Distributed Learning and Inference over Wireless Channels


Edge devices collect massive amounts of data, opening up new potentials for machine learning applications. Machine learning at the edge can benefit from exploiting both data and processing power distributed across many wireless devices, but this brings about many new challenges including the low latency requirements of learning applications, privacy concerns preventing data sharing, and the impact of noise and interference on the convergence of the learning process. Overcoming these challenges while meeting the requirements of the machine learning tasks calls for a new paradigm of semantic-oriented communication network design tailored for learning applications. In this talk, I will present recent results on efficient distributed inference and training over wireless networks taking into account channel impairments and power and bandwidth limitations of wireless devices, as well as the semantics of the underlying learning tasks. This will involve bringing together novel communication and coding techniques with distributed learning and inference algorithms.

6G Intelligent Edge: Shannon Meets Turing


The popularity of mobile devices and densification of wireless networks result in the availability of enormous data and computational resources distributed at the network edge. To leverage the data and resources, machine-learning is deployed at the network edge to train AI models by exploiting the distributed mobile data while preserving their privacy. While computing speeds are advancing rapidly, the communication latency is becoming the bottleneck of fast edge learning. Attempts to overcome the bottleneck have led to the emergence of a new paradigm in wireless communication, “communication efficient edge learning”, which departs from the classic principle of “rate-maximization” and focuses on “fast intelligence acquisition”. In this talk, I will overview new design challenges in the area and highlight some recent advancements in different directions including resource allocation, gradient quantization, feature transmission, wireless data labelling, active data acquisition, and over-the-air computation.
