Robust Synchronisation for Federated Learning in The Face of Correlated Device Failure

Researchers introduce Availability-Weighted Probabilistic Synchronous Parallel (AW-PSP), an improved federated learning algorithm that addresses bias in node sampling when device availability and data distribution are correlated. The technique uses dynamic probability adjustments, Markov-based failure prediction, and distributed metadata management to improve fairness and robustness in edge computing environments where devices frequently fail or become unavailable.
