On the Convergence of (Stochastic) Gradient Descent with Extrapolation for Non-Convex Optimization

Yi Xu, Zhuoning Yuan, Sen Yang +2

Extrapolation is a well-known technique for solving convex optimization and variational inequalities and recently attracts some attention for non-convex optimization. Several recen…

Homotopy Smoothing for Non-Smooth Problems with Lower Complexity than $O (1/ ε)$

Yi Xu, Yan Yan, Qihang Lin +1

In this paper, we develop a novel {\bf ho}moto{\bf p}y {\bf s}moothing (HOPS) algorithm for solving a family of non-smooth problems that is composed of a non-smooth term with an ex…
