A Field Guide to Federated Optimization

The authors thank the early feedback and review by Sean Augenstein, Kallista Bonawitz, Corinna Cortes, and Keith Rush. This work is supported by GCP credits provided by Google Cloud. The simulation experiments are implemented with the TensorFlow Federated package. This paper originated at the discussion session moderated by Zheng Xu and Gauri Joshi at the Workshop on Federated Learning and Analytics, virtually held June 29–30th, 2020. During the discussion, a general consensus about the need for a guide about federated optimization is reached.
