AGDA+: Proximal Alternating Gradient Descent Ascent Method with a Nonmonotone Adaptive Step-Size Search for Nonconvex Minimax Problems

Xuan Zhang, Qiushui Xu, Necdet Serhat Aybat

We consider double-regularized nonconvex-strongly concave (NCSC) minimax problems of the form $(P) : min_{x \in X} max_{y \in Y} g (x) + f (x, y) - h (y)$ , where $g$ , $h$ ar…

A Stochastic GDA Method With Backtracking For Solving Nonconvex Concave Minimax Problems

Necdet Serhat Aybat, Qiushui Xu, Xuan Zhang +1

We propose a stochastic GDA (gradient descent ascent) method with backtracking (SGDA-B) to solve nonconvex-concave (NCC) minimax problems of the form: $\min_{\mathbf{x}} \max_y \su…
