Bridging Identification and Second-Order Acceleration: A Fast Alternating Minimization Framework for Composite Optimization
Zihao Xia, Min Tao
We consider a class of composite optimization problems involving a smooth function and a proper, lower semicontinuous regularizer, which may be nonconvex and nonsmooth. We propose…

A Single-loop Proximal Subgradient Algorithm for A Class Structured Fractional Programs
Deren Han, Min Tao, Zihao Xia
In this paper, we investigate a class of nonconvex and nonsmooth fractional programming problems, where the numerator composed of two parts: a convex, nonsmooth function and a diff…

On Partly Smoothness, Activity Identification and Faster Algorithms of over Minimization
Min Tao, Xiao-Ping Zhang, Zi-Hao Xia
The norm ratio arose as a sparseness measure and attracted a considerable amount of attention due to three merits: (i) sharper approximations of compared to the $L_…
