Abstract:
Federated learning (FL) becomes increasingly attractive in the areas of wireless communications and machine learning due to its powerful learning ability and potential applications. In contrast to other machine learning techniques that seldom require communication resources, FL exploits communications between the central server and the distributed local clients to train and optimize a model. Therefore, how to efficiently assign limited communication resources to train a FL model is critical to performance optimization. In this talk, we investigate the convergence performance of FL under various communication distortions. After introducing the fundamental tradeoff between efficiency and convergence, we discuss the convergence of FL via inexact ADMM and decentralized FL.
