A Single-Loop Smoothed Gradient Descent-Ascent Algorithm for Nonconvex-Concave Min-Max Problems

no code implementations NeurIPS 2020 Jiawei Zhang, Peijun Xiao, Ruoyu Sun, Zhi-Quan Luo

We prove that the stabilized GDA algorithm can achieve an $O(1/\epsilon^2)$ iteration complexity for minimizing the pointwise maximum of a finite collection of nonconvex functions.

DEED: A General Quantization Scheme for Communication Efficiency in Bits

no code implementations19 Jun 2020 Tian Ye, Peijun Xiao, Ruoyu Sun

In the infrequent communication setting, DEED combined with Federated averaging requires a smaller total number of bits than Federated Averaging.

Understanding Limitation of Two Symmetrized Orders by Worst-case Complexity

no code implementations10 Oct 2019 Peijun Xiao, Zhisheng Xiao, Ruoyu Sun

Recently, Coordinate Descent (CD) with cyclic order was shown to be $O(n^2)$ times slower than randomized versions in the worst-case.
