SCAFFLSA: Taming Heterogeneity in Federated Linear Stochastic Approximation and TD Learning

no code implementations6 Feb 2024 Paul Mangold, Sergey Samsonov, Safwan Labbi, Ilya Levin, REDA ALAMI, Alexey Naumov, Eric Moulines

In this paper, we analyze the sample and communication complexity of the federated linear stochastic approximation (FedLSA) algorithm.

The Relative Gaussian Mechanism and its Application to Private Gradient Descent

no code implementations29 Aug 2023 Hadrien Hendrikx, Paul Mangold, Aurélien Bellet

Leveraging this assumption, we introduce the Relative Gaussian Mechanism (RGM), in which the variance of the noise depends on the norm of the output.

Differentially Private Coordinate Descent for Composite Empirical Risk Minimization

no code implementations22 Oct 2021 Paul Mangold, Aurélien Bellet, Joseph Salmon, Marc Tommasi

In this paper, we propose Differentially Private proximal Coordinate Descent (DP-CD), a new method to solve composite DP-ERM problems.
