Speaker: Prof. Tony Q.S. Quek, IEEE Fellow,Singapore University of Technology and Design

Host: Prof. Ai-Chun Pang 


Machine learning, particularly distributed learning, stands as the cornerstone in the vision of future network intelligence, owing to its remarkable capability of addressing intricate computational tasks and modeling complexities. In this talk, we provide a comprehensive coverage of a distributed learning paradigm rooted in federated learning. Specifically, we start with a brief overview of federated learning, including the general architecture, model training algorithm, and analytical framework that quantifies the convergence rate. Then, we elucidate an over-the-air computation-based variant of federated learning, which circumvents the communication bottleneck by harnessing the superposition properties of wireless channels. Notably, such a scheme presents new advantages, such as reduced processing latency, enhanced privacy protection, and (potentially) better generalization power, demonstrating a possible harmony between wireless communication and distributed learning. We also discuss several approaches to personalize the federated learning framework in accordance with the end-users data distribution, addressing challenges stemming from data heterogeneity. In addition, we showcase a few applications of personalized federated learning in coping with massive random access problems, robustifying over-the-air federated learning, and enhancing the generalization performance with specifically devised communication protocols. Furthermore, we share some of our recent works investigating the interplay between federated learning and foundation models, as well as O-RAN frameworks, poised as versatile platforms that catalyze the practical deployment of foundational models in wireless edge networks.
