This repository is the official implementation of the paper 'DRIVE: One-bit Distributed Mean Estimation', which was published at NeurIPS 2021.

DRIVE is a 1-bit compression algorithm for distributed mean estimation. When applied to various distributed and specifically federated learning tasks, it shows consistent improvement over the state of the art.

drive_tf and drive_torch folders contain our standalone implementation for TensorFlow and PyTorch, respectively.

The experiments folder contains details on how to reproduce the paper's results. It is separated into two sub-projects:

1. The distributed sub-folder contains all the distributed learning experiments (Distributed CNN, K-means, Power Iteration) using PyTorch.
2. The federated sub-folder contains the federated learning experiments using TensorFlow.
