### vqSGD: Vector Quantized Stochastic Gradient Descent. (arXiv:1911.07971v1 [cs.LG])

In this work, we present a family of vector quantization schemes vqSGD (Vector-Quantized Stochastic Gradient Descent) that provide asymptotic reduction in the communication cost with convergence guarantees in distributed computation and learning settings. In particular, we consider a randomized scheme, based on convex hull of a point set, that returns an unbiased estimator of a…
