HSE Scientists Train Neural Network to 'Hear' Faults in Electric Motors
Researchers at the AI and Digital Science Institute of the HSE Faculty of Computer Science have developed a new method—the Signature-Guided Data Augmentation (SGDA) framework—that achieves 99% accuracy in motor fault detection and 86% accuracy in fault classification. The application of this approach can reduce industrial equipment repair costs, minimise downtime, and improve production safety. The study results have been published in Engineering Applications of Artificial Intelligence.

'The Humanities Serve as a Conscience'
Maria Mizernaia studies Soviet literature and the history of book publishing. In this interview for the HSE Young Scientists project, she discusses plans to publish a novel about besieged Leningrad, AI-provoked reflections on what it means to be human, and how novels can help satisfy our dopamine hunger.

Is It Possible to Predict a Citys Life Based on the Shape of Its Neighbourhoods?
Is it possible to predict, based on the configuration of streets and buildings, where a café will open or where traffic congestion will occur? Participants in the Spatial Analysis and Modelling of Urban Processes research and study group use open data and machine learning to identify universal patterns. Alexander Sheludkov and Eduard Somov discuss the purpose of comparing cities, the need for new forms of urban statistics, and how open data is transforming approaches to urban studies.

Diffusion processes on the Thoma cone

Functional Analysis and Its Applications. 2016. Vol. 50. No. 3. P. 237–240.
Olshanski G.

The Thoma cone is a certain infinite-dimensional space that arises in the representation theory of the infinite symmetric group. The present note is a continuation of a paper by A. M. Borodin and the author (Electr. J. Probab. 18 (2013), no. 75), where a 2-parameter family of continuous-time Markov processes on the Thoma cone was constructed. The purpose of the note is to show that these processes are diffusions.

Denote by S(\infty) the infinite symmetric group formed by finitary permutations of the set of natural numbers; this is a countable group. We define its virtual group algebra; it is a completion of the standard group algebra  С[S(\infty)]. The virtual group algebra is obtained from the finite-dimensional group algebras C[S(n)] as the result of a ...

Subword complexes were defined by A.Knutson and E.Miller in 2004 for describing Gröbner degenerations of matrix Schubert varieties. The facets of such a complex are indexed by pipe dreams, or, equivalently, by the monomials in the corresponding Schubert polynomial. In 2017 S.Assaf and D.Searles defined a basis of slide polynomials, generalizing Stanley symmetric functions, and ...

Elements of the q-Askey Scheme in the Algebra of Symmetric Functions
Olshanski G., Cuenca C., Moscow Mathematical Journal 2020 Vol. 20 No. 4 P. 645–694
The classical q-hypergeometric orthogonal polynomials are assembled into a hierarchy called the q-Askey scheme. At the top of the hierarchy, there are two closely related families, the Askey–Wilson and q -Racah polynomials. As it is well known, their construction admits a generalization leading to remarkable orthogonal symmetric polynomials in several variables. We construct an analogue of the ...

Топологический носитель z-мер на симплексе Тома
Olshanski G., Функциональный анализ и его приложения 2018 Т. 52 № 4 С. 86–88
The Thoma simplex Ω is an infinite-dimensional space, a kind of dual object to the infinite symmetric group. The z-measures are probability measures on Ω depending on three continuous parameters. One of them is the parameter of the Jack symmetric functions, and in the limit as it goes to 0, the z-measures turn into the ...

Interpolation Macdonald polynomials and Cauchy-type identities
Olshanski G., Journal of Combinatorial Theory, Series A 2019 Vol. 162 P. 65–117
Let Sym denote the algebra of symmetric functions and P_μ( · ; q, t) and Q_μ( · ; q, t) be the Macdonald symmetric functions (recall that they differ by scalar factors only). The (q, t)-Cauchy identity expresses the fact that the P_μ( · ; q, t)’s form an orthogonal basis in Sym with respect to ...

Stochastic Processes
Бородин А. Н., Switzerland: Birkhauser/Springer, 2017.
This book provides a rigorous yet accessible introduction to the theory of stochastic processes. A significant part of the book is devoted to the classic theory of stochastic processes. In turn, it also presents proofs of well-known results, sometimes together with new approaches. Moreover, the book explores topics not previously covered elsewhere, such as distributions of ...

On Poisson equations with a potential in the whole space for ``ergodic" generators
Veretennikov A., Теорiя Ймовiрностей та Математична Статистика 2016 Vol. 95 P. 178–188
Poisson equation in the whole space was studied earlier for so called ergodic generators L corresponding to homogeneous Markov diffusions. Solving this equation is one of the main tools for diffusion approximation in the theory of stochastic averaging and homogenisation. Here a similar equation with a potential is considered, firstly because it is natural for ...

Nonlinear Trend Exclusion Procedure for Models defined by Stochastic Differential and Difference Equations
Konakov V., Markova A., Automation and Remote Control 2017 Vol. 78 No. 8 P. 1438–1448
We consider the diffusion process and its approximation by Markov chain with nonlinear unbounded trends. The usual parametrix method is not applicable because these models have unbounded trends. We describe a procedure that allows to exclude nonlinear unbounded trend and move to stochastic differential equation with bounded drift and diffusion coefficients. A similar procedure is ...

Stability of Densities for Perturbed Diffusions and Markov Chains
Konakov V., Kozhina A., Menozzi S., ESAIM: Probability and Statistics 2017 Vol. 21 P. 88–112
We study the sensitivity of the densities of non degenerate diffusion processes and related Markov Chains with respect to a perturbation of the coefficients. Natural applications of these results appear in models with misspecified coefficients or for the investigation of the weak error of the Euler scheme with irregular coefficients. ...

Доказано, что сложность реализации произвольной симметрической булевой функции f от n переменных для f не равной тождественно единице при реализации схемами в базисе антицепных функций, т.е. функций, принимающих значение 1 лишь на попарно несравнимых наборах, равна min(k(f),n-k(f)+2), где k(f) - количество слоев, на которых функция f равна 1. ...
