Research Abstract:

Title: Interactive Online Learning for Intelligent Systems

The past several years have witnessed a growing need for intelligent systems that work in real-time to satisfy people’s various needs. Most existing learning solutions in such systems are passive and offline. However, due to the heterogeneity and dynamic nature of users, a generic offline trained algorithm can hardly satisfy each individual user’s need, which calls for interactive online learning solutions. Online learning solutions explore the unknowns by sequentially collect individual user’s feedback. It helps address the notorious explore/exploit dilemma during sequential decision making. My research goal is to build a new interactive online learning paradigm for information service systems. This interactive online learning paradigm can be applied to a wide spectrum of applications, including modern recommender systems, interactive online education systems, human-in-the-loop cyber-physical systems and many more.
