A Hybrid Variance-Reduced Method for Decentralized Stochastic Non-Convex Optimization

ICML 2021spotlight

This paper considers decentralized stochastic optimization over a network of $n$ nodes, where each node possesses a smooth non-convex local cost function and the goal of the networked nodes is to find an $\epsilon$-accurate first-order stationary point of the sum of the local costs. We focus on an o…
