели. Для проверки выполняется серия экспериментов с исследованием диапазонов параметров и оценкой ошибки (variance) моделирования. Результаты сопоставляются с построенной ранее математической моделью эффекта. Есть реализация системы проведения эксперимента, которую можно доработать для данной задачи.
+* '''Solution:''' It is necessary to derive conditions for the existence of positive feedback for the Thomson Sampling Multi-armed Bandit algorithm based on the known theoretical properties of this algorithm. Then check their performance in the simulation model. For verification, a series of experiments is performed with the study of parameter ranges and the estimation of the error (variance) of the simulation. The results are compared with the previously constructed mathematical model of the effect. There is an implementation of the experiment system that can be improved for this The problem.

There is his model for the limited case of the absence of noise in the user's actions, which is not implemented in practice. Under the proposed conditions, The problem has not previously been posed and not solved for recommender systems. For the regression problem, the solution is known.

-* '''Задача:''' Исследуется широкий класс периодических движений человека или животного. Требуется найти начало и конец движения. Требуется понять, когда заканчивается один тип движения и начинается другой. Для этого решается задача сегментации временных рядов. Строится фазовая траектория одного движения и отыскивается его фактическая размерность. Цель работы в том, что надо описать способ нахождения минимальной размерности фазового пространства. По повторению фазовой сегментировать периодические действия человека. Надо также предложить метод извлечения нулевой фазы в данном пространстве для конкретного действия.

+* '''Title:''' Determining the phase and disorder of human movement by signals from wearable devices
-* '''Задача:''' Задачи оптимизации с вероятностными ограничениями часто встречаются в инженерной практике. Например, задача минимизации генерации энергии в энергетических сетях, со (случайным образом флуктуирующими) возобновляемыми источниками энергии. При этом необходимо выполнение ограничений безопасности: напряжения у генераторов и потребителей, а также токи на линиях должны быть меньше определенных порогов. Вместе с тем, даже в самых простых ситуациях задача не может быть разрешена точно. Самый известный подход, это методы chance constrained optimization, которые часто дают неплохое приближение. Альтернативный подход – семплирование режимов работы сети и решения задачи на наборе данных задачи классификации: отделение плохих режимов от хороших с заданной ошибкой второго рода. Вместе с тем, для достаточно точного решения, требуются очень большой объем данных, что часто делает задачу численно не эффективной. Мы предлагаем использовать “семплирование по важности” (importance sampling) для уменьшения числа сценариев. Семплирование по важности состоит из подмены выборки из номинального решения, которое часто не несет информации так как все плохие события очень редки, на синтетическое распределение, которое семплирует выборку в окрестности плохих событий.
+* '''Problem description:''' A wide class of periodic movements of a person or an animal is investigated. It is required to find the beginning and end of the movement. It is required to understand when one type of movement ends and another begins. For this, The problem of segmentation of time series is solved. The phase trajectory of one movement is constructed and its actual dimension is found. The purpose of the work is to describe a method for finding the minimum dimension of the phase space. By repetition of the phase, segment the periodic actions of a person. It is also necessary to propose a method for extracting the zero phase in a given space for a specific action. Bonus: find the discord in the phase trajectory and indicate the change in the type of movement. Bonus 2: do this for different phone positions by proposing invariant transformation models.

-* '''Задача:''' Методы машинного обучения в настоящий момент широко применяются в физике, в частности при решении задач турбулентности или анализа устойчивости физических сетей. Вместе с тем ключевым вопросом является какие режимы выбирать для обучения моделей. Частый выбор – последовательности точек, равномерно покрывающие допустимое множество. Однако, часто такие последовательности мало информативны, особенно в случае, если аналитические методы дают область, где система гарантированно устойчива. В задаче предлагается несколько методов семплирования: позволяющих учесть эту информацию. Нашей целью является их сравнить и найти тот, который требует минимального размера выборки (эмпирическое сравнение).
+* '''Problem description:''' Optimization problems with probabilistic constraints are often encountered in engineering practice. For example, The problem of minimizing energy generation in energy networks, with (randomly fluctuating) renewable energy sources. In this case, it is necessary to comply with safety restrictions: voltages at generators and consumers, as well as currents on the lines, must be less than certain thresholds. However, even in the simplest situations, The problem cannot be resolved exactly. The best-known approach is the chance constrained optimization methods, which often give a good approximation. An alternative approach is sampling the network operation modes and solving the problem on the data set of the classification * '''Problem description:''' separating bad modes from good ones with a given error of the second kind. At the same time, for a sufficiently accurate solution, a very large amount of data is required, which often makes the problem numerically inefficient. We suggest using “importance sampling” to reduce the number of scenarios. Importance sampling consists of substituting a sample from a nominal solution, which often carries no information since all bad events are very rare, with a synthetic distribution that samples the sample in a neighborhood of bad events.

-* '''Задача:'''  Задача выбора оптимальной архитектуры нейросети ставится как задача семплирования вектора структурных параметров. Критерий оптимальности определяется в терминах точности, сложности и устойчивости модели. Сама процедура семплирования состоит из двух шагов: порождение новой структуры и отклонение этой структуры, если она не удовлетворяет критерию оптимальности. Предлагается исследовать различные способы семплирования.

+* '''Problem description:''' Machine learning methods are currently widely used in physics, in particular, in solving turbulence problems or analyzing the stability of physical networks. At the same time, the key issue is which modes to choose for training models. A frequent choice is a sequence of points that uniformly covers the admissible set. However, often such sequences are not very informative, especially if analytical methods give a region where the system is guaranteed to be stable. The problem proposes several methods of sampling: allowing to take into account this information. Our goal is to compare them and find the one that requires the smallest sample size (empirical comparison).

-* '''Решение:''' Сейчас уже выполнен ряд экспериментов, где семплирования производится генетическим алгоритмом. Получены приемлемые результаты. Предлагается их проанализировать и улучшить. А именно, выделить два модуля: порождение и отклонение и сравнить несколько видов семплирования. Базовый — Importance sampling, желанный — Metropolis-Hastings (или даже Metropolis-Langevin) sampling. Так как генетический алгоритм рассматривается нами как процесс со скачками, то предлагается учесть это при проектировании процедуры семплирования. Бонус MH в том, что он имеет байесовскую интерпретацию. Первый уровень байесовского вывода применительно к MH описан в работе [Informatica]. Требуется либо переписать его в терминах распределения структурных параметров, либо вообще расписать оба уровня, вынеся структурные параметры во второй уровень (кстати, примерно то же будет в задаче Адуенко).
+* '''Solution:''' A number of experiments have already been performed, where sampling is performed by a genetic algorithm. Acceptable results have been obtained. It is proposed to analyze and improve them. Namely, to distinguish two modules: generation and deviation and compare several types of sampling. Basic - Importance sampling, desirable - Metropolis-Hastings (or even Metropolis-Langevin) sampling. Since the genetic algorithm is considered by us as a process with jumps, it is proposed to take this into account when designing the sampling procedure. The bonus of MH is that it has a Bayesian interpretation. The first level of Bayesian inference as applied to MH is described in [Informatica]. It is required either to rewrite it in terms of the distribution of structural parameters, or to describe both levels in general, moving the structural parameters to the second level (by the way, approximately the same will be in the Aduenko problem).

Одна из главных целей нейросетей -хорошо выполнять задачи, которые в настоящее время решаются исключительно человеком, то есть природными нейронными сетями людей. Искусственные нейросети по-прежнему работают совсем не так, как естественные нейронные сети. Одно из основных различий заключается в том, что естественные нейронные сети со временем развиваются, меняя силу связей и свою архитектуру. Искусственные нейронные сети могут регулировать силу соединений с помощью весов, но не могут изменять свою архитектуру. Поэтому задача выбора оптимальных структур нейросетей под конкретные задачи представляется важным шагом в развитии способностей нейросетевых моделей.

One of the main goals of neural networks is to perform well The problems that are currently solved exclusively by humans, that is, natural human neural networks. Artificial neural networks still work very differently from natural neural networks. One of the main differences is that natural neural networks evolve over time, changing the strength of connections and their architecture. Artificial neural networks can adjust the strength of connections using weights, but cannot change their architecture. Therefore, The problem of choosing the optimal structures of neural networks for specific The problems seems to be an important step in the development of the capabilities of neural network models.

Особенность задачи в том, что при прогнозе требуется моделировать не только исходный сигнал, снимаемый с коры головного мозга, но и целевой, снимаемый с конечностей.

-* '''Задача:''' Рассматривается задача оптимизации параметров модели глубокого обучения. Рассматривается случай, когда при оптимизации доступны ответы более сложной модели (модели-учителя).  Классическим подходом к решению такой задачи является обучение с учетом ответов сложной модели (дистилляция знаний). Назначение гиперпараметров производится эмпирически на основе результатов работы модели на отложенной выборке. В данной работе предлагается рассмотреть модификацию подхода к дистилляции знаний, в котором гиперпараметрами выступает коэффициент значимости дистиллирующего слагаемого, а также его градиенты. Обе эти группы параметров позволяют скорректировать оптимизацию параметров модели. Для оптимизации гиперпараметров предлагается рассматривать задачу оптимизации как двухуровневую задачу оптимизации, где на первом уровне оптимизации решается задача оптимизации параметров модели, а на втором --- приближенно решается задача оптимизации гиперпараметров по значению функции потерь на отложенной выборке.
+* '''Problem description:''' The problem of optimizing the parameters of a deep learning model is considered. The case is considered when the responses of a more complex model (teacher model) are available during optimization. The classical approach to solving such a problem is learning based on the responses of a complex model (knowledge distillation). Assignment of hyperparameters is made empirically based on the results of the model on delayed sampling. In this paper, we propose to consider a modification of the approach to knowledge distillation, in which the coefficient of significance of the distilling term, as well as its gradients, act as hyperparameters. Both of these groups of parameters allow you to adjust the optimization of the model parameters. To optimize hyperparameters, it is proposed to consider the optimization problem as a two-level optimization problem, where at the first level of optimization The problem of optimizing the model parameters is solved, and at the second level The problem of optimizing hyperparameters is approximately solved by the value of the loss function on the delayed sample.

-* '''Задача:''' Работа посвящена тестированию методов выбора признаков. Предполагается, что исследуемая выборка содержит значительное число мультиколлинеарных признаков. Мультиколлинеарность — это сильная корреляционная связь между отбираемыми для анализа признаками, совместно воздействующими на целевой вектор, которая затрудняет оценивание регрессионных параметров и выявление зависимости между признаками и целевым вектором.  Имеется набор временных рядов, содержащих показания различных датчиков, отражающих состояние устройства. Показания датчиков коррелируют между собой. Необходимо выбрать оптимальный набор признаков для решения задачи прогнозирования.
+* '''Problem description:''' The work is devoted to testing methods for feature selection. It is assumed that the sample under study contains a significant number of multicollinear features. Multicollinearity is a strong correlation between the features selected for analysis that jointly affect the target vector, which makes it difficult to estimate regression parameters and identify the relationship between features and the target vector. There is a set of time series containing the readings of various sensors that reflect the state of the device. The readings of the sensors correlate with each other. It is necessary to choose the optimal set of features for solving the forecasting problem.

В работах по поиску структур нейросетей также пока нет внятной теории и списка априорных предположений.

-*'''Название:''' Поиск границ радужки методом круговых проекций
+*'''Name:''' Search for the boundaries of the iris by the method of circular projections
-*'''Задача:''' Дано монохромное растровое изображение глаза, [[Media:Matveev2021project.pdf|см. примеры]].  Также известно приблизительное положение центра зрачка. Слово «приблизительное» означает то, вычисленный центр зрачка отстоит от истинного не более чем на половину его истинного радиуса. Необходимо определить приблизительные положения окружностей, аппроксимирующих зрачок и радужку. Алгоритм должен быть очень быстрым.
+*'''Problem:''' Given a monochrome bitmap of the eye, [http://www.machinelearning.ru/wiki/images/1/16/Matveev2021project.pdf examples]. The approximate position of the center of the pupil is also known. The word "approximate" means that the calculated center of the pupil is no more than half of its true radius from the true one. It is necessary to determine the approximate positions of the circles approximating the pupil and iris. The algorithm must be very fast.
-*'''Данные:''' около 200 тыс. изображений глаз. Для каждого размечено положение истинных окружностей — в целях обучения и проверки создаваемого метода.
+*'''Data:''' About 200 thousand eye images. For each, the position of the true circles is marked - for the purpose of training and testing the method being created.
-*'''Базовой алгоритм:''' Для ускорения работы с изображением предлагается агрегирование данных при помощи круговых проекций яркости. Круговая проекция — функция, зависящая от радиуса, значение которой P(r) равно интегралу направленного градиента яркости изображения по окружности радиуса r (или по дуге окружности). Пример для одной дуги (правой четверти) и для четырёх дуг. Построив сколько-то круговых проекций, исходя из них, можно попытаться определить положение внутренней и внешней границ радужки (кольца) при помощи эвристик и/или нейросети. Интересно оценить возможности нейросети в данной задаче.
+*'''Basic algorithm:''' To speed up work with the image, it is proposed to aggregate data using circular projections of brightness. Circular projection is a function that depends on the radius, the value of which P(r) is equal to the integral of the directed image brightness gradient over a circle of radius r (or along an arc of a circle). Example for one arc (right quadrant) and for four arcs. Having built some circular projections, based on them, you can try to determine the position of the inner and outer borders of the iris (ring) using heuristics and / or a neural network. It is interesting to evaluate the capabilities of the neural network in this The problem.

-* '''Базовой алгоритм''': В задаче классификации мы использовали алгоритм, похожий на линейный SVM, связь которого с оценкой энергии, выходящей за рамки задачи классификации, описана в статье https://hal.inria.fr/hal-01591154/. Для MSE в качестве функции потерь регрессии уже есть сформулированная двойственная задача, с реализации которой можно начать.
+* '''Base algorithm:'''  In the classification The problem, we used an algorithm similar to linear SVM, whose relationship with the energy estimate, which is outside the scope of the classification The problem, is described in the article https://hal.inria.fr/hal-01591154/. For MSE, there is already a formulated dual The problem as a regression loss function, with the implementation of which we can start.
-* '''Решение''': Первым этапом будет решение задачи с MSE в функции потерь с использованием удобного для вас солвера. Основной трудностью может стать большая размерность данных, но они разрежены. Далее можно будет менять формулировку задачи.
+* '''Solution:''' The first step is to solve the problem with the MSE in the loss function using a solver that is convenient for you. The main difficulty may be the large dimensionality of the data, but they are sparse. Further it will be possible to change the wording of the problem.
-* '''Новизна''': Многие модели, используемые для предсказания взаимодействий белков с лигандами, "переобучены" под какую-либо задачу. Например, модели, хорошо предсказывающие энергии связывания, могут плохо выбирать связывающуюся с белком молекулу из множества несвязывающихся, а модели, хорошо определяющие правильную геометрию комплекса, могут плохо предсказывать энергии. В данной задаче предлагается рассмотреть новый подход борьбы с таким переобучением, поскольку сочетание функций потерь классификации и регрессии видится нам очень естественной регуляризацией.
+* '''Novelty:''' Many models used to predict the interactions of proteins with ligands are "retrained" for some The problem. For example, models that are good at predicting binding energies may be poor at selecting a protein-binding molecule from a variety of non-binding ones, and models that are good at determining the correct geometry of the complex may be poor at predicting energies. In this problem, we propose to consider a new approach to combat such overfitting, since the combination of classification and regression loss functions seems to us to be a very natural regularization.

-* '''Задача:''' Задан набор символов. Каждый символ представлен одним файлом - изображением. Размер изображений в пикселях может отличаться.  Известно, что все изображения принадлежат одному классу, например, лица, буквы, цветы или машины. (Более сложный вариант - одному классу, который мы исследуем и шумовым классам.) Известно, что каждое изображение может быть и помощью выравнивающей трансформации совмещено с другим с точностью до шума, либо до некоторого усредненного изображения. (Это изображение может как присутствовать, так и отсутствовать в выборке). Эта выравнивающая трансформация задается в базовом случае нейросетью, а в предлагаемом - параметрическим преобразованием из некоторого заданного класса (первое - частный случай второго). Выравненное изображение сравнивается с исходным с помощью функции расстояния.  Если расстояние между двумя изображениями статистически значимо, делается вывод о принадлежности изображений одному классу.  Требуется 1) предложить адекватную модель выравнивающей трансформации, которая берет в расчет предположения о характере изображения (например, только вращение и пропорциональное масштабирование), 2) предложить функцию расстояния, 3) преложить способ нахождения усредненного изображения.
+* '''Problem description:''' Character set specified. Each symbol is represented by one file - an image. Image pixel size may vary. All images are known to belong to the same class, such as faces, letters, flowers, or cars. (A more complicated option is to one class, which we are studying and noise classes.) It is known that each image can be combined with another with the help of an equalizing transformation up to noise, or up to some average image. (This image may or may not be present in the sample). This leveling transformation is specified in the base case by a neural network, and in the proposed case - by a parametric transformation from some given class (the first is a special case of the second). The aligned image is compared with the original one using the distance function. If the distance between two images is statistically significant, it is concluded that the images belong to the same class. It is required to 1) propose an adequate model of the alignment transformation that takes into account the assumptions about the nature of the image (for example, only rotation and proportional scaling), 2) propose a distance function, 3) propose a method for finding the average image.

Построив несколько проекций (две, четыре), исходя из них, можно попытаться определить положение зрачка (компактной тёмной области) при помощи эвристик и/или нейросети. Интересно оценить возможности нейросети в данной задаче.
+'''Basic algorithm:''' To speed up work with the image, it is proposed to aggregate data using brightness projections. Image brightness is a function of two discrete arguments. Its projection on the horizontal axis is equal to. Similarly, projections are constructed on axes with an inclination. Having built several projections (two, four), based on them, you can try to determine the position of the pupil (compact dark area) using heuristics and / or a neural network. It is interesting to evaluate the capabilities of the neural network in this The problem.

+*'''Name:''' Searching for a century in an image as a parabolic contour using the projection method.
+*'''Problem:''' Given a monochrome bitmap of the eye, [[Media:Matveev2021project.pdf|examples]]. It is necessary to find the contour of the upper eyelid as a parabola, that is, to determine the parameters.
+*'''Data:''' About 200 thousand eye images. For some (about 2500), a human expert marked the position of a parabola that approximates the eyelid.
+*'''Basic algorithm:''' The first step is pre-processing the image with a vertical gradient filter with further binarization, below is a typical result. There are various options for the next step. For example, if the coordinates of the pupil are known, you can set the region of interest (from above) and in it, using the selected points, construct a parabola by approximation using the least squares method. An example result is given below. More subtle methods are possible, such as finding a parabola using the Hough transform (see Wikipedia). Another way is to use projective methods (Radon transform). The main idea: after specifying the coefficient , apply a coordinate transformation to the image, as a result of which all parabolas of the form formula turn into lines of the form , then, given the coefficient , apply the coordinate transformation where , after which the oblique lines of the formula form become horizontal, which are easy to determine, for example, by horizontal projection (by summing the values in the rows of the matrix of the resulting image. If the coefficients are guessed correctly, the perabola representing the eyelid will give a clear maximum in the projection. By going through the formula (having a physical meaning), you can find those that give the maximum projection value, and consider that the desired parabola - eyelid.

+* '''Title:''' Construction of a method for dynamic alignment of multidimensional time series, resistant to local signal fluctuations.
+* '''Problem description:''' In the process of working with multidimensional time series, the situation of the close proximity of sensors corresponding to different measurement channels is common. As a result, small signal shifts in space can lead to signal peak fixation by neighboring sensors, which leads to significant differences in measurements in terms of L2 distance.<br />Thus, small signal shifts lead to significant fluctuations in the readings of the sensors. The problem of constructing a distance function between points of time series that is resistant to noise generated by small spatial signal shifts is considered. It is necessary to consider the problem in the approximation of the presence of a map of the location of the sensors.

Then the object at the lower level of abstraction is the original signal. At the second level - a signal from the hidden layer of the model (built on the objects of the lower level), the dimension of which is much less, and the upper layer - a signal from the hidden layer of the model (built on the objects of the middle level).<br />In this case, DTW is calculated separately between the lower , between the middle and between the upper levels, but the formation of objects for calculating the distance is carried out taking into account the alignment path between the objects of the previous level.<br />This method is considered as a way to increase the interpretability of the alignment procedure and the accuracy of the action classification in connection with the transition to higher-level patterns. In addition, a significant increase in speed is expected.

+* '''Solution:''' As a translation model, it is proposed to consider a combination of two auto-encoders, each of which is responsible for presenting sentences in one of the languages. The models are optimized in such a way that the latent spaces of autoencoders for different languages match. As an initial representation of sentences, it is proposed to consider their graph description obtained using multilingual ontologies.

-* '''Задача''': Рассматривается задача построения модели перевода текста без использования параллельных текстов, т.е. пар одинаковых предложений на разных языках. Данная задача возникает при построении моделей перевода для низкоресурсных языков (т.е. языков, для которых  данных в открытом доступе немного).
+* '''Problem:''' It is required to check the feasibility of the hypothesis about the simplicity of sampling for the generated features. Features are the optimal parameters of approximating models. Moreover, the entire sample is not simple and requires a mixture of models to approximate it. Explore the information content of the generated features - the parameters of the approximating models trained on the segments of the original time series. According to the measurements of the accelerometer and gyroscope, it is required to determine the type of activity of the worker. It is assumed that the time series of measurements contain elementary movements that form clusters in the space of time series descriptions. The characteristic duration of the movement is seconds. Time series are labeled with activity type labels: work, leisure. The typical duration of activity is minutes. It is required to restore the type of activity according to the description of the time series and cluster.

-* '''Задача''': Требуется проверить выполнимость гипотезы о простоте выборки для порожденных признаков. Признаки - оптимальные параметры аппроксимирующих моделей. При этом вся выборка не является простой и требует смеси моделей для ее аппроксимации. Исследовать информативность порожденных признаков - параметров аппроксимирующих моделей, обученных на сегментах исходного временного ряда. По измерениям акселерометра и гироскопа требуется определить вид деятельности рабочего. Предполагается, что временные ряды измерений содержат элементарные движения, которые образуют кластеры в пространстве описаний временных рядов. Характерная продолжительность движения – секунды.  Временные ряды размечены метками вида деятельности: работа, отдых.  Характерная продолжительность деятельности – минуты. Требуется по описанию временного ряда и кластера восстановить вид деятельности.

+*'''Problem''': In this paper, we consider The problem of constructing a universal approximator --- a multimodel, which consists of a given finite set of local models. Each local model approximates a connected region in feature space. It is assumed that the set of local models cover the entire space of objects. A convex combination of local models is considered as an aggregating function. As the coefficients of the convex combination, we consider a function depending on the object --- the gate function.

-* '''Название''': Предсказание качества моделей белков с помощью сферических сверток на трехмерных графах.
-* '''Задача''': Целью данной работы является создание и исследование новой операции свертки на трехмерных графах в рамках решения задачи оценивания качества трехмерных моделей белков (задача регрессии на узлах графа).

-* '''Решение''': Наличие в белках пептидной цепи позволяет однозначно вводить локальные системы координат для всех узлов графа, что дает возможность создавать и применять сферические фильтры независимо от топологии графа.
-* '''Новизна''': В общем случае графы являются нерегулярными структурами, а во многих задачах обучения на графах объекты выборки не имеют единой топологии. Поэтому существующие операции сверток на графах очень сильно упрощены, либо не обобщаются на разные топологии. В данной работе предлагается рассмотреть новый способ построения операции свертки на трехмерных графах, для которых возможно однозначно выбрать локальные системы координат, привязанные к каждому узлу.

+* '''Title:''' Finding the pupil in the eye image using the brightness projection method.
+* '''Problem:''' Given a monochrome bitmap of the eye, see examples (https://cloud.mail.ru/public/eaou/4JSamfmrh).
+It is necessary to determine the approximate coordinates of the center of the pupil. The word "approximate" means that the calculated pupil center must lie inside a circle centered at the pupil's true center and half the true radius. The algorithm must be very fast.
+* '''Data:''' About 200 thousand eye images. For each, the position of the true circle is marked - for the purpose of training and testing the method being created.
+* '''Base algorithm:'''  To speed up work with the image, it is proposed to aggregate data using brightness projections. Image brightness is a function of two discrete arguments I(x, y). Its projection onto the horizontal axis is P(x)=\sum \limits_y I(x,y). Similarly, projections are constructed on axes with an inclination. Having built several projections (two, four), based on them, you can try to determine the position of the pupil (compact dark area) using heuristics and / or a neural network. It is interesting to evaluate the capabilities of the neural network in this The problem.

+* '''Base algorithm:'''  To speed up work with the image, it is proposed to aggregate data using circular projections of brightness. Circular projection is a function that depends on the radius, the value of which P(r) is equal to the integral of the directed image brightness gradient over a circle of radius r (or along an arc of a circle). Example for one arc (right quadrant) and for four arcs. Having built some circular projections, based on them, you can try to determine the position of the inner and outer borders of the iris (ring) using heuristics and / or a neural network. It is interesting to evaluate the capabilities of the neural network in this The problem.

-* '''Базовой алгоритм''': В задаче классификации мы использовали алгоритм, похожий на линейный SVM, связь которого с оценкой энергии, выходящей за рамки задачи классификации, описана в статье https://hal.inria.fr/hal-01591154/. Для MSE в качестве функции потерь регрессии уже есть сформулированная двойственная задача, с реализации которой можно начать.
-* '''Решение''': Первым этапом будет решение задачи с MSE в функции потерь с использованием удобного для вас солвера. Основной трудностью может стать большая размерность данных, но они разрежены. Далее можно будет менять формулировку задачи.
-* '''Новизна''': Многие модели, используемые для предсказания взаимодействий белков с лигандами, "переобучены" под какую-либо задачу. Например, модели, хорошо предсказывающие энергии связывания, могут плохо выбирать связывающуюся с белком молекулу из множества несвязывающихся, а модели, хорошо определяющие правильную геометрию комплекса, могут плохо предсказывать энергии. В данной задаче предлагается рассмотреть новый подход борьбы с таким переобучением, поскольку сочетание функций потерь классификации и регрессии видится нам очень естественной регуляризацией.

-===Задача 54 ===
-* '''Название''': Поиск зрачка на изображении глаза методом проекций яркости.
-* '''Задача''': Дано монохромное растровое изображение глаза, см. примеры (https://cloud.mail.ru/public/eaou/4JSamfmrh).
-Необходимо определить приблизительные координаты центра зрачка. Слово «приблизительные» означает то, что вычисленный центр зрачка должен лежать внутри окружности с центром в истинном центре зрачка и половинного истинного радиуса. Алгоритм должен быть очень быстрым.
-* '''Данные''': около 200 тыс. изображений глаз. При для каждого размечено положение истинной окружности — в целях обучения и проверки создаваемого метода.
-* '''Базовой алгоритм''': Для ускорения работы с изображением предлагается агрегирование данных при помощи проекций яркости. Яркость изображения — функция двух дискретных аргументов I(x,y). Её проекция на горизонтальную ось равна P(x)=\sum \limits_y I(x,y). Аналогично строятся проекции на оси с наклоном. Построив несколько проекций (две, четыре), исходя из них, можно попытаться определить положение зрачка (компактной тёмной области) при помощи эвристик и/или нейросети. Интересно оценить возможности нейросети в данной задаче.

-===Задача 55 ===
-* '''Название''': Поиск границ радужки методом круговых проекций
-* '''Задача''': Дано монохромное растровое изображение глаза, см. примеры (https://cloud.mail.ru/public/2DBu/5c6F6e3LC). Также известно приблизительное положение центра зрачка. Слово «приблизительное» означает то, вычисленный центр зрачка отстоит от истинного не более чем на половину его истинного радиуса. Необходимо определить приблизительные положения окружностей, аппроксимирующих зрачок и радужку. Алгоритм должен быть очень быстрым.
-* '''Данные''': около 200 тыс. изображений глаз. При для каждого размечено положение истинной окружности — в целях обучения и проверки создаваемого метода.
-* '''Базовой алгоритм''': Для ускорения работы с изображением предлагается агрегирование данных при помощи круговых проекций яркости. Круговая проекция — функция, зависящая от радиуса, значение которой P(r) равно интегралу направленного градиента яркости изображения по окружности радиуса r (или по дуге окружности). Пример для одной дуги (правой четверти) и для четырёх дуг. Построив сколько-то круговых проекций, исходя из них, можно попытаться определить положение внутренней и внешней границ радужки (кольца) при помощи эвристик и/или нейросети.

Примером может служить сложносоставное поведение человека: при рассмотрении данных IMU-датчиков можно выдвинуть гипотезу: есть исходный сигнал, есть агрегаты “элементарных действий” и есть агрегаты “действий” человека. Каждый из указанных уровней абстракции можно выделить и оперировать именно им.<br />Для того, чтобы проводить точное распознавание последовательности действий возможно применять метрические методы (например DTW, как способ, устойчивый к временным сдвигам). Для более точного качества выравнивания временной шкалы возможно проводить выравнивание на разных уровнях абстракций.<br />Предлагается исследовать такой иерархический подход к выравниванию последовательностей, основанный на возможности применения алгоритмов выравнивания к объектам разной структуры, имея функцию расстояние на них.

Тогда объектом на нижнем уровне абстракции служит исходный сигнал. На втором уровне - сигнал из скрытого слоя модели (построенной на объектах нижнего уровня), размерность которого много меньше, а верхнего слоя - сигнал из скрытого слоя модели (построенной на объектах среднего уровня).<br />При этом DTW вычисляется отдельно между нижними, между средними и между верхними уровнями, но формирование объектов для расчета расстояния осуществляется с учетом выравнивающего пути между объектами предыдущего уровня.<br />Данный метод рассматривается как способ повышения интерпретируемости процедуры выравнивания и точности классификации действия в связи с переходом к более высокоуровневым паттернам. Кроме того, ожидается существенное увеличение скорости работы.

As secondary structure often defines functions, knowing RNAs secondary structure may help investigate functions of novel RNA molecules.

+* '''Problem:''' RNA secondary structure is an important feature which defines RNA functional properties. Its importance can be illustrated by the fact, that it is evolutionary preserved and some types of functional RNAs always * have the same secondary structure, for example all tRNAs fold into cloverleaf.  As secondary structure often defines functions, knowing RNAs secondary structure may help investigate functions of novel RNA molecules. RNA folding is not as easy as DNA folding, because RNA is single stranded molecule which forms complicated base-pairing interactions, while DNA mostly exists as fully base paired double helices. Current methods of RNA structure prediction rely on experimentally evaluated thermodynamic rules, but with thermodynamics alone only 80% of structures can be accurately predicted. We propose an AI-driven method for predicting RNA secondary structure inspired by neural machine translation model.

However, this flexibility makes The problem of setting the coefficients very difficult. This tuning can be greatly simplified by using the relative regularization coefficients mechanism and automatic selection of N-grams. We need to test the hypothesis that there is a universal set of relative regularization coefficients that gives "reasonably good" results on a wide class of problems. Several datasets are given with some external quality criterion (for example, classification of documents into categories or ranking). We find the best parameters for a particular dataset, giving the "locally the best model". We find the bigARTM initialization algorithm that produces thematic models with quality comparable to the "locally best model" on its dataset. Comparability criterion in quality: on this dataset, the quality of the "universal model" is no more than 5% worse than that of the "locally best model".

-=== Задача 47 ===
-* '''Название''': Deep learning for RNA secondary structure prediction
-* '''Задача''': RNA secondary structure is an important feature which defines RNA functional properties. Its importance can be illustrated by the fact, that it is evolutionary preserved and some types of functional RNAs always * have the same secondary structure, for example all tRNAs fold into cloverleaf.  As secondary structure often defines functions, knowing RNAs secondary structure may help investigate functions of novel RNA molecules. RNA folding is not as easy as DNA folding, because RNA is single stranded molecule which forms complicated base-pairing interactions, while DNA mostly exists as fully base paired double helices. Current methods of RNA structure prediction rely on experimentally evaluated thermodynamic rules, but with thermodynamics alone only 80% of structures can be accurately predicted. We propose an AI-driven method for predicting RNA secondary structure inspired by neural machine translation model.

-=== Задача 4 ===
-* '''Название:''' Автоматическая настройка параметров АРТМ под широкий класс задач.
-* '''Задача:''' Открытая библиотека bigARTM позволяет строить тематические модели, используя широкий класс возможных регуляризаторов. Однако такая гибкость приводит к тому, что задача настройки коэффициентов оказывается очень сложной. Эту настройку можно значительно упростить, используя механизм относительных коэффициентов регуляризации и автоматический выбор N-грамм. Нужно проверить гипотезу о том, что существует универсальный набор относительных коэффициентов регуляризации, дающий "достаточно хорошие" результаты на широком классе задач. Дано несколько датасетов с каким-то внешним критерием качества (например, классификация документов по категориям или ранжирование). Находим лучшие параметры для конкретного датасета, дающие "локально лучшую модель". Находим алгоритм инициализации bigARTM, производящий тематические модели с качеством, сравнимым с "локально лучшей моделью" на её датасете. Критерий сравнимости по качеству: на данном датасете качество "универсальной модели" не более чем на 5% хуже, чем у "локально лучшей модели".

-* '''Название:''' Автоматическая настройка параметров АРТМ под широкий класс задач.
+* '''Title:''' Investigation of reference objects in the problem of metric classification of time series.
-* '''Задача:''' Открытая библиотека bigARTM позволяет строить тематические модели, используя широкий класс возможных регуляризаторов. Однако такая гибкость приводит к тому, что задача настройки коэффициентов оказывается очень сложной. Эту настройку можно значительно упростить, используя механизм относительных коэффициентов регуляризации и автоматический выбор N-грамм. Нужно проверить гипотезу о том, что существует универсальный набор относительных коэффициентов регуляризации, дающий "достаточно хорошие" результаты на широком классе задач. Дано несколько датасетов с каким-то внешним критерием качества (например, классификация документов по категориям или ранжирование). Находим лучшие параметры для конкретного датасета, дающие "локально лучшую модель". Находим алгоритм инициализации bigARTM, производящий тематические модели с качеством, сравнимым с "локально лучшей моделью" на её датасете. Критерий сравнимости по качеству: на данном датасете качество "универсальной модели" не более чем на 5% хуже, чем у "локально лучшей модели".
+* '''Problem description:''' The DTW function is the distance between two time series that can be non-linearly warped relative to each other. It looks for the best alignment between two objects, so it can be used in a metric object classification problem. One of the methods for solving the problem of metric classification is measuring distances to reference objects and using the vector of these distances as an indicative description of the object. The DBA method is an algorithm for constructing centroids (reference objects) for time series based on the DTW distance. When plotting the distance between the time series and the centroid, different pairs of values (eg peak values) are more specific to one of the classes, and the impact of such coincidences on the distance value should be higher.

+It is necessary to explore various ways of constructing reference objects, as well as determining their optimal number. The criterion is the quality of the metric classifier in The problem. In the DBA method, for each centroid, it is proposed to create a weight vector that demonstrates the "significance" of the measurements of the centroid, and use it in the modified weighted-DTW distance function.

-=== Задача 2 ===
-* '''Название:''' Исследование опорных объектов в задаче метрической классификации временных рядов.
-* '''Задача:''' Функция DTW - это расстояние между двумя временными рядами, которые могут быть нелинейно деформированы друг относительно друга. Она ищет наилучшее выравнивание между двумя объектами, поэтому ее можно использовать в задаче метрической классификации объектов.  Один из методов решения задачи метрической классификации - измерение расстояний до опорных объектов и использование вектора этих расстояний в качестве признакового описания объекта. Метод DBA - это алгоритм построения центроидов (опорных объектов) для временных рядов на основе расстояния DTW. При построении расстояния между временным рядом и центроидом различные пары значений (например пиковые значения) более характерны для одного из классов, и влияние таких совпадений на значение расстояния должна быть выше.
-Необходимо исследовать различные способы построения опорных объектов, а также определение их оптимального числа. Критерием является качество работы метрического классификатора в задаче. В методе DBA для каждого центроида предлагается создавать вектор весов, который демонстрирует "значимость" измерений центроида, и использовать его в модифицированной функции расстояния weighted-DTW.

-* '''Задача''': С точки зрения биоинформатики, задача заключается в оценке свободной энергии связывания белка с маленькой молекулой (лигандом): наилучший лиганд в своем наилучшем положении имеет ''наименьшую свободную энергию'' взаимодействия с белком.

-* '''Базовый алгоритм''': [https://hal.inria.fr/hal-01591154/] В задаче классификации мы использовали алгоритм, похожий на линейный SVM, связь которого с оценкой энергии, выходящей за рамки задачи классификации, описана в указанной выше статье. В задаче регрессии можно использовать различные функции потерь.
+* '''Basic algorithm''': [https://hal.inria.fr/hal-01591154/] In the classification problem, we used an algorithm similar to linear SVM, whose relationship with the energy estimate is beyond the scope of the classification problem, described in the above article. Various loss functions can be used in a regression problem.
-* '''Решение''': Необходимо связать использованную ранее оптимизационную задачу с задачей регрессии и решить стандартными методами. Для проверки работы алгоритма будет использована кросс-валидация. Есть отдельный тестовый сет, состоящий из (1) 195 комплексов белков и лигандов, для которых нужно найти наилучшую позу лиганда (алгоритм получения положений лиганда отличается от используемого при обучении), (2) комплексов белков и лигандов, для нативных поз которых нужно предсказать энергию связывания, и (3) 65 белков, для которых нужно найти наиболее сильно связывающийся лиганд.
+* '''Solution:''' It is necessary to connect the previously used optimization problem with the regression problem and solve it using standard methods. Cross-validation will be used to check the operation of the algorithm. There is a separate test set consisting of (1) 195 complexes of proteins and ligands, for which it is necessary to find the best ligand pose (the algorithm for obtaining ligand positions differs from that used in training), (2) complexes of proteins and ligands, for which native poses it is necessary to predict the energy binding, and (3) 65 proteins for which the most strongly binding ligand is to be found.
-* '''Новизна''': В первую очередь, интерес представляет ''объединение задач классификации и регрессии. Правильная оценка качества связывания белка и лиганда используется при разработке лекарства для поиска молекул, наиболее сильно взаимодействующих с исследуемым белком. Использование описанной выше задачи классификации для предсказания энергии связывания приводит к недостаточно высокой корреляции предсказаний с экспериментальными значениями, в то время как использование одной лишь задачи регрессии приводит к переобучению.
+* '''Novelty:''' First of all, the interest is ''combining classification and regression problems. The correct assessment of the quality of protein and ligand binding is used in drug development to search for molecules that interact most strongly with the protein under study. Using the classification problem described above to predict the binding energy results in an insufficiently high correlation of predictions with experimental values, while using the regression problem alone leads to overfitting.

For an already existing example of the answer to questions 1-3, see the works of A. A. Varfolomeeva.

+* '''Base algorithm:'''  Described in [1]. Developed in the work of the 974 group team. It is proposed to use their code and experiment.
-* '''Решение''': Предлагается попробовать повторить эксперимент А. А. Варфоломеевой для другого структурного описания, чтобы понять, что происходит. Суперпозиция алгебраических функций задает ордерево, на вершинах которого заданы метки соответствующих алгебраических функций или переменных. Поэтому структурным описанием такой суперпозиции может являться ее DFS-code. Это строка, состоящая из меток вершин, записанных в порядке обхода дерева поиском в глубину. Зная арности соответствующих алгебраических функций, можем любой такой DFS-code восстановить за O(n) и получить обратно суперпозицию функций. На множестве подобных строковых описаний предлагается искать то строковое описание, которое будет соответствовать оптимальной модели.
+* '''Solution:''' It is proposed to try to repeat the experiment of A. A. Varfolomeeva for a different structural description in order to understand what is happening. The superposition of algebraic functions defines an ortree, on the vertices of which the labels of the corresponding algebraic functions or variables are given. Therefore, the structural description of such a superposition can be its DFS-code. This is a string consisting of vertex labels, written in the order in which the tree is traversed by depth-first search. Knowing the arities of the corresponding algebraic functions, we can restore any such DFS-code in O(n) and get back the superposition of functions. On the set of similar string descriptions, it is proposed to search for the string description that will correspond to the optimal model.

-* Название: Задача поиска символов в изображениях
+* Name: The problem of searching characters in images
-* Задача: Данная задача в одном из вариантов постановки может быть сведена к двум последовательным операциям: 1) поиск объектов на изображении и определение их класса 2) поиск в базе данных информации о символическом смысле найденных объектов. Основная сложность решения задачи заключена в поиске объектов на изображении. Однако следующая классификация также может быть затруднительной в связи с тем, что изображение объекта может быть неполным, необычно стилизованным и т.п.
+* '''Problem description:''' This The problem in one of the formulation options can be reduced to two sequential operations: 1) searching for objects in the image and determining their class 2) searching the database for information about the symbolic meaning of the found objects. The main difficulty in solving the problem lies in the search for objects in the image. However, the following classification may also be difficult due to the fact that the image of the object may be incomplete, unusually stylized, and the like.

The neural network is considered as a computational graph, the edges of which are primitive functions, and the vertices are intermediate representations of the sample obtained under the action of these functions. It is required to choose a subgraph of the model, in which the final neural network will give an acceptable classification quality with a small number of parameters.

+===5. 2018===
+* '''Title:''' Finding paraphrases.
+* '''Problem description:''' Paraphrases are different variations of the same and the same text, identical in meaning, but differing lexically and grammatically, for example: "Where did the car go" and "Which direction did the car go". The problem of detecting paraphrases is to select clusters in a set of texts, such that each cluster contains only paraphrases of the same and the same sentence. The easiest way to extract paraphrases is to cluster texts, where each text is represented by a "bag of words".
+* '''Data:''' There are open datasets of questions for testing and training on kaggle.com, there are open datasets for testing from semeval conferences.
+* '''Base algorithm:'''  Use one of the document clustering algorithms to extract paraphrases, where each document is represented by a bag of words or tf-idf.
+* '''Solution:''' Use neural network architectures to search for paraphrases, use phrases extracted with parsers as features, use multilevel clustering.
+* '''Novelty:''' Lack of implementations for the Russian language that will use parsers for a similar The problem, all current solutions are quite "simple".
+* '''Authors:''' Artyom Popov.

-* '''Название:''' Прогнозирование направления движения цены биржевых инструментов по новостному потоку.
+* '''Title:''' On conformational changes of proteins using collective motions in torsion angle space and L1 regularization.
-* '''Задача:''' Построить и исследовать модель прогнозирования направления движения цены. Задано множество новостей S и множество временных меток T, соответствующих времени публикации новостей из S. 2. Временной ряд P, соответствующий значению цены биржевого инструмента, и временной ряд V, соответствующий объему продаж по данному инструменту, за период времени T'. 3. Множество T является подмножеством периода времени T'. 4. Временные отрезки w=[w0, w1], l=[l0, l1], d=[d0, d1], где w0 < w1=l0 < l1=d0 < d1. Требуется спрогнозировать направление движения цены биржевого инструмента в момент времени t=d0 по новостям, вышедшим в период w.
+* '''Problem description:''' Torsion angles are the most natural degrees of freedom for describing motions of polymers, such as proteins. This is because bond lengths and bond angles are heavily constrained by covalent forces. Thus, multiple attempts have been done to describe protein dynamics in the torsion angle space. For example, one of us has developed an elastic network model (ENM) [1] in torsion angle space called Torsional Network Model (TNM) [2]. Functional conformational changes in proteins can be described in the Cartesian space using just a subset of collective coordinates [3], or even a sparse representation of these [4]. The latter requires a solution of a LASSO optimization problem [5]. The goal of the current project is to study if a sparse subset of collective coordinates in the torsion subspace can describe functional conformational changes in proteins. This will require a solution of a ridge regression problem with a L1 regularization constraint. The starting point will be the LASSO formulation.
-* '''Данные:'''

-=== Задача 2 ===
-* '''Название:''' Исследование опорных объектов в задаче метрической классификации временных рядов.
-* '''Задача:''' Функция DTW - это расстояние между двумя временными рядами, которые могут быть нелинейно деформированы друг относительно друга. Она ищет наилучшее выравнивание между двумя объектами, поэтому ее можно использовать в задаче метрической классификации объектов.  Один из методов решения задачи метрической классификации - измерение расстояний до опорных объектов и использование вектора этих расстояний в качестве признакового описания объекта. Метод DBA - это алгоритм построения центроидов (опорных объектов) для временных рядов на основе расстояния DTW. При построении расстояния между временным рядом и центроидом различные пары значений (например пиковые значения) более характерны для одного из классов, и влияние таких совпадений на значение расстояния должна быть выше.
-Необходимо исследовать различные способы построения опорных объектов, а также определение их оптимального числа. Критерием является качество работы метрического классификатора в задаче. В методе DBA для каждого центроида предлагается создавать вектор весов, который демонстрирует "значимость" измерений центриода, и использовать его в модифицированной функции расстояния weighted-DTW.

-Исследование литературы и комбинация up-to-date методов.

-* '''Задача:''' Характерным многомерным временным рядом является траектория точки в 3х-мерном пространстве. Две траектории необходимо выравнивать оптимальным образом друг относительно друга. Для этого используется расстояние DTW между двумя временными рядами. В классическом представлении DTW строится между одномерными временными рядами. Необходимо ввести различные модификации алгоритма для работы со временными рядами высокой размерности: траекториями, кортикограммами.

-=== Задача 4 ===
-* '''Название:''' Автоматическая настройка параметров АРТМ под широкий класс задач.
-* '''Задача:''' Открытая библиотека bigARTM позволяет строить тематические модели, используя широкий класс возможных регуляризаторов. Однако такая гибкость приводит к тому, что задача настройки коэффициентов оказывается очень сложной. Эту настройку можно значительно упростить, используя механизм относительных коэффициентов регуляризации и автоматический выбор N-грамм. Нужно проверить гипотезу о том, что существует универсальный набор относительных коэффициентов регуляризации, дающий "достаточно хорошие" результаты на широком классе задач. Дано несколько датасетов с каким-то внешним критерием качества (например, классификация документов по категориям или ранжирование). Находим лучшие параметры для конкретного датасета, дающие "локально лучшую модель". Находим алгоритм инициализации bigARTM, производящий тематические модели с качеством, сравнимым с "локально лучшей моделью" на её датасете. Критерий сравнимости по качеству: на данном датасете качество "универсальной модели" не более чем на 5% хуже, чем у "локально лучшей модели".

Задача детектирования парафразов заключается в выделении в множестве текстов кластеров, таких что в каждом кластере содержатся только парафразы одного и того же предложения.

Until recently, it was generally accepted that these are second-order methods (using the second derivatives of the function being optimized). However, at the beginning of 2018 Yu.E. Nesterov [1] proposed an efficient third-order method in the theory, which works according to almost optimal estimates.

It is worth comparing both by the number of iterations and by the total running time.

-=== Задача 13 ===
-* '''Название''': Deep learning for RNA secondary structure prediction
-* '''Задача''': RNA secondary structure is an important feature which defines RNA functional properties. Its importance can be illustrated by the fact, that it is evolutionary preserved and some types of functional RNAs always have the same secondary structure, for example all tRNAs fold into cloverleaf.  As secondary structure often defines functions, knowing RNAs secondary structure may help investigate functions of novel RNA molecules. RNA folding is not as easy as DNA folding, because RNA is single stranded molecule which forms complicated base-pairing interactions, while DNA mostly exists as fully base paired double helices. Current methods of RNA structure prediction rely on experimentally evaluated thermodynamic rules, but with thermodynamics alone only 80% of structures can be accurately predicted. We propose an AI-driven method for predicting RNA secondary structure inspired by neural machine translation model.

-===Задача 14===
-* '''Название''': Deep Learning for reliable detection of tandem repeats in 3D protein structures [[Media:Strijov_3D_CNN.pdf|подробнее в PDF]]
-* '''Задача''': Deep learning algorithms pushed computer vision to a level of accuracy comparable or higher than a human vision. Similarly, we believe that it is possible to recognize the symmetry of a 3D object with a very high reliability, when the object is represented as a density map. The optimization problem includes i) multiclass classification of 3D data. The output is the order of symmetry. The number of classes is ~10-20 ii)	multioutput regression of 3D data. The output is the symmetry axis (a 3-vector). The input data are typically 24x24x24 meshes. The total amount of these meshes is of order a million. Biological motivation : Symmetry is an important feature of protein tertiary and quaternary structures that has been associated with protein folding, function, evolution, and stability. Its emergence and ensuing prevalence has been attributed to gene duplications, fusion events, and subsequent evolutionary drift in sequence. Methods to detect these symmetries exist, either based on the structure or the sequence of the proteins, however, we believe that they can be vastly improved.
-* '''Данные''': Synthetic data are obtained by ‘symmetrizing’ folds from top8000 library (http://kinemage.biochem.duke.edu/databases/top8000.php).

-* '''Базовый алгоритм''': A prototype has already been created using the Tensorflow framework [4], which is capable to detect the order of cyclic structures with about 93% accuracy. The main goal of this internship is to optimize the topology of the current neural network prototype and make it rotational and translational invariant with respect to input data. [4] [https://www.tensorflow.org/]
-* '''Решение''': The network architecture needs to be modified according to the invariance properties (most importantly, rotational invariance). Please see the links below [https://hal.inria.fr/hal-01630265/document], [https://arxiv.org/pdf/1706.03078.pdf] The code is written using the Tensorflow library, and the current model is trained on a single GPU (Nvidia Quadro 4000)of a desktop machine.
-* '''Новизна''': Applications of convolutional networks to 3D data are still very challenging due to large amount of data and specific requirements to the network architecture. More specifically, the models need to be rotationally and transnationally invariant, which makes classical 2D augmentation tricks loosely applicable here. Thus, new models need to be developed for 3D data.

-В задаче классификации мы использовали алгоритм, похожий на линейный SVM, связь которого с оценкой энергии, выходящей за рамки задачи классификации, описана в указанной выше статье. В задаче регрессии можно использовать различные функции потерь.
-* '''Решение''': Необходимо связать использованную ранее оптимизационную задачу с задачей регрессии и решить стандартными методами. Для проверки работы алгоритма будет использована кросс-валидация.
-Есть отдельный тестовый сет, состоящий из (1) 195 комплексов белков и лигандов, для которых нужно найти наилучшую позу лиганда (алгоритм получения положений лиганда отличается от используемого при обучении), (2) комплексов белков и лигандов, для нативных поз которых нужно предсказать энергию связывания, и (3) 65 белков, для которых нужно найти наиболее сильно связывающийся лиганд.
-* '''Новизна''': В первую очередь, интерес представляет ''объединение задач классификации и регрессии.
-Правильная оценка качества связывания белка и лиганда используется при разработке лекарства для поиска молекул, наиболее сильно взаимодействующих с исследуемым белком. Использование описанной выше задачи классификации для предсказания энергии связывания приводит к недостаточно высокой корреляции предсказаний с экспериментальными значениями, в то время как использование одной лишь задачи регрессии приводит к переобучению.

Нестеров [1] предложил в теории эффективный метод третьего порядка, который работает почти по оптимальным оценкам. В пособии [3] в упражнении 1.3 описан пример "плохой" выпуклой функции, предложенной Ю.Е.

+* '''Title:''' Fractal analysis and synthesis of optical images of sea waves
-* '''Задача:''' Разнообразные физические процессы и явления изучаются с помощью изображений, получаемых дистанционно. Важной задачей является получение адекватной информации об интересующих процессах и явлениях путём измерения определённых характеристик изображений. Линии равной яркости (изолинии) на изображениях многих природных объектов являются фрактальными, то есть представляют собой множества точек, которые не могут быть представлены линиями конечной длины и занимают промежуточное положение между линиями и двумерными плоскими фигурами. Такие множества характеризуются фрактальной размерностью D, которая обобщает классическое понятие размерности множества и может принимать дробные значения. Для уединённой точки на изображении D=0, для гладкой кривой D=1, для плоской фигуры D=2. Фрактальная изолиния имеет размерность 1<D<2. Алгоритм расчёта D приведён, например, в [1]. Фрактальная размерность изолиний морской поверхности, может служить для оценки пространственных спектров морских волн по данным дистанционного зондирования [1]. Задача состоит в следующем. Необходимо провести исследование численными методами зависимости между характеристиками пространственных спектров морских волн и фрактальной размерностью спутниковых изображений Земли в области солнечного блика. Для исследования следует использовать метод численного синтеза оптических изображений морского волнения, описанный в [2]. Численное моделирование должно быть при различных характеристиках морских волн, а также при различных положениях Солнца и пространственном разрешении изображений.
+* '''Problem description:''' A variety of physical processes and phenomena are studied with the help of images obtained remotely. An important The problem is to obtain adequate information about the processes and phenomena of interest by measuring certain image characteristics. Lines of equal brightness (isolines) on the images of many natural objects are fractal, that is, they are sets of points that cannot be represented by lines of finite length and occupy an intermediate position between lines and two-dimensional flat figures. Such sets are characterized by the fractal dimension D, which generalizes the classical concept of the dimension of a set and can take fractional values. For a solitary point on the image D=0, for a smooth curve D=1, for a flat figure D=2. The fractal isoline has the dimension 1<D<2. The algorithm for calculating D is given, for example, in [1]. The fractal dimension of the sea surface isolines can serve to estimate the spatial spectra of sea waves according to remote sensing data [1]. The problem is as follows. It is necessary to conduct a numerical study of the relationship between the characteristics of the spatial spectra of sea waves and the fractal dimension of satellite images of the Earth in the solar glare region. For the study, the method of numerical synthesis of optical images of sea waves, described in [2], should be used. Numerical modeling should be done with different characteristics of sea waves, as well as with different positions of the Sun and spatial resolution of images.

+* '''Name''' Entropy maximization for various types of image transformations
-* '''Задача:''' Паншарпенинг — это алгоритм повышения разрешения мультиспектральных изображений с использованием опорного изображения. Задача паншарпенинга формулируется следующим образом: имея панхроматическое изображение требуемого разрешения и мультиспектральное изображение пониженного разрешения, требуется восстановить мультиспектральное изображение в пространственном разрешении панхроматического. Из эмпирических наблюдений, основанных на большом количестве снимков высокого разрешения, известно, что пространственная вариативность интенсивности отраженного излучения для объектов одной природы гораздо больше, чем вариативность их спектра. Другими словами, можно наблюдать, что спектр отраженного излучения однороден в границах одного объекта, в то время как даже внутри одного объекта интенсивность отраженного излучения варьируется. На практике хороших результатов можно достигнуть, используя упрощенный подход, при котором считается, что если интенсивность соседних областей значительно отличается, то, вероятно, эти области принадлежат разным объектам с разными отраженными спектрами. На этом основан разработанный вероятностный алгоритм повышения разрешения мультиспектральных изображений с использованием опорного изображения [1]
+* '''Problem description:''' Pansharpening is an algorithm for upscaling multispectral images using a reference image. The problem of pansharpening is formulated as follows: having a panchromatic image of the required resolution and a multispectral image of reduced resolution, it is required to restore the multispectral image in the spatial resolution of the panchromatic one. From empirical observations based on a large number of high-resolution images, it is known that the spatial variability of the reflected radiation intensity for objects of the same nature is much greater than the variability of their spectrum. In other words, one can observe that the spectrum of reflected radiation is homogeneous within the boundaries of one object, while even within one object the intensity of reflected radiation varies. In practice, good results can be achieved using a simplified approach, in which it is assumed that if the intensity of neighboring regions differ significantly, then these regions probably belong to different objects with different reflected spectra. This is the basis for the developed probabilistic algorithm for increasing the resolution of multispectral images using a reference image [1]

Show that entropy can serve as an indicator of the loss of information contained in the image during transformations over it. Formulation of the inverse problem for image restoration: Condition 1: Correspondence of the intensity (at each point) of the restored image with the intensity of the panchromatic image. Condition 2: Correspondence of the low-frequency component of the reconstructed image with the original multispectral image. Condition 3: Homogeneity (similarity) of the spectrum within one object and the assumption of an abrupt change in the spectrum at the border of two homogeneous regions. Condition 4: Under the first three conditions, the local entropy of the reconstructed image must be maximized.

-* '''Название:''' Автоматическое детектирование и распознавание объектов на изображениях
-* '''Задача:''' Автоматическое детектирование и распознавание объектов на изображениях и видео является одной из основных задач компьютерного зрения. Как правило, эти задачи разбиваются на несколько подзадач: предобработка, выделение характерных свойств изображения объекта и классификация. Этап предобработки обычно включает некоторые операции с изображением, такие как фильтрация, выравнивание яркости, геометрические корректирующие преобразования для облегчения устойчивого выделения признаков.
-Под характерными свойствами изображения объекта понимается некоторый набор признаков, приближённо описывающий интересующий объект. Признаки можно разбить на два класса: локальные и интегральные. Преимуществом локальных признаков является их универсальность, инвариантность по отношению к неравномерным изменениям яркости и освещённости, но они не уникальны. Интегральные признаки, характеризующие изображение объекта в целом, не устойчивы к изменению структуры объекта и сложным условиям освещения. Существует комбинированный подход — использование локальных признаков в качестве элементов интегрального описания, когда искомый объект моделируется набором областей, каждая из которых характеризуется своим набором признаков — локальным текстурным дескриптором. Совокупность таких дескрипторов характеризует объект в целом.
-Под классификацией понимают определение принадлежности объекта к тому или иному классу путём анализа вектора признаков, полученного на предыдущем этапе, разделения признакового пространства на подобласти, указывающие на соответствующий класс. Существует множество подходов к классификации: нейросетевые, статистические (Байеса, регрессия, Фишера и др.), решающие деревья и леса, метрические (ближайшие К-соседей, парзеновские окна и&nbsp;т.&nbsp;д.) и ядерные (SVM, RBF, метод потенциальных функций), композиционные (AdaBoost). Для задачи обнаружения объекта на изображении оценивается принадлежность двум классам — классу изображений, содержащих объект, и классу изображений, не содержащих объект (изображениям фона).

+The characteristic properties of an image of an object are understood as a set of features that approximately describe the object of interest. Features can be divided into two classes: local and integral. The advantage of local features is their versatility, invariance with respect to uneven changes in brightness and illumination, but they are not unique. Integral features that characterize the image of the object as a whole are not resistant to changes in the structure of the object and difficult lighting conditions. There is a combined approach - the use of local features as elements of an integral description, when the desired object is modeled by a set of areas, each of which is characterized by its own set of features - a local texture descriptor. The totality of such descriptors characterizes the object as a whole.

-* Решение: Одним из вариантов обобщения алгоритма HOG может быть использование вместо линейного алгоритма SVM другого классификатора, например какой-либо нейронной сети. Предлагается для основы экспериментов использовать библиотеку OpenCV, в которой реализован алгоритм HOG и классификатор SVM. Нужно проанализировать исходный код реализации HOG, формализовать внутреннюю структуру вектора HOG дескриптора в форме трехмерного тензора — две пространственные и одна спектральная размерности. Необходимо написать программу чтения базы INRIA, обучения по ней метода линейного SVM на HOG-дескрипторах, сбора статистики детектирования и построения DET-графиков FAR/FRR. Необходимо на основе какой-либо системы обучения нейросети (например, mxnet) собрать неглубокую (не более 2-3 сверточных слоев) сверточную нейросеть известной архитектуры, обучить ее на базе INRIA и на тензорных дескрипторах HOG, построить соответствующие графики FAR/FRR.
+* '''Solution:''' One of the options for generalizing the HOG algorithm can be to use another classifier instead of the linear SVM algorithm, for example, some kind of neural network. It is proposed to use the OpenCV library for the basis of experiments, which implements the HOG algorithm and the SVM classifier. It is necessary to analyze the source code of the HOG implementation, formalize the internal structure of the descriptor HOG vector in the form of a three-dimensional tensor — two spatial and one spectral dimensions. It is necessary to write a program for reading the INRIA base, learning the linear SVM method on HOG descriptors from it, collecting detection statistics and plotting FAR/FRR DET plots. Based on some neural network training system (for example, mxnet), it is necessary to assemble a shallow (no more than 2-3 convolutional layers) convolutional neural network of known architecture, train it on the basis of INRIA and on HOG tensor descriptors, build the corresponding FAR / FRR graphs.
-* Новизна: Разработка вычислительно простых методов для выделения максимально информативных признаков в задачах распознавания является актуальной в области создания встроенных систем, обладающих малыми вычислительными ресурсами. Использование небольшого количества наиболее информативных дескрипторов может уменьшить вычислительную сложность, по сравнению с использованием большой композиции простых признаков, например в глубокой сверточной нейросети. Обычно классификаторы используют HOG дескриптор как вектор в целом, однако при этом теряется информация о локальной пространственной структуре и спектре признаков. Новизна заключается в использовании свойства локальности блоков в HOG дескрипторе и представление HOG в виде трехмерного тензора. Использование этой информации позволяет достичь устойчивости детектирования к перекрытию пешехода.
+* '''Novelty:''' The development of computationally simple methods for extracting the most informative features in recognition The problems is relevant in the field of creating embedded systems with low computing resources. Using a small number of the most informative descriptors can reduce computational complexity compared to using a large composition of simple features, such as in a deep convolutional neural network. Typically, classifiers use the HOG descriptor as a vector as a whole, however, information about the local spatial structure and feature spectrum is lost. The novelty lies in the use of the block locality property in the HOG descriptor and the representation of the HOG as a 3D tensor. The use of this information makes it possible to achieve detection resistance to pedestrian overlap.

-* '''Задача''': Deep learning algorithms pushed computer vision to a level of accuracy comparable or higher than a human vision. Similarly, we believe that it is possible to recognize the symmetry of a 3D object with a very high reliability, when the object is represented as a density map. The optimization problem includes i) multiclass classification of 3D data. The output is the order of symmetry. The number of classes is ~10-20 ii)	multioutput regression of 3D data. The output is the symmetry axis (a 3-vector). The input data are typically 24x24x24 meshes. The total amount of these meshes is of order a million. Biological motivation : Symmetry is an important feature of protein tertiary and quaternary structures that has been associated with protein folding, function, evolution, and stability. Its emergence and ensuing prevalence has been attributed to gene duplications, fusion events, and subsequent evolutionary drift in sequence. Methods to detect these symmetries exist, either based on the structure or the sequence of the proteins, however, we believe that they can be vastly improved.

+* '''Base algorithm:'''  A prototype has already been created using the Tensorflow framework [4], which is capable of detecting the order of cyclic structures with about 93% accuracy. The main goal of this internship is to optimize the topology of the current neural network prototype and make it rotational and translational invariant with respect to input data. [4] [https://www.tensorflow.org/]
-* '''Решение''': The network architecture needs to be modified according to the invariance properties (most importantly, rotational invariance). Please see the links below [https://hal.inria.fr/hal-01630265/document],

-* '''Новизна''': Applications of convolutional networks to 3D data are still very challenging due to large amount of data and specific requirements to the network architecture. More specifically, the models need to be rotationally and transnationally invariant, which makes classical 2D augmentation tricks loosely applicable here. Thus, new models need to be developed for 3D data.

+* '''Basic algorithm''': solution [3] or vector representations obtained using seq2seq[].
-* '''Решение''': в задаче предлагается обучить векторные представления для фраз, используя механизм attention и метод частичного обучения. В качестве внутреннего функционала качества предлагается использовать усовершенствованную функцию ошибки из [2]. В качестве прикладной задачи можно рассмотреть задачу детектирования перефразирований и сентимент-анализ. Причем, исходя из результатов, полученный в [1], можно сделать предположение о том, что механизм attention в большей степени влияет на получение универсальных векторов для фраз, чем архитектура сети. Предлагается протестировать эту гипотезу с использованием двух различных архитектур - стандартной рекуррентной и feed-forward сети.
+* '''Solution:''' in The problem it is proposed to train vector representations for phrases using the attention and partial learning mechanism. As an internal quality functional, it is proposed to use the improved error function from [2]. As an applied problem, we can consider the problem of detecting paraphrases and sentiment analysis. Moreover, based on the results obtained in [1], it can be assumed that the attention mechanism has a greater influence on obtaining universal vectors for phrases than the network architecture. It is proposed to test this hypothesis using two different architectures - a standard recurrent and feed-forward network.

-* '''Задача''': Неформально: есть набор временных рядов определенной частоты (s1), причем интересующая нас информация различима и при меньшей частоте дискретизации (например, отсчеты происходят каждую миллисекунду, а интересующие нас события происходят на интервале 0.1 с). Данные ряды интегрируются, снижая частоту в 10 раз (т.е. каждые 10 значений просто суммируются) и получается набор временных рядов s2.Предлагается найти такие преобразования над временным рядом, зависящие от частоты, что временные ряды высокой частоты s1и более низкой частоты s2 будут описываться одинаково. Формально: Задан набор временных рядов s1, ..., sNSс высокой частотой дискретизации 1.

-* '''Новизна''':  Для временных рядов отсутствует “общепринятый подход” к анализу, в отличие, например, от анализа изображений. Если посмотреть на проблему отвлеченно, сейчас кот определяется так же хорошо, как и кот, занимающий вдвое меньшее пространство на изображении. Напрашивается аналогия с временными рядами. Тем более, природа данных в картинках и во временных рядах похожа: в картинках иерархия между значениями есть по двум осям (x и y), а во временных рядах - по одной - по оси времени. Гипотеза заключается в том, что сходные с анализом изображений методы позволят получить качественные результаты. Полученное признаковое представление может в дальнейшем использоваться для классификации и предсказания временных рядов.
+* '''Novelty:''' For time series, there is no “common approach” to analysis, in contrast, in the example, to image analysis. If you look at the problem abstractly, now the cat is defined as well as and the cat, which takes up half the space in the image. An analogy with time series suggests itself. Moreover, the nature of data in pictures and in time series is similar: in pictures there is a hierarchy between values along two axes (x and y), and in time series - one at a time - along the time axis. The hypothesis is that methods similar to image analysis will provide qualitative results. The resulting feature representation can be further used for classification and prediction of time series.

-* '''Название''': Deep learning for RNA secondary structure prediction
+* '''Title:''' Comparison of neural network and continuous morphological methods in the Text Detection The problem.
-* '''Задача''': RNA secondary structure is an important feature which defines RNA functional properties. Its importance can be illustrated by the fact, that it is evolutionary preserved and some types of functional RNAs always * have the same secondary structure, for example all tRNAs fold into cloverleaf.  As secondary structure often defines functions, knowing RNAs secondary structure may help investigate functions of novel RNA molecules. RNA folding is not as easy as DNA folding, because RNA is single stranded molecule which forms complicated base-pairing interactions, while DNA mostly exists as fully base paired double helices. Current methods of RNA structure prediction rely on experimentally evaluated thermodynamic rules, but with thermodynamics alone only 80% of structures can be accurately predicted. We propose an AI-driven method for predicting RNA secondary structure inspired by neural machine translation model.

+* '''Title:''' Classification of superpositions of movements of physical activity
+* '''Problem:''' Human behavior analysis by mobile phone sensor measurements: detect human movements from accelerometer data. The accelerometer data is a signal without precise periodicity, which contains an unknown superposition of physical models. We will consider the superposition of models: body + arm/bag/backpack.
+Classification of human activities according to measurements of fitness bracelets. According to the measurements of the accelerometer and gyroscope, it is required to determine the type of activity of the worker. It is assumed that the time series of measurements contain elementary movements that form clusters in the space of time series descriptions. (Development: The characteristic duration of movement is seconds. Time series are marked with activity type marks: work, rest. The characteristic duration of activity is minutes. It is required to restore the type of activity by the description of the time series and cluster.)

+* '''Problem:''' It is required to predict a time series using some parametric superposition of algebraic functions. It is proposed not to cost the prognostic model, but to predict it, that is, to predict the structure of the approximating superposition. A class of considered superpositions is introduced, and on the set of such structural descriptions, a search is made for a locally optimal model for the problem under consideration. The problem consists in 1) searching for a suitable structural description of the model 2) describing the search algorithm for the structure that will correspond to the optimal model 3) describing the algorithm for inverse construction of the model according to its structural description. For an already existing example of the answer to questions 1-3, see the works of A. A. Varfolomeeva.

+* '''Base algorithm:'''  Specifically, there is no basic algorithm for the proposed problem. It is proposed to try to repeat the experiment of A.A. Varfolomeeva for a different structural description in order to understand what is happening.
+* '''Solution:''' The superposition of algebraic functions defines an ortree, on the vertices of which the labels of the corresponding algebraic functions or variables are given. Therefore, the structural description of such a superposition can be its DFS-code. This is a string consisting of vertex labels, written in the order in which the tree is traversed by depth-first search. Knowing the arities of the corresponding algebraic functions, we can restore any such DFS-code in O(n) and get back the superposition of functions. On the set of similar string descriptions, it is proposed to search for the string description that will correspond to the optimal model.

-Для предсказания взаимодействия молекул друг с другом зачастую необходимо правильно описать составляющие их атомы, поставив им в соответствие некоторые типы. Для маленьких молекул доступно не так много дескрипторов: координаты и химические элементы атомов, длины связей и величины углов между ними. Используя эти признаки, мы успешно предсказываем гибридизации атомов и типы связей. При таком подходе каждый атом рассматривается «по отдельности», информация о соседних атомах, необходимая для определения типа атома, практически не используется, и типы атомов определяются с помощью проверки большого числа условий. В то же время, молекулы представимы в виде трехмерных молекулярных графов, и было бы интересно использовать это для предсказания их типов методами машинного обучения, например, с помощью CNN.
+To predict the interaction of molecules with each other, it is often necessary to correctly describe their constituent atoms by assigning certain types to them. For small molecules, not many descriptors are available: the coordinates and chemical elements of atoms, the lengths of bonds and the magnitude of the angles between them. Using these features, we successfully predict atomic hybridizations and bond types. In this approach, each atom is considered "individually", the information about neighboring atoms necessary to determine the type of an atom is practically not used, and the types of atoms are determined by checking a large number of conditions. At the same time, molecules are represented as 3D molecular graphs, and it would be interesting to use this to predict their types with machine learning methods, for example, using CNNs.
-Необходимо предсказать типы вершин и рёбер молекулярных графов :
+It is necessary to predict the types of vertices and edges of molecular graphs:
-** тип атома (тип вершины графа, около 150 классов),
+*# atom type (graph vertex type, about 150 classes),
-** гибридизацию атома (вспомогательный признак, тип вершины, 4 класса),
+*# atom hybridization (auxiliary feature, vertex type, 4 classes),
-** тип связи (вспомогательный признак, тип ребра, 5 классов).
+*# connection type (auxiliary feature, edge type, 5 classes).
-Тип атома (вершины графа) основан на информации о его гибридизации и свойствах соседних с ним атомов. Поэтому в случае успешного решения задачи классификации можно провести кластеризацию для поиска других способов определения типов атомов.
+The type of an atom (graph vertex) is based on information about its hybridization and the properties of neighboring atoms. Therefore, in the case of a successful solution of the classification problem, clustering can be carried out to find other ways to determine the types of atoms.

-Есть отдельный тестовый сет, состоящий из (1) 195 комплексов белков и лигандов, для которых нужно найти наилучшую позу лиганда (алгоритм получения положений лиганда отличается от используемого при обучении), (2) комплексов белков и лигандов, для нативных поз которых нужно предсказать энергию связывания, и (3) 65 белков, для которых нужно найти наиболее сильно связывающийся лиганд.

-* '''Новизна''': В первую очередь, интерес представляет ''объединение задач классификации и регрессии'''.
+* '''Novelty:''' First of all, the interest is ''combining classification and regression problems'''.
-Правильная оценка качества связывания белка и лиганда используется при разработке лекарства для поиска молекул, наиболее сильно взаимодействующих с исследуемым белком. Использование описанной выше задачи классификации для предсказания энергии связывания приводит к недостаточно высокой корреляции предсказаний с экспериментальными значениями, в то время как использование одной лишь задачи регрессии приводит к переобучению.
+The correct assessment of the quality of protein and ligand binding is used in drug development to search for molecules that interact most strongly with the protein under study. Using the classification problem described above to predict the binding energy results in an insufficiently high correlation of predictions with experimental values, while using the regression problem alone leads to overfitting.

+* '''Title:''' Classification of human activities according to fitness bracelet measurements.
-|-
+* '''Problem:''' According to the accelerometer and gyroscope measurements, it is required to determine the type of worker's activity. It is assumed that the time series of measurements contain elementary movements that form clusters in the space of time series descriptions. The characteristic duration of the movement is seconds. Time series are labeled with activity type labels: work, leisure. The typical duration of activity is minutes. It is required to restore the type of activity according to the description of the time series and cluster.

-* '''Задача''': В рамках решения задачи декодирования сигналов ECoG решается задача классификации движений по временным рядам показаний электродов. Инструментами для извлечения признаков из временных рядов ECoG являются коэффициенты вейвлет-преобразования исследуемого сигнала [Макарчук 2016], на основе которых для каждого электрода строится скалограмма - двумерный массив признаков в пространстве частота-время. Объединение скалограмм для каждого электрода даёт признаки временного ряда в пространственно-частотно-временной области. Построенное таким образом признаковое описание заведомо содержит мультикоррелирующие признаки и является избыточным. Требуется предложить метод снижения размерности признакового пространства.
+* '''Problem:''' As part of solving the problem of decoding ECoG signals, The problem of classifying movements by time series of electrode readings is solved. The tools for extracting features from ECoG time series are the coefficients of the wavelet transform of the signal under study [Makarchuk 2016], on the basis of which a scalogram is built for each electrode - a two-dimensional array of features in frequency-time space. Combining scalograms for each electrode gives signs of a time series in the spatio-frequency-time domain. The feature description constructed in this way obviously contains multicorrelated features and is redundant. It is required to propose a method for reducing the dimension of the feature space.

-* '''Название''': Адаптивные релаксации NP трудных задач через машинное обучение
+* '''Title:''' Adaptive relaxations of NP hard problems through machine learning
-* '''Задача''': Современные задачи оптимизации потоков мощности в энергетических сетях приводят к невыпуклым задачам оптимизации с большим количеством ограничений. Аналогичные по структуре постановки возникают также в ряде других инженерных задач и в классических задачах комбинаторной оптимизации. Традиционный подход к решению подобных NP трудных задач состоит в написании их выпуклых релаксаций (semidefinite/SDP, second order conic/SOCP, etc), имеющих как правило существенно большее множество допустимых решений, чем в исходной задаче. И последующей проекцией полученного решения в область, где выполнены ограничения исходной задачи. Во многих практических случаях, качество полученного таким образом решения невелико. Альтернативные подходы, например MILP (mixed integer linear programming) релаксации, существенно более трудоемки по времени, но приводят к более точно у ответу.
+* '''Problem:''' Modern problems of optimizing power flows in power networks lead to non-convex optimization The problems with a large number of restrictions. Statements similar in structure also arise in a number of other engineering problems and in classical The problems of combinatorial optimization. The traditional approach to solving such NP hard problems is to write their convex relaxations (semidefinite/SDP, second order conic/SOCP, etc), which usually have a much larger set of feasible solutions than in the original problem. and by the subsequent projection of the obtained solution into the region where the constraints of the original problem are satisfied. In many practical cases, the quality of the solution obtained in this way is not high. Alternative approaches, for example MILP (mixed integer linear programming) relaxation, are substantially more time consuming but result in a more accurate answer.
-Основная проблема состоит в невозможности применения известных методов для решения задач большой размерности (сети из 1000 узлов и более). Одним из ключевых препятствий является не столько размерность задачи, сколько большое число ограничений. Вместе с тем, в реальных задачах можно выделить небольшое множество ограничений такое, что множества допустимых точек в выделенном множестве и в исходном весьма близки. Это позволит заменить задачу на иную, с меньшим числом ограничений, что повысит скорость используемых алгоритмов.
+The main problem is the impossibility of using known methods for solving large-scale problems (networks of 1000 nodes and more). One of the key obstacles is not so much the dimension of the problem as a large number of restrictions. At the same time, in real The problems it is possible to single out a small set of restrictions such that the sets of admissible points in the selected set and in the original one are very close. This will allow us to replace The problem with another one with fewer restrictions, which will increase the speed of the algorithms used.
-Предлагается использовать методы машинного обучения для построения указанного множества наиболее важных ограничений.
+It is proposed to use machine learning methods to build the indicated set of the most important constraints.

-* '''Задача''': Стандартная постановка задач машинного обучения в контексте обучения без учителя (unsupervised learning) предполагает, что примеры (samples) независимы и получены из одного распределения вероятности. Однако зачастую наблюдаемые данные имеют динамическое происхождение и являются коррелироваными. Задача состоит в разработке эффективного метода для восстановления динамической графической модели (графа и параметров модели) по наблюдаемым коррелированным динамическим конфигурациям. Эта задача важна с теоретической точки зрения и имеет массу приложений. Основой алгоритма будет служить адаптация нового оптимального метода экранирования взаимодействий (interaction screening), разработанного для модели Изинга. Процесс решения будет сочетать в себе знакомство с теоретическими методами компьютерных наук / машинного обучения и численные эксперименты.
+* '''Problem:''' A standard machine learning problem statement in the context of unsupervised learning assumes that the examples are independent and come from the same probability distribution. However, often observed data are of dynamic origin and are correlated.

This The problem is theoretically important and has many applications. The basis of the algorithm will be the adaptation of a new optimal method of screening interactions (interaction screening), developed for the Ising model. The solution process will combine familiarity with computer science/machine learning theoretical methods and numerical experiments.

Задача сводится к разложению матрицы транзакционных данных «покупатели × продавцы» в произведение трёх неотрицательных матриц «покупатели × темы», «темы × темы», «темы × продавцы», при этом средняя матрица описывает направленный граф финансовых потоков в отрасли.

+* '''Problem:''' Credit scoring models are built step by step. In particular, a number of independent transformations of individual features are performed, and new features are generated. Each step uses its own quality criterion. It is required to build a scoring model that adequately describes the sample. Maximizing the quality of the model at each step does not guarantee the maximum quality of the resulting model. It is proposed to abandon the step-by-step construction of the scoring model. To do this, the quality criterion must include all the optimized parameters of the model.

+* '''Title:''' Estimated binding energy of protein and small molecules.
+* '''Problem:''' Modeling the binding of a protein and a small molecule (hereinafter referred to as a ligand) is based on the fact that the best ligand in its best position has the lowest free energy of interaction with the protein. It is necessary to estimate the free energy of protein and ligand binding. Complexes of proteins with ligands can be used for training, and for each protein there are several positions of the ligand: 1 correct, "native", for which the energy is minimal, and several generated incorrect ones. For a third of the data set, values are known that are proportional to the desired binding energy of ligands in native positions with the protein. There is a separate test set consisting of 1) complexes of proteins and ligands, for which it is necessary to find the best ligand position (the algorithm for obtaining ligand positions differs from that used in training), 2) complexes of proteins and ligands, for whose native positions it is necessary to predict the binding energy, and 3) proteins for which it is necessary to find the most strongly binding ligand.
+* '''Data:''' About 10000 complexes: for each of them there is 1 native pose and 18 (more can be generated) non-native ones. The main descriptors are histograms of distributions of distances between different atoms of the protein and ligand, the dimension of the vector of descriptors is ~ 20,000. The set of descriptors can be extended (you can generate poses with different deviations and use it as a descriptor, you can add the properties of small molecules: the number of bonds around which rotation is possible in a molecule, its surface area, its surface division by a Voronoi diagram. The data will be provided in the form of binary files with a python script to read.

+* '''Base algorithm:'''  We used a linear SVM (these are just lecture notes, I see no reason to give Vapnik here, especially since all this, including these lecture notes, is googled), the connection of which with an energy estimate that goes beyond scope of the classification The problem is described in the articles listed above. To take into account experimentally known values proportional to energy, it is proposed to use linear regression SVR .
+* '''Solution:''' It is necessary to reduce the previously used SVM problem to a regression problem and solve it using standard methods. To check the operation of the algorithm, both the test described above and several other test sets with similar The problems but different data will be used.
+* '''Novelty:''' Proper assessment of the quality of protein and ligand binding is used in drug development to find molecules that interact most strongly with the protein under study.
+Of particular importance is the assessment of the values of the binding energy of the protein with the ligand: the coefficient of correlation (Pearson) of the energy with its experimental values determined by different groups on the proposed test does not exceed 0.7. Prediction of the most strongly binding ligand from a large number of non-protein-binding molecules is also difficult. The aim of this work is to obtain a method that allows a fairly accurate assessment of protein binding to ligands. From the point of view of machine learning and optimization, it is of interest to combine classification and regression problems.
+* '''Appendix''' Given several data sets describing an atom in a molecule or a bond between atoms, with a small feature vector (usually 3-10 descriptors) and several classes corresponding to the atom's hybridization or bond order. The data itself can be from ~100 to 20,000 vectors depending on the type of atom. You need to test some kind of multiclass machine learning on this (random forests, neural network, something else), you can do anything with descriptors. We are currently using SVM. Not only the accuracy is important, but also the computational complexity of the prediction.

-* '''Задача''': Моделирование связывания белка и маленькой молекулы (далее -- лиганда) основывается на том, что наилучший лиганд в своем наилучшем положении имеет наименьшую свободную энергию взаимодействия с белком. Необходимо оценить свободную энергию связывания белка и лиганда. Для обучения могут использоваться комплексы белков с лигандами, причем для каждого белка есть несколько положений лиганда: 1 правильное, "нативное", для которых энергия минимальна, и несколько сгенерированных неправильных. Для трети набора данных известны значения, пропорциональные искомой энергии связывания лигандов в нативных положениях с белком. Есть отдельный тестовый сет, состоящий из 1) комплексов белков и лигандов, для которых нужно найти наилучшую позу лиганда (алгоритм получения положений лиганда отличается от используемого при обучении), 2) комплексов белков и лигандов, для нативных поз которых нужно предсказать энергию связывания, и 3) белков, для которых нужно найти наиболее сильно связывающийся лиганд.
+* '''Problem:''' Suppose that one needs to build a forecasting machine for a response variable. Given a large set of time series, one can advance a hypothesis that they are related to this variable. Relying upon this hypothesis, we can use given time series as features for the forecasting machine. However, the values of time series could be produced with different frequencies. Therefore, we should take into account not only the values, but the delays as well. The simplest model for forecast is a linear one. In the presence of large set of features this model can approximate the response quite well. To avoid the problem of multiscaling, we introduce a definition of delay-operators. Each delay-operator corresponds to one time series and represents continuous correlation function. This correlation function shows a dependence between the response variable and corresponding time series. Therefore, each delay-operator put weights on the values of corresponding time series depending on the greatness of the delay. Having these delay-operators, we avoid the problem of multiscaling. To find them, we use genetic programming and symbolic regression. If the resulted weighted linear regression model would produce poor approximation, we can use a nonlinear one instead. To find good nonlinear function, we would use symbolic regression as well.

-== Список проектов ==
+===1. 2016===
+* '''Data:''' Synergy of classification algorithms. Data from the UCI repository so that it can be compared directly with other works, in particular the work of Vapnik.
+* '''References:''' There are different approaches to combining SVMs: on example, bagging (http://www.ecse.rpiscrews.us/~cvrl/FaceProject/Homepage/Publication/ICPR04_final_cameraready_v4.pdf), also try and boosting (http://www.researchgate.net/profile/Hong-Mo_Je/publication/3974309_Pattern_classification_using_support_vector_machine_ensemble/links/09e415091bdc559051000000.pdf).
+* '''Base algorithm:'''  Described in the problem statement
+* '''Solution:''' a modification of the basic algorithm, or simply the Basic algorithm itself. The main thing is to compare with other methods and draw conclusions, in particular, about the relationship between the presence of an improvement in the quality and diversity of sets of reference objects built by different SVMs.
+* '''Novelty:''' It is known (for example, from Konstantin Vyacheslavovich's lectures) that it is not possible to build short compositions from strong classifiers (for example, SVM) using boosting (although they still try (see literature)). Therefore, it is proposed to build a nonlinear combination instead of a linear one. It is assumed that such a composition can give an increase in quality compared to a single SVM.
+* '''consultant''': Alexander Aduenko
-=== Задача 1 ===
+===2. 2016===
-* '''Данные''': Синергия алгоритмов классификации. Данные из репозитория UCI, чтобы можно было сравнивать напрямую с другими работами, в частности работами Вапника.
+* '''Title:''' Temporal theme model of the press release collection.
-* '''Литература''': существуют разные подходы к комбинированию SVM: например, bagging (http://www.ecse.rpiscrews.us/~cvrl/FaceProject/Homepage/Publication/ICPR04_final_cameraready_v4.pdf), также пробуют и boosting (http://www.researchgate.net/profile/Hong-Mo_Je/publication/3974309_Pattern_classification_using_support_vector_machine_ensemble/links/09e415091bdc559051000000.pdf).
+* '''Problem:''' Development of methods for analyzing the thematic structure of a large text collection and its dynamics over time. The problem is the assessment of the quality of the constructed structure. It is required to implement the criteria of stability and completeness of the temporal thematic model using manual selection of the found topics according to their interpretability, difference and eventfulness.
-* '''Базовой алгоритм''': Описан в постановке задачи
+* '''Data:''' A collection of press releases from the foreign ministries of a number of countries over 10 years, in English.
-* '''Решение''': модификация базового алгоритма, или просто сам базовый алгоритм. Главное - сравнить с другими методами и сделать выводы, в частности о связи наличия улучшения в качестве и разнообразия множеств опорных объектов, построенных разными SVM ами.
+* '''References:'''
-* '''Новизна''': известно (например, из лекций Константина Вячеславовича), что строить короткие композиции из сильных классификаторов (например, SVM) с помощью бустинга не получается (хотя все же пробуют (см. литературу)). Поэтому предлагается вместо линейной комбинации строить нелинейную. Предполагается, что такая композиция может дать прирост качества по сравнению с одиночным SVM.
+*# Doikov N.V. [[Media:2015_417_DoykovNV.pdf|Adaptive regularization of probabilistic topic models]]. VKR bachelor, VMK MSU. 2015.
-* '''Консультант''': Александр Адуенко
+* '''Base algorithm:'''  Blay's classic LDA with post-hoc time analysis.
+* '''Solution:''' Implementation of an additively regularized topic model using the [[BigARTM]] library. Building a series of thematic models. Evaluation of their interpretability, stability and completeness.
+* '''Novelty:''' Criteria for sustainability and completeness of thematic models are new.
+* '''consultant''': Nikita Doikov, '''problem author''' Vorontsov K. V.
-=== Задача 2 ===
+===3. 2016===
-* '''Название''': Темпоральная тематическая модель коллекции пресс-релизов.
+* '''Title:''' Coordination of logical and linear classification models in the information analysis of electrocardiosignals.
-* '''Задача''': Разработка методов анализа тематической структуры большой текстовой коллекции и её динамики во времени. Проблемой является оценка качества построенной структуры. Требуется реализовать критерии устойчивости и полноты темпоральной тематической модели с использованием ручного отбора найденных тем по их интерпретируемости, различности и событийности.
+* '''Problem:''' There are logical classifiers based on the identification of diagnostic standards for each disease and built by the Expert in semi-manual mode. For these classifiers, estimates of disease activities are determined, which have been used in the diagnostic system for many years and satisfy physician users. We build linear classifiers that are trained completely automatically and are ahead of logical classifiers in terms of classification quality. However, a direct transfer of the activity estimation technique to linear classifiers turned out to be impossible. It is required to build a linear activity model, setting it to reproduce the known activity estimates of the logical classifier.
-* '''Данные''':  Коллекция пресс-релизов внешнеполитических ведомств ряда стран за 10 лет, на английском языке.
+* '''Data:''' A selection of more than 10 thousand electrocardiograms with diagnoses for 32 diseases.
-* '''Литература''':
+* '''References:''' will issue :)

-* '''Решение''': Реализация аддитивно регуляризованной тематической модели с помощью библиотеки [[BigARTM]]. Построение серий тематических моделей. Оценивание их интерпретируемости, устойчивости и полноты.
+* '''Novelty:''' The problem of matching two models of different nature can be considered as learning with privileged information - a promising direction proposed by the machine learning classic VN Vapnik several years ago.

-=== Задача 3 ===
+===4. 2016===
-* '''Название''': Согласование логических и линейных моделей классификации в информационном анализе электрокардиосигналов.
+* '''Title:''' Thematic classification model for diagnosing diseases by electrocardiogram.
-* '''Задача''': Имеются логические классификаторы, основанные на выявлении диагностических эталонов для каждого заболевания и построенные экспертом в полуручном режиме. Для этих классификаторов определены оценки активностей заболеваний, которые уже много лет используются в диагностической системе и удовлетворяют пользователей-врачей. Мы строим линейные классификаторы, которые обучаются полностью автоматически и по качеству классификации опережают логические. Однако прямой перенос методики оценивания активности на линейные классификаторы оказался невозможен. Требуется построить линейную модель активности, настроив её на воспроизведение известных оценок активности логического классификатора.
+* '''Problem:''' [[Technology of information analysis of electrocardiosignals]] according to V.M.Uspensky is based on ECG conversion into a character string and selection of informative sets of words - diagnostic standards for each disease. The linear classifier builds one diagnostic standard for each disease. The Screenfax screening diagnostic system now uses four standards for each disease, built in a semi-manual mode. It is required to fully automate the process of constructing diagnostic standards and to determine their optimal number for each disease. To do this, it is supposed to finalize the thematic classification model of S. Tsyganova, to perform a new implementation under [[BigARTM]], to expand computational experiments, to improve the quality of classification.
-* '''Данные''': Выборка более 10 тысяч электрокардиограмм с диагнозами по 32 заболеваниям.
+* '''Data:''' A selection of more than 10 thousand electrocardiograms with diagnoses for 32 diseases.
-* '''Литература''': выдадим :)
+* '''References:''' will issue :)
-* '''Базовой алгоритм''': Линейный классификатор.
+* '''Base algorithm:'''  Classification models by V.Tselykh, thematic model by S.Tsyganova.
-* '''Решение''': Методы линейной регрессии, линейной классификации, отбора признаков.
+* '''Solution:''' Topic model implemented using the [[BigARTM]] library.
-* '''Новизна''': Задача согласования двух моделей различной природы может рассматриваться как обучение с привилегированной информацией (learning with privileged information) — перспективное направление, предложенное классиком машинного обучения В.Н.Вапником несколько лет назад.
+* '''Novelty:''' Topic models have not previously been used to classify sampled biomedical signals.
-* '''Консультант''': Влада Целых, '''автор задачи''' К.В.Воронцов.
+* '''consultant''': Svetlana Tsyganova, '''problem author''' Vorontsov K. V.
-=== Задача 4 ===
+===5. 2016===
-* '''Название''': Тематическая модель классификации для диагностики заболеваний по электрокардиограмме.
+* '''Title:''' Thematic models of distributive semantics for highlighting ethno-relevant topics in social networks.
-* '''Задача''': [[Технология информационного анализа электрокардиосигналов]] по В.М.Успенскому основана на преобразовании ЭКГ в символьную строку и выделении информативных наборов слов — диагностических эталонов каждого заболевания. Линейный классификатор строит один диагностический эталон для каждого заболевания. В системе скрининговой диагностики «Скринфакс» сейчас используется четыре эталона для каждого заболевания, построенных в полуручном режиме. Требуется полностью автоматизировать процесс построения диагностических эталонов и определять их оптимальное количество для каждого заболевания. Для этого предполагается доработать тематическую модель классификации С.Цыгановой, выполнить новую реализацию под [[BigARTM]], расширить вычислительные эксперименты, улучшить качество классификации.
+* '''Problem:''' Thematic modeling of social media text collections faces the problem of ultra-short documents. It is not always clear where to draw the boundaries between documents (possible options: a single post, a user's wall, all posts by a given user, all posts for a given day in a given region, and so on). Topic models give interpretable vector representations of words and documents, but their quality depends on the distribution of document lengths. The word2vec model is independent of document lengths, since it takes into account only the local contexts of words, but the coordinates of vector representations do not allow thematic interpretation. The objective of the project is to build a hybrid model that combines the advantages and is free from the disadvantages of both models.

Кроме того, в силу неоднородности данных (например, по регионам) предлагается строить смесь моделей, в которой каждая модель описывает свое подмножество выборки. При этом различным компонентам смеси могут соответствовать разные наборы признаков.

Предлагается использовать более интенсивные переборные стратегии, чтобы найти лучшие и более короткие диагностические наборы признаков.

The linear naive bayesian classifier with feature selection performs well in this The problem. However, only very simple greedy strategies have been used so far for feature selection. It is proposed to use more intensive enumeration strategies to find better and shorter diagnostic feature sets. However, the more intense the search, the higher the probability of overfitting. To reduce overfitting, it is proposed to use combinatorial estimates of overfitting of threshold decision rules. For efficient calculation of these estimates, it is proposed to use surrogate modeling.

Поэтому структурным описанием такой суперпозиции может являться ее DFS-code. Это строка, состоящая из меток вершин, записанных в порядке обхода дерева поиском в глубину. Зная арности соответствующих алгебраических функций, можем любой такой DFS-code восстановить за O(n) и получить обратно суперпозицию функций. На множестве подобных строковых описаний предлагается искать то строковое описание, которое будет соответствовать оптимальной модели.
+* '''Solution:''' The superposition of algebraic functions defines an ortree, on the vertices of which the labels of the corresponding algebraic functions or variables are given. Therefore, the structural description of such a superposition can be its DFS-code. This is a string consisting of vertex labels, written in the order in which the tree is traversed by depth-first search. Knowing the arities of the corresponding algebraic functions, we can restore any such DFS-code in O(n) and get back the superposition of functions. On the set of similar string descriptions, it is proposed to search for the string description that will correspond to the optimal model.

-* '''Название''': Тематическая модель классификации для диагностики заболеваний по электрокардиограмме.
+* '''Title:''' Stability of sampling of electrocardiosignals relative to frequency filtering.
-* '''Задача''': [[Технология информационного анализа электрокардиосигналов]] по В.М.Успенскому основана на преобразовании ЭКГ в символьную строку и выделении информативных наборов слов — диагностических эталонов каждого заболевания. Линейный классификатор строит один диагностический эталон для каждого заболевания. В системе скрининговой диагностики «Скринфакс» сейчас используется четыре эталона для каждого заболевания, построенных в полуручном режиме. Требуется полностью автоматизировать процесс построения диагностических эталонов и определять их оптимальное количество для каждого заболевания.

+* '''Problem:''' [[Technology of information analysis of electrocardiosignals]] according to V.M.Uspensky is based on the transformation of the electrocardiogram into a character string (codogram) and the selection of informative sets of words - diagnostic standards for each disease. The problem is that for discretization it is necessary to accurately determine the amplitude of the R-peaks. The amplitude can be affected by the frequency filtering of the signal, which is performed by the electrocardiograph at the hardware or software level. The problem is to evaluate how much different frequency filters (example, 50.4Hz mains suppression filter, high-pass filter) can affect the word frequencies in the codegram and the quality of the classification.

-=== Задача 5 ===
+==2015==
-* '''Название''': Тематические модели дистрибутивной семантики для выделения этнорелевантных тем в социальных сетях.
-* '''Задача''': Тематическое моделирование текстовых коллекций социальных медиа сталкивается с проблемой сверх-коротких документов. Не всегда ясно, где проводить границы между документами (возможные варианты: отдельный пост, стена пользователя, все сообщения данного пользователя, все сообщения за данный день в данном регионе, и т.д.). Тематические модели дают интерпретируемые векторные представления слов и документов, но их качество зависит от распределения длин документов. Модель word2vec независима от длин документов, так как учитывает лишь локальные контексты слов, но координаты векторных представлений не допускают тематическую интерпретацию. Задачей проекта является построение гибридной модели, объединяющей достоинства и свободной от недостатков обеих моделей.

В качестве уже имеющегося примера ответа на вопросы 1-3, смотри работы А. А. Варфоломеевой.
-* '''Данные''': Набор временных рядов, который подразумевает восстановление функциональных зависимостей. Предлагается сначала использовать синтетические данные или сразу применить алгоритм к прогнозированию временных рядов 1) потребления электроэнергии 2) физической активности с последующим анализом получающихся структур.

-* '''Базовой алгоритм''': Конкретно к предлагаемой проблеме базового алгоритма нет. Предлагается попробовать повторить эксперимент А. А. Варфоломеевой для другого структурного описания, чтобы понять, что происходит.
-* '''Решение''': Суперпозиция алгебраических функций задает ордерево, на вершинах которого заданы метки соответствующих алгебраических функций или переменных. Поэтому структурным описанием такой суперпозиции может являться ее DFS-code. Это строка, состоящая из меток вершин, записанных в порядке обхода дерева поиском в глубину. Зная арности соответствующих алгебраических функций, можем любой такой DFS-code восстановить за O(n) и получить обратно суперпозицию функций. На множестве подобных строковых описаний предлагается искать то строковое описание, которое будет соответствовать оптимальной модели.

-=== Задача 25 ===
-* '''Название''': Устойчивость дискретизации электрокардиосигналов относительно частотной фильтрации.
-* '''Задача''': [[Технология информационного анализа электрокардиосигналов]] по В.М.Успенскому основана на преобразовании электрокардиограммы в символьную строку (кодограмму) и выделении информативных наборов слов — диагностических эталонов каждого заболевания. Проблема в том, что для дискретизации необходимо достаточно точно определять амплитуду R-пиков. На амплитуду может влиять частотная фильтрация сигнала, которая производится электрокардиографом на аппаратном или программном уровне. Задача заключается в том, чтобы оценить, насколько сильно различные частотные фильтры (например, фильтр 50.4Гц, подавляющий воздействие электрической сети, высокочастотный фильтр) могут влиять на частоты слов в кодограмме и на качество классификации.
-* '''Данные''': электрокардиограммы в формате KDM.
-* '''Литература''': выдадим :)
-* '''Базовой алгоритм''': Линейный классификатор.
-* '''Решение''': Прямое и обратное преобразование Фурье, алгоритм детекции R-пиков на электрокардиограмме, алгоритм определения амплитуды R-пиков.
-* '''Новизна''': Исследование устойчивости кодограмм по отношению к частотной фильтрации с различными параметрами ранее не проводилось в информационном анализе электрокардиосигналов.
-* '''Консультант''': Виктор Сафронов (Научный центр им. В.И.Кулакова)
-=== Задача 26 ===
-* '''Название''': Построение отображений с минимальной деформацией для сравнения изображений с эталоном.
-* '''Задача''': Применить вариационный метод построения квазиизометрических отображений для решения классической задачи геометрической морфологии и регистрации изображений - построения двумерной или трехмерной деформации для сравнения с эталоном.
-* '''Данные''': Изображения в формате bmp. На первом этапе можно задавать простые тела посредством ч/б раскраски декартовой решетки.
-* '''Литература''':

-* '''Базовой алгоритм''': Использовать вариационный метод построения отображений, который ранее был предложен для построения пространственных отображений с заданным отображением границы [4], [5], в случае, когда  задается мера близости функций, описывающих геометрические тела, например, как среднеквадратичная мера близости функций яркости.
-* '''Решение''':  Для существующего кода, который реализует вариационный метод построения двумерных отображений с минимальным искажением, необходимо дописать модуль, реализующий добавку к функционалу, являющуюся мерой близости геометрических тел. Это включает вычисление самого функционала, его градиента, и поправки  к предобусловливателю.
-* '''Новизна''': Сравнить полученный метод с методом геодезического потока диффеоморфизмов, предложенного в работах Алэна Труве (см. ссылки [1]-[3]). Оценить качество приближения и быстродействие полученного алгоритма.
-* '''Консультант''': Владимир Анатольевич Гаранжа (ВЦ РАН).
-=== Задача 27 ===
-* '''Название''': Кросс-язычный тематический поиск научных публикаций.
-* '''Задача''': Содание прототипа поискового сервиса, который принимает в качестве запроса текст научной статьи на русском языке и выдаёт в качестве результата поиска тематически близкие статьи на английском языке из коллекции arXiv.org.
-* '''Данные''': Коллекция текстов arXiv.org, двуязычная коллекция текстов Википедии.
-* '''Литература''': выдадим.

-* '''Задача:'''
+Given:
-Дано:
+*# Time series of sales for several product groups in one hypermarket. Also, for each product, periods of shortage, periods of influence on the demand of calendar holidays and periods of holding are known. marketing promotions. A product classifier is also known: a tree of product groups, where the products themselves are leaves.
-*#	Временные ряды продаж  нескольких группам товаров в одном гипермаркете. Также для каждого товара известны периоды дефицита, периоды воздействия на спрос календарных праздников и периоды проведения. маркетинговых акций. Также известен товарный классификатор: дерево групп товаров, где сами товары являются листьями.
+*# Forecasting algorithm that is used to generate demand forecasts for these products: self-adaptive exponential smoothing (Trigg-Leach model, see [1])
-*#	Алгоритм прогнозирования, который используется для построения прогнозов спроса по этим товарам: самоадаптивное экспоненциальное сглаживание (модель Тригга-Лича, см. [1])
+*# Loss function by which the quality of forecasts is measured: MAPE.
-*#	Функция потерь, по которой измеряется качество прогнозов: MAPE.
+*# Requirements for building forecasts: forecasts must be built weekly for 4 weeks ahead (at the beginning of the current week, you need to build a forecast of total demand for the next week, a week in one, two, and 3).
-*#	Требования к построению прогнозов: прогнозы требуется строить понедельно на 4 недели вперёд (в начале текущей недели требуется построить прогноз суммарного спроса на следующую неделю, неделю через одну, через две, через 3).
-Гипотеза: спрос на отдельные товары слишком неустойчив, чтобы выявить характерную для них сезонность. Предлагается использовать данные о группах товаров, чтобы точнее определить параметры сезонности.
+Hypothesis: Demand for individual goods is too volatile to reveal their characteristic seasonality. It is proposed to use data on product groups in order to more accurately determine the parameters of seasonality.
-Замечание: возможны и другие варианты повышения качества прогнозирования за счёт работы с группами товаров.
+Note: there are other options for improving the quality of forecasting by working with groups of goods.
-Задача заключается в повышении качества прогнозирования в рамках поставленной задачи путём учёта эффекта взаимозаменяемости товаров, по сравнению с базовым алгоритмом.
+The problem is to improve the quality of forecasting within the framework of The problem by taking into account the effect of the interchangeability of goods, in comparison with the Basic algorithm
-Результат можно считать достигнутым, если показано статистически значимое повышение качества при построении серии прогнозов (не менее 20) по каждому временному ряду скользящим контролем.
+The result can be considered achieved if a statistically significant increase in quality is shown when building a series of forecasts (at least 20) for each time series using a sliding control.

-* '''Базовой алгоритм:''' Предлагется использовать модель сезонности [3] в сочетании с моделью Тригга-Лича в качестве алгоритма прогнозирования ряда без сезонности ([1] и [2]). При этом возможны 3 варианта алгоритма, в зависимости от способа оценки сезонности:
+* '''Base algorithm:'''  It is proposed to use the seasonality model [3] in combination with the Trigg-Leach model as a non-seasonal series prediction algorithm ([1] and [2]). In this case, 3 variants of the algorithm are possible, depending on the method of assessing seasonality:
-*# Сезонность оценивается по самому ряду продаж. Для товаров с "короткой" историей оценка сезонности не выполняется.
+*# Seasonality is estimated by the very series of sales. For products with a "short" history, seasonality is not assessed.
-*# Сезонность оценивается по группе товаров, исходя из классификатора товарных групп (нижний уровень классификатора)
+*# Seasonality is estimated for a group of goods, based on the classifier of commodity groups (lower level of the classifier)
-*# Сезонность оценивается по кластерам, исходя из методики [3], [4].
+*# Seasonality is estimated by clusters, based on the methodology [3], [4].
-* '''Решение:''' Требуется реализовать объединение модели сезонности [3] и модели Тригга-Лича в качестве алгоритма прогнозирования ряда без сезонности ([1] и [2]), с 3-мя вариантами анализа сезонности, описанными выше. При построение сезонных профилей необходимо исключать периоды маркетинговых акций (иначе может быть существенное искажение сезонности). Дальше понадобится серия экспериментов с анализом качества на реальных данных. При анализе качества можно исключать периоды проведения праздников и маркетинговых акций. По итогам экспериментов, возможно, потребуется адаптация алгоритма кластеризации.
+* '''Solution:''' It is required to implement the combination of the seasonality model [3] and the Trigg-Leach model as a non-seasonal series prediction algorithm ([1] and [2]), with the 3 variants of seasonality analysis described above. When constructing seasonal profiles, it is necessary to exclude periods of marketing campaigns (otherwise, there may be a significant distortion of seasonality). Next, you need a series of experiments with quality analysis on real data. When analyzing quality, you can exclude periods of holidays and marketing campaigns. Based on the results of the experiments, it may be necessary to adapt the clustering algorithm.
-* '''Новизна:''' Построение самоадаптивного алгоритма прогнозирования с учётом сезонности, выявляемой путём кластерного анализа.
+* '''Novelty:''' Building a self-adaptive forecasting algorithm taking into account seasonality, identified by cluster analysis.

+* '''Title:''' Checking the compliance of the electrocardiograph with the requirements of the diagnostic system "Screenfax" and assessing the quality of electrocardiograms.
+* '''Problem description:''' The problem of checking the compliance of an arbitrary electrocardiograph with the requirements of the "Screenfax" diagnostic system [1—4] is solved based on a comparison of electrocardiograms (ECG) of the same and the same patients recorded by both devices according to the ABAB scheme, where A is the first device, B - the second. The problem of automatic detection of low-quality electrocardiograms that do not meet the requirements of the diagnostic system is also solved.
+* '''Data:''' The selection consists of records with ECG values recorded by the device for which the test is being carried out, and by the device used in the Screenfax diagnostic system (data with a detailed description of the recording format will be provided to the person who selected The problem). You can use http://www.physionet.org/physiobank/database/ptbdb/ to test algorithms for R-peak detection and noise level estimation.

+* '''Solution:''' The problem of checking the compliance of an arbitrary electrocardiograph with the requirements of the "Screenfax" diagnostic system is proposed to be solved by constructing permutation statistical tests by comparing the values of RR-intervals and R-amplitudes and detected code sequences (calculated by amplitudes and intervals) for each diseases. This is where The problem of detecting R peaks comes in. In The problem of detecting low-quality electrocardiograms, The problem of estimating the noise level arises. In addition, it is necessary to learn how to filter out ECG with non-informative amplitude values or a large spread of interval values, since the method of analyzing electrocardiographic signals is not applicable to the diagnosis of arrhythmia.

+* '''Title:''' Simplification of the IR models structure
+* '''Problem:''' To achieve the acceptable quality of the information retrieval models, modern search engines use models of very complex structure. In current research we propose to simplify the model structure and make it interpretable without decreasing the model accuracy. To do this, we follow the idea from (Goswami et al., 2014) of constructing the set of nonlinear IR functions of simple structure and admissible accuracy. However, each of these functions is expected to have lower accuracy while comparing with the best IR model of complex structure. Thus, we propose to approximate this complex model with the linear combination of simple nonlinear functions and expect to obtain the comparable quality of solution.

+* '''Title:''' Testing non-parametric time series forecasting algorithms under non-stationary conditions
+* '''Problem:''' One of the key assumptions about the distribution of data in non-parametric is the assumption that the time series is stationary. The adequacy of forecasts if this requirement is not met is not guaranteed. It is required to develop a method for determining the fulfillment of the condition of local stationarity of the time series to study the applicability of the main algorithms of nonparametric forecasting in the absence of stationarity. Consider the main methods of nonparametric regression, such as kernel smoothing, spline smoothing, autoregression, moving average, etc.

+* '''Title:''' Regularization of the linear naive bayes classifier.
+* '''Problem:''' Building a linear classifier is one of the classic and most well studied machine learning The problems. A linear naive bayesian (LNB) classifier has the strong advantage that it builds in time that is linear in sample length, and the strong limitation that it assumes that the features are independent in its derivation. On some data, LNB performs surprisingly well, despite a clear violation of the feature independence hypothesis. The Linear Support Vector Machine (SVM) is considered to be a very successful method, but takes a long time on large samples. Both of these methods work in the same space of linear classifiers. The idea of the study is to bring LNB closer to SVM in terms of quality, but without loss of efficiency, by means of minor corrections.
+* '''Data:''' One of the three data sets, optional: classification of texts into scientific and non-scientific, classification of abstracts by fields of science, classification of ECG codograms for sick and healthy.

To start learning words, you need to type at least 10 words. It is required to build a probabilistic word generation model that adapts to the interests of the user.

+* '''Base algorithm:'''  Random word selection algorithm.
+* '''Solution:''' The topic model for each user determines the topic profile of his interests p(t|u). To generate words, word distributions from the distributions p(w|t) of the topics of the given user are used. Dependences of the quality functionals of the thematic model on the iteration number are constructed. The main functionality of quality is the ability of the model to predict which words the user will leave and which ones they will discard.

+*  Differential diagnosis of diseases by electrocardiogram
+* '''Problem:''' It is proposed to solve a typical classification problem. Signs are 216 characteristics calculated from the electrocardiogram. It is necessary to evaluate the quality of the classification on a delayed control sample. To do this, the fractions of errors of the first and second kind are calculated. Under the error of the first kind is meant the assignment of healthy people to the class of patients, the second kind - the assignment of patients to the class of healthy people. Preference is given to minimizing Type II errors.
+* '''Data:''' For each of the 5 diseases, there are 2 types of samples. Reference - more reliable, specially selected cases. The rest are cases when the diagnoses were established by doctors less reliably; these samples are proposed to be used for control.

+* '''consultant:''' A. P. Motrenko
+* '''Problem:''' To improve the quality of the time series forecast, I would like to use expert statements about the presence of a causal relationship between events. To do this, it is necessary to be able to assess the reliability of expert statements. It is impossible to prove the existence of a causal relationship by statistical methods. The researcher can only check the presence of a certain structure of communication. The purpose of The problem is, based on expert statements about the presence of a connection between events, to examine the time series for the presence of various structural connections and find the structure that is most consistent with the Expert's opinion.

+* '''Problem:''' The problem of credit scoring is to determine the level of creditworthiness of the borrower who applied for a loan. To do this, a borrower's questionnaire is used, containing both numerical data (age, income, time of residence in the country) and categorical features (gender, profession). It is required, having historical information on loan repayments by other borrowers, to determine whether the client in question will return the loan. Thus, it is required to solve the problem of classification. Since the data can be heterogeneous (for example, if there are different income regions in the country), the data can be described not by one, but by several models. In this paper, we propose to compare two methods for constructing multimodels: mixtures of logistic models and gradient boosting.

+* Search algorithms for the most informative objects and features in logistic regression
+* Logistic regression is a statistical model that is used to predict the probability of an event occurring based on the values of a set of features. It has applications, for example, in medicine [http://math.tntech.edu/machida/MSD/lecture7.pdf] and credit scrolling. In real conditions, the number of features is usually large, and the most important The problem is to select only essential features, as well as to search for objects that are atypical for one reason or another.
+* Keywords: logit model, feature selection, boosting.
+===2===
+* Using the method of principal components in the construction of integral indicators
+* This paper considers Using the method of principal components in the construction of integral indicators. The results obtained are compared with the results given by the Pareto stratification method. An integral indicator is being built for Russian universities. For this, biographies of the 30 richest businessmen in Russia according to the Forbes magazine for 2011 are used.
+* ''Keywords:'' integral indicator, expert estimates, parameter weights, principal component method, Pareto stratification method.
+===3===
+* Approximation of empirical distribution functions
+* The work is devoted to methods of approximation of functions for efficient calculation of integrals. Practical The problems usually have data at certain points in time or space. When making assumptions about the remaining points, it becomes necessary to approximate the distribution function of the quantity under study, as well as to estimate the corresponding error. For its calculation, it is possible to use methods of different accuracy.
+* Keywords: Monte Carlo method, calculation of distribution functions, empirical distribution functions.
+===4===
+* Local prediction methods with choice of transformation
+* Time series forecasting problems have many applications in various fields such as economics, physics, and medicine. Their solution is a forecast for the near future based on the already known values of the predicted series at previous points in time. In the work, a local forecasting algorithm will be built taking into account transformations, which allows, without human intervention, to identify visually similar sections of the time series.

+* Non-parametric forecasting: kernel selection, parameter tuning
+* The paper describes the method of nuclear smoothing of the time series, as one of the types of nonparametric regression. The essence of the method
+consists in restoring the function of time as a weighted linear combination of points from some neighborhood. A continuous bounded symmetric real weight function is called a kernel. The resulting kernel estimate is used to predict the next point in the series. The dependence of the quality of prediction on the parameters of the kernel and the superimposed noise is investigated.
+===2. 2011===
+* Exponential Smoothing and Prediction
+* The paper investigates the application of the exponential smoothing algorithm to time series forecasting. The algorithm is based on taking into account the previous values of the series with weights decreasing as you move away from the studied section of the time series. The behavior of the algorithm on model data in various models of weights is studied. An analysis of the operation of the algorithm on real data - stock indices was carried out.

-* '''Название''': Simplification of the IR models structure
+*  Prediction by Discrete Argument Functions
-* '''Задача''':  To achieve the acceptable quality of the information retrieval models, modern search engines use models of very complex structure. In current research we propose to simplify the model structure and make it interpretable without decreasing the model accuracy. To do this, we follow the idea from (Goswami et al., 2014) of constructing the set of nonlinear IR functions of simple structure and admissible accuracy. However, each of this functions is expected to have lower accuracy while comparing with the best IR model of complex structure. Thus, we propose to approximate this complex model with the linear combination of simple nonlinear functions and expect to obtain the comparable quality of solution.

-* '''Название''': Тестирование непараметрических алгоритмов прогнозирования временных рядов в условиях нестационарности
+* Local forecasting methods, search for metrics
-* '''Задача''': Одним из ключевых предположений о распределении данных при непараметрическом является предположение о стационарности временного ряда. Адекватность прогнозов при невыполнении этого требования не гарантируется. Требуется разработать метод определения выполнения условия локальной стационарности временного ряда исследовать применимость основных алгоритмов непараметрического прогнозирования в отсутствии стационарности. Рассмотреть основные методы непараметрической регрессии, такие как ядерное сглаживание, сглаживание сплайнами, авторегрессия, скользящее среднее и др.
+* The time series is divided into separate sections, each of which is associated with a point in the n-dimensional feature space. The local model is calculated in three successive stages. The first one finds the k-nearest neighbors of the observed point. The second one builds a simple model using only these k neighbors. The third - using this model, predicts the next one based on the observed point. Many researchers use the Euclidean metric to measure distances between points. This work is intended to compare the accuracy of forecasting when using different metrics. In particular, it is required to investigate the optimal set of weights in the weighted metric to maximize the prediction accuracy.

+prehistory, i.e. in a series you need to find the part that after some transformation of A becomes similar to the part we are trying to predict. Finding such a transformation A and is the goal of this project. To determine the degree of similarity, the function B is used - the function of the proximity of two segments time series. This is how we find the closest neighbor to our backstory. In general, we are looking for several nearest neighbors. The continuation will be written as their linear combination.

-* '''Название''': Построение иерархической тематической модели крупной конференции
+*  Time Series Flattening: Forecasting with DTW
-* '''Задача''': Ежегодно, программный комитет крупной конференции EURO (более 2000 докладов) сталкивается с задачей построения иерархической модели тезисов конференции. В силу того, что структура конференции слабо меняется из года в год, предлагается построить тематическую модель будущей конференции, используя экспертные модели конференций прошлых лет. При этом возникают следующие подзадачи:
+* Time series is a sequence of time-ordered values of some real variable <tex>$\mathbf{x}=\{x_{t}\}_{t=1}^T\in\mathbb{R }^T$</tex>. The problem that accompanies the appearance of time series is the comparison of one data sequence with another. Comparison of sequences is greatly simplified after the deformation of the time series along one of the axes and its alignment. Dynamic time warping (DTW) is a technique for effectively leveling time series. DTW methods are used in speech recognition, information analysis in robotics, industry, medicine and other areas.
-# Классификация тезисов новой конференции.
+* The purpose of the work is to give an example of alignment, to introduce a comparison functional for two time series, which has the natural properties of commutativity, reflexivity and transitivity. The functional should take two time series as input, and at the output give a number characterizing the degree of their "similarity".

+*  Investigation of Convergence in Prediction by Neural Networks with Feedback
+* The dependence of the convergence rate in time series forecasting on the parameters of a neural network with feedback is investigated. The concept of feedback is typical for dynamic systems in which the output signal of some element of the system affects the input signal of this element. The output signal can be represented as an infinite weighted the sum of the current and previous input signals. The Jordan network is used as a neural network model. It is proposed to investigate the rate of convergence depending on the choice of the activation function (sigmoid, hyperbolic tangent), on the number of neurons in the intermediate layer and on the width of the sliding window. We also explore a way to increase the rate of convergence using the generalized delta rule.

-* '''Название''': Регуляризация линейного наивного байесовского классификатора.
+*  Multidimensional caterpillar, choice of length and number of caterpillar components
-* '''Задача''': Построение линейного классификатора является одной из классических и самых хорошо изученных задач машинного обучения. Линейный наивный байесовский (LNB) классификатор имеет сильное преимущество — он строится за время, линейное по длине выборки, и сильное ограничение — при его выводе предполагается, что признаки независимы. На некоторых данных LNB работает удивительно хорошо, несмотря на явное нарушение гипотезы о независимости признаков. Линейная машина опорных векторов (SVM) считается очень успешным методом, но на больших выборках работает долго. Оба эти метода работают в одном и том же пространстве линейных классификаторов. Идея исследования состоит в том, чтобы путём незначительных поправок LNB приблизить его к SVM по качеству, но без утраты эффективности.
+* The work is devoted to the study of one of the methods for analyzing multivariate time series - the "caterpillar" method, also known as Singular Spectrum Analysis or SSA. The method can be divided into four stages - the representation of the time series in the form of a matrix using a shift procedure, the calculation of the covariance matrix of the sample and its singular value decomposition, the selection of principal components related to various components of the series (from slowly changing and periodic to noise), and, finally, line restoration.

+*  Using the Granger Test in Time Series Forecasting
-* '''Задача''': Мобильное приложение для изучения английских слов предлагает пользователю слова одно за другим. Пользователь может либо добавить слово к изучаемым, либо откинуть. Чтобы начать учить слова, нужно набрать, как минимум, 10 слов. Требуется построить вероятностную модель генерации слов, адаптирующуюся под интересы пользователя.
+* When predicting a series, it can be useful to determine whether a given series is "dependent" on some other series. The Granger test, based on statistical tests, helps to identify such a relationship (in this case, the method does not guarantee an accurate result - when comparing two rows that depend on another row, an error is possible). The method is used in forecasting economic and natural phenomena (for example, earthquakes).
-* '''Данные''':  Для каждого пользователя имеются списки добавленных и откинутых слов. Кроме того, предполагается использовать большую внешнюю коллекцию текстов, например, Википедию, для устойчивого определения тематики.
