Люди уже придумали все необходимое. Когда-то давно человечество развивалось очень бурно – постоянно менялись не только вещи, окружавшие людей, но и слова, которыми они пользовались. В те дни было много разных названий для творческого человека - инженер, поэт, ученый. И все они постоянно изобретали новое. Но это было детство человечества. А потом оно достигло зрелости. Творчество не исчезло - но оно стало сводиться к выбору из уже созданного. Говоря образно, мы больше не выращиваем виноград. Мы посылаем за бутылкой в погреб. Людей, которые занимаются этим, называют "сомелье". (В. Пелевин)

The chat-link

The statistical analysis of spatial time series requires additional methods of data analysis. First, we suppose time is continuous, put to the state space changes \(\frac{d\mathbf{x}}{dt}\) and use neural ordinary and stochastic differential equations. Second, we analyze a multivariate and multidimensional time series and use the tensor representation and tensor analysis. Third, since the time series have significant cross-correlation we model them in the Riemannian space. Fourth, medical time series are periodic, the base model is the pendulum model, \(\frac{d^2x}{dt^2}=-c\sin{x}\). We use physics-informed neural networks to approximate data. Fifth, the practical experiments involve multiple data sources. We use canonical correlation analysis with latent state space. This space aligns the source and target spaces and generates data in source and target manifolds.

Applications

This field of Machine Learning applies to any field where the measurements have continuous time and space data acquired from multimodal sources: climate modeling, neural interfaces, solid-state physics, electronics, fluid dynamics, and many more. We will carefully collect both the theory and its practice.

Course arrangement

Your profit

Your goal is to enhance your abilities to convey messages to the reader in the language of applied mathematics. The main part of your MS thesis work is the theoretical foundations of Machine Learning, where you present your personal results supported by the necessary theory.

Structure of a seminar

The semester lasts 10 weeks, and five couple of weeks for homework.

  • Odd week: introduction to the topic and handout of a theme for the homework.
  • Even week: a discussion of the essay, collecting the list of improvements to each essay.
  • Odd week: a discussion of the improved essay, putting the essays into a joint structure.

Scoring

Each essay brings one point, and each improvement brings one point. If an easy is perfect, no improvement is required, it counts as one plus one point. The threshold for binary decision is seven points.

The homework

The course gives two credits, so it requires time. The result is a two-page essay. It delivers an introduction to the designated topic. It could be automatically generated or collected from Wikipedia. The main requirement is that you be responsible for each statement of your essay. Each formula is yours.

The essay carries a comprehensive and strict answer to the topic question, illustrative plots are welcome. The result is ready to compile in a joint manuscript after the Even week. So please use the LaTeX template.

The style is the set theory, algebra, analysis, and Bayesian statistics. Category theory and homotopy theory are welcome.

This course gives you two credits, so it is 76/10 = 5 hours of weekly homework.

Templated and links

  • The course Git Hub to download the homework essays
  • The overleaf to compile the joint manuscript
  • The LaTeX template for an essay
  • The course chat to ask questions

Requirements for the text and the discussion

  1. Comprehensive explanation of the method or the question we discuss
  2. Only the principle, no experiments
  3. Two-page text (more or less)
  4. The reader is a second or third-year student
  5. The picture is obligatory
  6. However, a brief reference to some deep learning structure is welcome
  7. Talk could be a slide or a text itself
  8. The list of references with doi
  9. Tell how it was generated
  10. Observing a gap, put a note about it (to question later)

Style remarks for the essays

Automatic generation of mediocre-quality texts increased requirements for the quality of the new messages. It makes novelty rare and makes the authorship appreciated. But it simplifies the ways of delivering. So since textbook generation has become simple, we will use generative chats to train our skills of reader persuasion. The reader is our MS-thesis defense committee.

Additional remarks for clarification. Люди уже придумали все необходимое. Когда-то давно человечество развивалось очень бурно – постоянно менялись не только вещи, окружавшие людей, но и слова, которыми они пользовались. В те дни было много разных названий для творческого человека – инженер, поэт, ученый. И все они постоянно изобретали новое. Но это было детство человечества. А потом оно достигло зрелости. Творчество не исчезло - но оно стало сводиться к выбору из уже созданного. Говоря образно, мы больше не выращиваем виноград. Мы посылаем за бутылкой в погреб. Людей, которые занимаются этим, называют "сомелье". (В. Пелевин)

Avoid this style (reserved for the seminar)

  1. CCA comprehensive overwiev
  2. PCA tutorial

Table of homeworks

These ten weeks we discuss the next five topics:

  1. Multimodal data
  2. Continous time and space models
  3. Physics-informed models

  1. deterministic model,
  2. generative model,
  3. stochastic-deterministic decomposition method.

See the questions below for your reference.

Multimodal data

First series

  1. Canonical Correlation Analysis
  2. CCA in tensor representation
  3. Kernel CCA in Hilbert and L2[a,b] spaces
  4. CCA versus Cross-Attention Transformers
  5. Generative CCA, diffusion, and flow
  6. Comparative analysis of variants of CCA like PLS and others
  7. Functional PCA

Continous models

Second series

  1. Neural ODE
  2. Continous state space models
  3. Continous normalizing flows
  4. Ajoint method and continuous backpropagation
  5. Neural Delayed Differential Equations

  5. Persistent homology and dimensionality reduction (say, arXiv:2302.03447 with embedding delays)

Generative and Riemannian models

Fifth series

  1. Genertive Riemannian models. How do we extract and use the distribution?
  2. Gererative Canonical Correlation Analysis and its connection with the Riemannian spaces in the latent part
  3. Scoring-based Riemannian models. How do we extract and use the distribution?
  4. Generative convolutional models for tensors. Is there a continuous-time? (A variant is the Riemannian Residual Networks).
  5. Riemannian continuous normalizing flows. How do we generate a time series of a given distribution?
