(Track1) Federated Learning and Analytics: Industry Meets Academia Q&A

Peter Kairouz · Brendan McMahan · Virginia Smith


Federated learning (FL) is a machine learning setting where many clients (e.g. mobile devices or whole organizations) collaboratively train a model under the orchestration of a central server (e.g. service provider), while keeping the training data decentralized. Similarly, federated analytics (FA) allows data scientists to generate analytical insight from the combined information in distributed datasets without requiring data centralization. Federated approaches embody the principles of focused data collection and minimization, and can mitigate many of the systemic privacy risks and costs resulting from traditional, centralized machine learning and data science approaches.

Motivated by the explosive growth in federated learning and analytics research, this tutorial will provide a gentle introduction to the area. The focus will be on cross-device federated learning, including deep dives on federated optimization and differentially privacy, but federated analytics and cross-silo federated learning will also be discussed. In addition to optimization and privacy, we will also introduce personalization, robustness, fairness, and systems challenges in the federated setting with an emphasis on open problems.
