The Privacy Power of Correlated Noise in Decentralized Learning

1 code implementation2 May 2024 Youssef Allouah, Anastasia Koloskova, Aymane El Firdoussi, Martin Jaggi, Rachid Guerraoui

Decentralized learning is appealing as it enables the scalable usage of large amounts of distributed data and resources (without resorting to any central entity), while promoting privacy since every user minimizes the direct exposure of their data.

Tackling Byzantine Clients in Federated Learning

no code implementations20 Feb 2024 Youssef Allouah, Sadegh Farhadkhani, Rachid Guerraoui, Nirupam Gupta, Rafael Pinot, Geovani Rizk, Sasha Voitovych

The natural approach to robustify FL against adversarial clients is to replace the simple averaging operation at the server in the standard $\mathsf{FedAvg}$ algorithm by a \emph{robust averaging rule}.

Robustness, Efficiency, or Privacy: Pick Two in Machine Learning

no code implementations22 Dec 2023 Youssef Allouah, Rachid Guerraoui, John Stephan

The success of machine learning (ML) applications relies on vast datasets and distributed architectures which, as they grow, present major challenges.

Computational Efficiency Data Poisoning

On the Privacy-Robustness-Utility Trilemma in Distributed Learning

no code implementations9 Feb 2023 Youssef Allouah, Rachid Guerraoui, Nirupam Gupta, Rafael Pinot, John Stephan

The latter amortizes the dependence on the dimension in the error (caused by adversarial workers and DP), while being agnostic to the statistical properties of the data.

Fixing by Mixing: A Recipe for Optimal Byzantine ML under Heterogeneity

no code implementations3 Feb 2023 Youssef Allouah, Sadegh Farhadkhani, Rachid Guerraoui, Nirupam Gupta, Rafael Pinot, John Stephan

Byzantine machine learning (ML) aims to ensure the resilience of distributed learning algorithms to misbehaving (or Byzantine) machines.
