Accelerated Stochastic ExtraGradient: Mixing Hessian and Gradient Similarity to Reduce Communication in Distributed and Federated Learning

Autor: Bylinkin, Dmitry, Degtyarev, Kirill, Beznosikov, Aleksandr

Modern realities and trends in learning require more and more generalization ability of models, which leads to an increase in both models and training sample size. It is already difficult to solve such tasks in a single device mode. This is the reaso

Autor: Degtyarev Kirill, Kiseleva Sophia, Nefedova Liudmila, Berezkin Mikhail, Sinyugin Oleg

Publikováno v: E3S Web of Conferences, Vol 407, p 03003 (2023)

Тhe article contains the estimation of global investment costs required for the global energy transition to zero-carbon economy by 2050. The evaluations are based on the data on global energy supply and its forecast to 2050, assumption that all the

Method of discrete singularities in problems of filler vibrations in fuel tanks under overloads and at low gravity

Autor: Myronenko Maria L., Gnitko Vasyl I., Degtyarev Kirill G.

Publikováno v: Вісник Харківського національного університету імені В.Н. Каразіна. Серія: Математичне моделювання, інформаційні технології, автоматизовані системи управління, Iss 41 (2019)

The paper is about free vibration problems in fuel tanks with different levels of fillers both under overloads and low gravity. The fuel tanks are considered as rigid shells of revolution. The liquid, contained in the tanks, is supposed to be an idea

Spectral-line Survey of the Region of Massive Star Formation W51e1/e2 in the 4 mm Wavelength Range

Autor: Kalenskii, Sergei. V., Kaiser, Ralf I., Bergman, Per, Olofsson, A. O. Henrik, Degtyarev, Kirill D., Golysheva, Polina

We present the results of a spectral-line survey of the W51e1/e2 star-forming region at 68-88 GHz. 79 molecules and their isotopologues were detected, from simple diatomic or triatomic molecules, such as SO, SiO, and CCH, to complex organic compounds
