Zeroth order algorithms for nonconvex minimax problems

19:30-20:30 March 27 (Monday), Tencent Meeting: 332-330-676

In this talk, we briefly introduce the existing zeroth-order algorithms for solving nonconvex minimax problems and their iteration complexity. We also propose some new zeroth-order algorithms for nonconvex-concave minimax problems and prove their complexity. Numerical results show the efficiency of the proposed algorithms.
