Choco-SGD

This repository provides code for communication-efficient decentralized ML training (both deep learning, compatible with PyTorch, and traditional convex machine learning models.

We provide code for the main experiments in the papers

• Decentralized Stochastic Optimization and Gossip Algorithms with Compressed Communication and
• Decentralized Deep Learning with Arbitrary Communication Compression.

Please refer to the folders convex_code and dl_code for more details.
