WebExport citation Abstract In this paper, we develop a symmetric accelerated stochastic Alternating Direction Method of Multipliers (SAS-ADMM) for solving separable convex optimization problems with linear constraints. The objective function is the sum of a possibly nonsmooth convex function and an average function of many smooth convex functions. Webare given in AppendixA.5, has discussed convergence properties of inexact ADMM. As a consequence, we only need to make sure each sub-problem has been well optimized. In the case of consensus ADMM, the algorithm is guaranteed to reach optimal value so long as tB[t+ 1] argmin B L( [t];B;D[t]) 2 ; for a summable sequence of thresholds P t <1.
