Iteratively Linearized Reweighted Alternating Direction Method of Multipliers for a Class of Nonconvex Problems

Tao Sun, Hao Jiang, Lizhi Cheng +1

In this paper, we consider solving a class of nonconvex and nonsmooth problems frequently appearing in signal processing and machine learning research. The traditional alternating…

A note on alternating minimization algorithms: Bregman frame

Tao Sun, Lizhi Cheng

In this paper, we propose a Bregman frame for several classical alternating minimization algorithms. In the frame, these algorithms have uniform mathematical formulation. We also p…

A note on the convergence of nonconvex line search

Tao Sun, Lizhi Chenga, Hao Jiang

In this note, we consider the line search for a class of abstract nonconvex algorithm which have been deeply studied in the Kurdyka-Lojasiewicz theory. We provide a weak convergenc…
