Abstract
Stochastic dynamic system models have widespread applications in settings such as robotics, autonomous vehicles, power grids, and wireless communications. Today’s dynamic systems are often large, very uncertain, decentralized, with many unknown parameters. Decision making in such systems presents significant challenges, since many traditional methods, developed with a focus on much smaller systems, either cannot be applied or can be computationally intensive or data inefficient. My research aims at developing new theories and algorithms to meet the challenges of data-driven decision making in today’s large scale multi-agent systems. In this talk, I will discuss my contributions in (1) reinforcement learning algorithms and multi-armed bandits, where I devise novel, principled data-driven algorithms; (2) information states for multi-agent dynamic games, where I develop structural results and provide new insights; (3) planning for multi-agent dynamic systems, where I develop efficient algorithms for multi-agent teams; (4) dispatching algorithms for multi-server cloud computing centers, where I proposed and systematically analyzed a low-randomness dispatching algorithm. Finally, I will outline my expertise and future research plans that will serve my ultimate goal of enabling well-functioning large-scale dynamic systems.
