Advances and open problems in federated learning

Peter Kairouz, +58 more
TL;DR: In this article, the authors describe the state-of-the-art in the field of federated learning from the perspective of distributed optimization, cryptography, security, differential privacy, fairness, compressed sensing, systems, information theory, and statistics.

Can You Really Backdoor Federated Learning

TL;DR: This paper conducts a comprehensive study of backdoor attacks and defenses for the EMNIST dataset, a real-life, user-partitioned, and non-iid dataset, and shows that norm clipping and "weak'' differential privacy mitigate the attacks without hurting the overall performance.

Hadamard Response: Estimating Distributions Privately, Efficiently, and with Little Communication

TL;DR: Hadamard Response (HR) is proposed, a local privatization scheme that requires no shared randomness and is symmetric with respect to the users, and which runs about 100x faster than Randomized Response, RAPPOR, and subset-selection mechanisms.

Differentially Private Testing of Identity and Closeness of Discrete Distributions

TL;DR: The fundamental problems of identity testing (goodness of fit), and closeness testing (two sample test) of distributions over $k$ elements, under differential privacy are studied, and Le Cam's two point theorem is used to provide a general mechanism for proving lower bounds.
