Projected Federated Averaging with Heterogeneous Differential Privacy
Summary: Introduces PFA for federated learning with heterogeneous differential privacy, projecting private updates onto the top singular subspace from public clients before aggregation. PFA+ enables uploading projected updates, achieving over 99% uplink reduction with preserved utility. (summarized by gpt-5-nano on Feb 09 2026)
