Faster Stochastic Algorithms for Minimax Optimization under Polyak--Åojasiewicz Conditions

Lesi Chen, Boyuan Yao, Luo Luo

This paper considers stochastic first-order algorithms for minimax optimization under Polyak--Åojasiewicz (PL) conditions. We propose SPIDER-GDA for solving the finite-sum problem…

On the Complexity of Decentralized Smooth Nonconvex Finite-Sum Optimization

Luo Luo, Yunyan Bai, Lesi Chen +2

We study the decentralized optimization problem $min_{x \in R^{d}} f (x) ≜ \frac{1}{m} \sum_{i = 1}^{m} f_{i} (x)$ , where the local function on the $i$ -th a…
