Inexact Accelerated Proximal Gradient Method Revisit: An Economical Variant via Shadow Points
Lei Yang, Meixia Lin
We consider the problem of optimizing the sum of a smooth convex function and a non-smooth convex function via the inexact accelerated proximal gradient (APG) method. A key limitat…

An Inexact Variable Metric Proximal Gradient-subgradient Algorithm for a Class of Fractional Optimization Problems
Lei Yang, Xiangrui Kong, Min Zhang +1
In this paper, we study a class of fractional optimization problems, in which the numerator of the objective is the sum of a convex function and a differentiable function with a Li…
