报告摘要：

In this talk, several stochastic versions on the alternating direction method of multipliers and the Peaceman-Rachford splitting method are presented for a class of structured convex optimization problems whose objective function is the sum of a possibly nonsmooth convex function and an average function of many smooth convex functions. We show the main convergence results of these methods and their performance on testing the popular empirical risk minimization problem in supervised learning and the 3D CT reconstruction problem in medical imaging, respectively. Finally, several interesting questions are shared and discussed.
