Zeroth-Order Alternating Gradient Descent Ascent Algorithms for a Class of Nonconvex-Nonconcave Minimax Problems
Zi Xu, Zi-Qi Wang, Jun-Lin Wang +1
In this paper, we consider a class of nonconvex-nonconcave minimax problems, i.e., NC-PL minimax problems, whose objective functions satisfy the Polyak-Łojasiewicz (PL) condition w…

Derivative-free Alternating Projection Algorithms for General Nonconvex-Concave Minimax Problems
Zi Xu, Ziqi Wang, Jingjing Shen +1
In this paper, we study zeroth-order algorithms for nonconvex-concave minimax problems, which have attracted widely attention in machine learning, signal processing and many other…
