Variance reduced stochastic optimization over directed graphs with row and column stochastic weights
Muhammad I. Qureshi, Ran Xin, Soummya Kar +1
This paper proposes AB-SAGA, a first-order distributed stochastic optimization method to minimize a finite-sum of smooth and strongly convex functions distributed over an arbitrary…

Distributed saddle point problems for strongly concave-convex functions
Muhammad I. Qureshi, Usman A. Khan
In this paper, we propose GT-GDA, a distributed optimization method to solve saddle point problems of the form: $\min_{\mathbf{x}} \max_{\mathbf{y}} \{F(\mathbf{x},\mathbf{y}) :=G(…
