This paper introduces Byrd-NAFL, a federated learning algorithm that combines Nesterov acceleration with Byzantine-resilient aggregation to improve convergence speed and robustness against malicious gradient attacks. Theoretical analysis confirms finite-time convergence under non-convex loss functions, while experiments demonstrate superior performance over existing benchmarks in accuracy and resilience.
A Nesterov-Accelerated Byzantine-Robust Federated Learning
arXiv:2511.02657v2 Announce Type: replace Abstract: We investigate robust federated learning, where a group of workers collaboratively train a shared model under the orchestration of a central server in the presence of Byzantine adversaries capable of arbitrary and potentially malicious behaviors. To simultaneously enhance communication efficiency and resilience against such adversaries, we propose a Byzantine-resilient Nesterov-accelerated federated learning (Byrd-NAFL) algorithm. Byrd-NAFL seamlessly integrates Nesterov's momentum into the federated learning process alongside Byzantine-resilient aggregation rules to achieve fast and safe convergence against gradient corruption. We establish a finite-time convergence guarantee for Byrd-NAFL under non-convex and smooth loss functions with relaxed assumptions on the aggregated gradients. Extensive numerical experiments validate the effectiveness of Byrd-NAFL and demonstrate the superiority over existing benchmarks in terms of convergence speed, accuracy, and resilience to diverse malicious attacks.
