Decentralized Stochastic Proximal Gradient Descent with Variance Reduction over Time-varying Networks

no code implementations20 Dec 2021 Xuanjie Li, Yuedong Xu, Jessie Hui Wang, Xin Wang, John C. S. Lui

By transforming our decentralized algorithm into a centralized inexact proximal gradient algorithm with variance reduction, and controlling the bounds of error sequences, we prove that DPSVRG converges at the rate of $O(1/T)$ for general convex objectives plus a non-smooth term with $T$ as the number of iterations, while DSPG converges at the rate $O(\frac{1}{\sqrt{T}})$.

Toward Packet Routing with Fully-distributed Multi-agent Deep Reinforcement Learning

no code implementations9 May 2019 Xinyu You, Xuanjie Li, Yuedong Xu, Hui Feng, Jin Zhao, Huaicheng Yan

Packet routing is one of the fundamental problems in computer networks in which a router determines the next-hop of each packet in the queue to get it as quickly as possible to its destination.
