Federated Differentially Private Optimization via Low-Rank Preconditioning

Year: 2026 • Source: arxiv.org • Listed PDF

We consider differentially private (DP) optimization in the federated setting, where a DP estimate of the feature covariance matrix serves as a Hessian approximation for generalized linear models. Existing central DP met...
