Global Stability and Step Size Robustness of RMSProp

Optimization and Control 2026-05-19 v2

Abstract

In this paper, an input-to-state Lyapunov function for the RMSProp optimization algorithm is introduced. Global asymptotic stability of the RMSProp algorithm for constant step sizes and robustness properties with respect to arbitrary bounded time-varying step size rules are established.
