Decentralized Finite-Sum Optimization over Time-Varying Networks
Dmitry Metelev, Savelii Chezhegov, Alexander Rogozin +4
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 s…
Decentralized Optimization Over Slowly Time-Varying Graphs: Algorithms and Lower Bounds
Dmitry Metelev, Aleksandr Beznosikov, Alexander Rogozin +2
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…
Decentralized Saddle-Point Problems with Different Constants of Strong Convexity and Strong Concavity
Dmitriy Metelev, Alexander Rogozin, Alexander Gasnikov +1
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…
