Hyper-Sphere Quantization: Communication-Efficient SGD for Federated Learning

1 code implementation12 Nov 2019 Xinyan Dai, Xiao Yan, Kaiwen Zhou, Han Yang, Kelvin K. W. Ng, James Cheng, Yu Fan

In particular, at the high compression ratio end, HSQ provides a low per-iteration communication cost of $O(\log d)$, which is favorable for federated learning.
