Distributed Machine Learning Over-the-Air: A Tale of Interference<\/p>

Abstract<\/strong><\/p>

This talk aims to present the current research efforts on the development of implementing 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 machine learning (OTA-ML). We will present the general architecture, model training algorithm, and an analytical framework that quantifies the convergence rate of OTA-ML. The analysis takes into account key effects from wireless transmissions, namely, channel fading and interference, on the convergence performance and discloses how interference is deteriorating the model training process. Then, we elaborate on several improvements to the OTA-ML from different aspects. Particularly, we discuss the system enhancements from an algorithmic perspective, e.g., adopting the momentum-based approach and\/or adaptive optimizations to accelerate the model training. We also introduce model pruning schemes that reduce the computation and communication overheads for OTA-ML. Finally, we will elaborate on the analysis of generalization error of the statistical models trained by OTA-ML, which shows that wireless interference has the positive potential of improving the generalization capability. We will conclude this tutorial by shedding light on future works.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
