Stochastic Gradient Descent Ascent is Suboptimal for Nonconvex-PL Min-Max Games

arXiv:2610.07814v1 Announce Type: new Abstract: How far can stochastic gradient descent ascent (SGDA) go by tuning its timescale ratio and step sizes in nonconvex min-max games? We answer this question for nonconvex-PL (NC-PL) games by establishing the first tight complexity of two-timescale SGDA w…
