## An Inexact Proximal-indefinite Stochastic ADMM

In this paper, we develop an Inexact Proximal-indefinite Stochastic ADMM (IPS-ADMM) for solving a class of separable convex optimization problems whose objective functions consist of two parts: one is an average of many smooth convex functions and another is a convex but possibly nonsmooth function. The involved smooth subproblem is tackled by an inexact accelerated … Read more
