+ | * '''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. | ||

+ | * '''Title:''' Knowledge distillation in deep networks and alignment of model structures | ||

+ | * '''Problem description:''' It is required to build a network of the simplest structure, a student model, using a high quality teacher model. Show how the student's accuracy and stability change. The result of the experiment is a graph complexity-accuracy-stability, where each model is accurate. | ||

+ | * '''Data:''' CIFAR-10. It is assumed that the teacher has a structure open for analysis with a large number of layers. | ||

+ | * '''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.

- | + | * '''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. | |

This allows us to consider time series as continuous in time. | ||

- | + | * '''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 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. | ||

+ | * '''Problem description:''' There is the same problem as Representation learning. One of the most popular approaches to solving this problem is contrastive learning. At the same time, in the data we learn from, there are often markup errors: false positive/false negative. It is proposed to analyze various ways to eliminate these biases caused by errors.

+ | * '''Problem description:''' The most popular generative model today is the diffusion model. Its main disadvantage is the speed of sampling. To sample 1 picture, you need to run 1 neural network 100-1000 times. There are ways to speed up this process. One such way is to use adversarial networks. It is proposed to develop this method and explore various ways to set the functional for sampling | ||

+ | ===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 | ||

+ | * '''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. | ||

+ | * '''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. | ||

To solve the problem, it is proposed to build a ranking model based on gradient boosting. As signs, you can use the year of publication, the citation of the article, the citation of its authors, the semantic proximity of the publication to the review, to its local context, etc. | ||

+ | * '''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 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. | ||

+ | * '''Problem description:''' The idea of self-supervised learning is to solve an artificially selected The problem to get useful representations of data without markup. One of the most popular approaches is the use of contrastive learning, during which the model is trained to minimize the distance between representations of augmented copies of the same object. The purpose of The problem is to investigate the quality of the resulting representations depending on the choice of the proximity measure (similarity measure) used in training, and to offer our own version of distance measurement | ||

+ | * '''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. | ||

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. | ||

This allows us to consider time series as continuous in time. | ||

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 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]. | ||

+ | * '''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. | ||

+ | * '''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. | ||

+ | ===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. | ||

+ | * '''References:''' The proposed algorithms are based on 3 articles: | ||

+ | * '''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:''' 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). | ||

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. | ||

+ | * '''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. | ||

+ | * '''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. | ||

+ | * '''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.

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.

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.

+ | *'''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. | ||

+ | * '''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).<br />You can suggest some modification, for example, the distance between the hidden layers of the autoencoder for points i and j. | ||

+ | * '''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.<br />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.<br />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. | ||

+ | * '''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).<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. | ||

+ | * '''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. | ||

Therefore, the existing operations of convolutions on graphs are greatly simplified or do not generalize to different topologies.

+ | *'''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. | ||

+ | * '''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. | ||

+ | *'''Name:''' Analysis of the properties of an ensemble of locally approximating models. | ||

+ | *'''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. | ||

+ | *'''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. | ||

+ | *'''Data:''' | ||

+ | *# Synthetically generated data. | ||

+ | * '''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. | ||

+ | * '''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. | ||

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. | ||

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.

+ | * '''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. | ||

+ | * '''Title:''' Deep Learning for reliable detection of tandem repeats in 3D protein structures [[Media:Strijov_3D_CNN.pdf|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). | ||

+ | * '''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] [https://www.tensorflow.org/] | ||

+ | * '''Solution:''' 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. | ||

+ | * '''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:''' 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. | ||

+ | * '''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:''' 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. | ||

+ | *'''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. | ||

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

+ | * '''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 [https://www.overleaf.com/read/rjdnyyxpdkyj] | ||

+ | * '''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:''' | ||

+ | *# 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. | ||

+ | *# Data for regression. For each of the presented complexes, the value of the quantity is known, which can be interpreted as the binding energy. | ||

+ | *# [https://alex.smola.org/papers/2003/SmoSch03b.pdf] (section 1) | ||

+ | * '''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. | ||

+ | * '''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. | ||

+ | * '''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. | ||

+ | * '''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.

+ | * '''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. | ||

+ | * '''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). | ||

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:''' Deep Learning for reliable detection of tandem repeats in 3D protein structures [[Media:Strijov_3D_CNN.pdf|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). | ||

+ | * '''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/] | ||

+ | * '''Solution:''' 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. | ||

+ | * '''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. | ||

+ | * '''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. | ||

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. | ||

+ | * '''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. | ||

+ | * '''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. | ||

+ | * '''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. | ||

+ | * '''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. | ||

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:''' 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: | ||

+ | *# atom type (graph vertex type, about 150 classes), | ||

+ | *# atom hybridization (auxiliary feature, vertex type, 4 classes), | ||

+ | *# 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. | ||

+ | 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. | ||

+ | * '''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:''' | ||

+ | *# 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. | ||

+ | *# Data for regression. | ||

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

+ | * '''Base 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, 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. | ||

+ | * '''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. | ||

+ | * '''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. | ||

+ | * '''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.

The basis of the algorithm will be the adaptation of a new optimal method of screening interactions (interaction screening), developed for the Ising model.

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:''' 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. | ||

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. | ||

+ | * '''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:''' 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. | ||

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. | ||

+ | * '''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. | ||

+ | * '''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. | ||
