MAB-Based Channel Scheduling for Asynchronous Federated Learning in Non-Stationary Environments

no code implementations3 Mar 2025 Zhiyin Li, Yubo Yang, Tao Yang, Xiaofeng Wu, Ziyu Guo, Bo Hu

To address these challenges, we propose an asynchronous federated learning scheduling framework for non-stationary channel environments to reduce staleness while promoting fair and efficient communication and aggregation. We focus on two channel scenarios: extremely non-stationary and piecewise stationary.
