Convergence analysis of the Riemannian proximal gradient method with inexact oracle
Chao Huang, Xiyuan Xie, Anna Qi +2
We extend the notion of an inexact first-order oracle from the Euclidean setting to Riemannian optimization, and conduct a convergence analysis for the Riemannian proximal gradient…

A proximal algorithm incorporating difference of convex functions optimization for solving a class of single-ratio fractional programming
Anna Qi, Jianfeng Huang, Lihua Yang +1
In this paper, we consider a class of single-ratio fractional minimization problems, where both the numerator and denominator of the objective are convex functions satisfying posit…
