报告摘要：In this talk, our recent researches on a deterministic alternating direction method of multipliers (ADMM) and two stochastic ADMMs are presented for solving the muti-block structured convex optimization problems whose objective functions are possibly nonsmooth. The main convergence results of these methods are showed concisely. Performance of the methods is verified by testing the latent variable Gaussian graphical model selection problem in statistical learning and the graph-guided fused lasso problem in supervised learning, respectively. Finally, several further questions are shared and discussed.
