Polina Tabakova decided to apply for a Philology degree at HSE in Nizhny Novgorod because she grew up in Mari El and did not want to move far away from the Russian forests. In an interview for the Young Scientists of HSE University project, she spoke about the genre of the campus novel, the existential drama of Kolobok, and a blackout version of Eugene Onegin.
Researchers from the AI and Digital Science Institute at the HSE Faculty of Computer Science have developed a new compression method for large language models such as GPT and LLaMA that reduces their size by 25–36% without additional training or significant loss of accuracy. This is the first approach to use mathematical transformations—specifically, rotations of model weights—to make models more amenable to compression with structured matrices. The study results have been published in ACL Findings 2025. The code is available on GitHub.

The main results of the work are new Bayes–Nash equilibria related to the theory of oli gopoly. The article is divided into two parts. The first part considers the classical problem of price competition with product differentiation. (That is, each firm produces one product, but the pro ducts differ. This is the next most complex ...
Coopetition means that in economic interactions, both competition and cooperation are
presented in the same time. We built and investigated analytically and numerically game theoretic
models of coopetition in normal form and in the form of characteristic function. The basic model
in normal form reflects competition between firms in Cournot oligopoly and their cooperation in
mutually profitable activities such ...

In this paper, we build and investigate cooperative games with different characteristic
functions (von Neumann–Morgenstern, Petrosyan–Zaccour, Gromova–Petrosyan) on the
base of symmetrical Cournot oligopoly game-theoretic models in normal form. We find
Nash and Stackelberg equilibria and cooperative solutions for nonsymmetrical Cournot
oligopoly game-theoretic models in normal form. Also, we build and investigate coop27
erative three-player games with the same characteristic ...
