Physics-informed machine learning

(seminars by Andriy Graboviy and Vadim Strijov)


The course consists of a series of group discussions devoted to various aspects of data modelling in continuous spaces. It will reduce the gap between the models of theoretical physics and the noisy measurements, performed under complex experimental circumstances. To show the selected neural network is an adequate parametrisation of the modelled phenomenon, we use geometrical axiomatic approach. We discuss the role of manifolds, tensors and differential forms in the neural network-based model selection.

The basics for the course are the book Geometric Deep Learning: April 2021 by Michael Bronstein et al. and the paper Physics-informed machine learning // Nature: May 2021 by George Em Karniadakis et al.

Structure of the talk

The talk is based on two-page essay ([template]).

  1. Field and goals of a method or a model
  2. An overview of the method
  3. Notable authors and references
  4. Rigorous description, the theoretical part
  5. Algorithm and link to the code
  6. Application with plots


Each student presents two talks. Each talk lasts 25 minutes and concludes with a five-minute written test (discussion is better). A seminar presentation gives 1 point, a formatted seminar text gives 1 point, a test gives 1 point, a reasonable test response gives 0.1 point. Bonus 1 point for a great talk. Highly recommended to present list of references 1 week before (for 1 point bonus reward, of course).
