Communication-efficient Variance-reduced Stochastic Gradient Descent

2020 · KTH Publication Database DiVA (KTH Royal Institute of Technology)

We consider the problem of communication efficient distributed optimization where multiple nodes exchange important algorithm information in every iteration to solve large problems. In particular, we focus on the stochastic variance-reduced gradient and propose a …
Optimal convergence rates of totally asynchronous optimization

2022 · arXiv (Cornell University)

Asynchronous optimization algorithms are at the core of modern machine learning and resource allocation systems. However, most convergence results consider bounded information delays and several important algorithms lack guarantees when they operate under total asynchrony. …
