Ketnote Title - Distributed Machine Learning and Network Resource Allocation for Intelligent Edge Services

Speaker - Prof. Iordanis Koutsopoulos
Department of Informatics, Athens University of Economics and Business

Abstract: In this talk, we outline some research areas we work on for the last few years, on the foundations of intelligent trustworthy services at the resource-limited network edge. These questions require new synergies between Artificial Intelligence (AI) and Networking, and they fill the puzzle of ensuring trustworthy services in different sectors with autonomous vehicles, robotics, health, energy, agriculture, and more. Important milestones towards this goal are low-latency inference, personalization, explainability, continual model updates, energy efficiency, and low-latency communication with a network controller. Specifically, we will talk about: (1) running Large Language Models (LLMs) over a network of resource-constrained devices for low-latency inference; (2) developing new architectures for Split Federated Learning, by splitting and parallelizing the workload of training across devices; (3) achieving exact optimization in training personalized models with Federated Learning; (4) addressing both explainability and accuracy through a Multi-objective optimization framework; (5) introducing network awareness in Continual Learning; (6) using Multi-armed bandits to learn the optimal controller placement in Software-Defined Networks, and the optimal offloading policy for image processing tasks. We conclude with a prototype of a Digital Twin for a wireless network testbed and work on agentic AI, and we pave the way ahead.
