Data Heterogeneity-Aware Client Selection for Federated Learning
Analysis
This paper addresses a critical challenge in Federated Learning (FL): data heterogeneity among clients in wireless networks. It provides a theoretical analysis of how this heterogeneity impacts model generalization, leading to inefficiencies. The proposed solution, a joint client selection and resource allocation (CSRA) approach, aims to mitigate these issues by optimizing for reduced latency, energy consumption, and improved accuracy. The paper's significance lies in its focus on practical constraints of FL in wireless environments and its development of a concrete solution to address data heterogeneity.
