Trustworthy Online Learning for Networked Systems

ABSTRACT

In the age of ubiquitous connectivity, networked systems, from data networks to edge/mobile/cloud computing, have reached unprecedented complexity and scale. Traditional methods for network control and resource allocation, often based on static models, struggle with the dynamic nature of modern networks. Machine learning, with its ability to refine models over time, emerges as a transformative solution. In this talk, I will introduce my research on developing efficient, scalable, and trustworthy online learning algorithms for learning-enabled networked systems, focusing on two critical challenges, scalability and trustworthiness. For scalability, as the size and complexity of networked systems increase, the learning efficiency tends to decrease significantly. I will introduce my combinatorial online learning approaches with theoretical guarantees, demonstrating their effectiveness in real-world systems like wireless and social networks. For trustworthiness, I will delve into the unreliable behavior of devices in networked systems, showcasing my findings on the vulnerabilities of existing multi-agent online learning algorithms. Finally, I will discuss how trustworthy online learning can reshape network intelligence, driving more adaptive, resilient, and secure systems.
