Federated Learning Over the Air: A Tale of Interference

June 10, 2024 10:00 AM Singapore (Registration starts at 9:50 AM)


This talk aims to present the current research efforts on the development of implementing distributed machine learning algorithms in wireless systems. Specifically, we provide a comprehensive coverage of a distributed learning paradigm based on over-the-air computing, a.k.a. over-the-air federated learning (OTA-FL). We will present an analytical framework that quantifies the convergence rate of OTA-FL. Then, we discuss the system enhancements from an algorithmic perspective, i.e., adopting adaptive optimizations to accelerate the model training. We also introduce model pruning schemes that reduce the computation and communication overheads for OTA-FL. Finally, we will elaborate on the analysis of generalization error of the statistical models trained by OTA-FL, which shows that wireless interference has the positive potential of improving the generalization capability.
