We consider decentralized time-varying stochastic optimization problems where each of the functions held by the nodes has a finite sum structure. Such problems can be efficiently solved using variance reduction techniques. Our aim is to explore the l

The article examines the implementation of one of the most important axiological foundations of higher education – the formation of attitudes among students towards public service as a social value. The relevance of the study is due to the need to

Distributed optimization is an important direction of research in modern optimization theory. Its applications include large scale machine learning, distributed signal processing and many others. The paper studies decentralized min-max optimization f

We consider a decentralized convex unconstrained optimization problem, where the cost function can be decomposed into a sum of strongly convex and smooth functions, associated with individual agents, interacting over a static or time-varying network.

We consider decentralized optimization problems where one aims to minimize a sum of convex smooth objective functions distributed between nodes in the network. The links in the network can change from time to time. For the setting when the amount of

The article presents two case reports of pulmonary embolism in patients with viral pneumonia. In one case, in a coronavirus disease 2019 (COVID-19) survivor, while in the second case — in a patient with influenza. A comparative analysis of thromboe

Large-scale saddle-point problems arise in such machine learning tasks as GANs and linear models with affine constraints. In this paper, we study distributed saddle-point problems (SPP) with strongly-convex-strongly-concave smooth objectives that hav

Digital array orthogonal transformations that can be presented as a decomposition over basis items or basis images are considered. The orthogonal transform provides digital data scattering, a process of pixel energy redistributing, that is illustrate

Metelev et al. use single-molecule tracking to study kinetics of translation directly in E. coli cells, and how it is affected by translation inhibitors and rRNA mutations. Their results support widespread 70S re-initiation on mRNAs.
