Certified Residual Quasi-Newton Methods for Distributed Variational Inequalities

Ewsey R. Obzherin, Roman M. Mozhaev, Alexander V. Gasnikov +3

Second-order methods for smooth monotone variational inequalities reach the optimal rate $O (T^{- 3/2})$ , but a distributed exact Jacobian costs $d$ times more communication than an…

Application of Optimal Inexact Second-Order Acceleration to Distributed Stochastic Optimization under Statistical Similarity

Yury A. Sokolov, Maxim K. Mashtaler, Alexander V. Gasnikov +3

We consider distributed stochastic convex optimization with a fixed budget of $N$ independent samples split among $m$ workers. Sample average approximation reduces the problem to a…
