PushCen-ADFL: Bias-Correction for Asynchronous Federated Learning

ai-technology · 2026-05-27

A recent study published on arXiv introduces PushCen-ADFL, an innovative framework for asynchronous decentralized federated learning (ADFL) that enhances communication efficiency. This framework tackles issues such as high communication costs, biased aggregation, and significant model drift, which arise from frequent peer-to-peer interactions, asynchronous updates on directed networks, and non-IID data. By integrating communication, aggregation, and local stabilization within a shared centroid representation space, it creates a feedback loop between compression and optimization. Clients share messages in centroid form, utilize average-preserving push-sum mixing to address aggregation bias, and implement lightweight centroid regularization to reduce drift amid heterogeneity and uneven communication.
