Tight Convergence Rates in Gradient Mapping for the Difference-of-Convex Algorithm

Teodor Rotaru, Panagiotis Patrinos, François Glineur

We establish new theoretical convergence guarantees for the difference-of-convex algorithm (DCA), where the second function is allowed to be weakly-convex, measuring progress via c…

Tight Analysis of Difference-of-Convex Algorithm (DCA) Improves Convergence Rates for Proximal Gradient Descent

Teodor Rotaru, Panagiotis Patrinos, François Glineur

We investigate a difference-of-convex (DC) formulation where the second term is allowed to be weakly convex. We examine the precise behavior of a single iteration of the difference…

Exact worst-case convergence rates of gradient descent: a complete analysis for all constant stepsizes over nonconvex and convex functions

Teodor Rotaru, François Glineur, Panagiotis Patrinos

We consider gradient descent with constant stepsizes and derive exact worst-case convergence rates on the minimum gradient norm of the iterates. Our analysis covers all possible st…

Improved convergence rates for the Difference-of-Convex algorithm

Teodor Rotaru, Panagiotis Patrinos, François Glineur

We consider a difference-of-convex formulation where one of the terms is allowed to be hypoconvex (or weakly convex). We first examine the precise behavior of a single iteration of…

Tight convergence rates of the gradient method on smooth hypoconvex functions

Teodor Rotaru, François Glineur, Panagiotis Patrinos

We perform the first tight convergence analysis of the gradient method with varying step sizes when applied to smooth hypoconvex (weakly convex) functions. Hypoconvex functions are…
