Safe-EF: Error Feedback for Nonsmooth Constrained Optimization arXiv:2505.06053v1 Announce Type: cross Abstract: Federated learning faces severe communication bottlenecks due to the high dimensionality of model updates. Communication compression with contractive compressors (e.g., Top-K) is often preferable in practice but can degrade performance without proper handling. Error feedback (EF) mitigates such issues but has been largely…
