Abstract: This seminar is in two related parts. The first part discusses models for sequential decision-making involving social learning. We also discuss sequential detection involving multi-agent decision-makers and rational inattention models.
The second part of the talk discusses inverse reinforcement learning (IRL) – namely how to estimate the utility function of a decision maker given its decisions. We discuss revealed preferences and Afriat’s theorem from microeconomics for IRL and also Bayesian IRL methods to detect the presence of a sequential detector from its decisions. As an illustrative example, we discuss multimedia user engagement.
Bio: Vikram Krishnamurthy is a professor at Cornell University. His research interests are in statistical signal processing, stochastic optimization and adaptive sensing. From 2002-2016 he was a Professor and Canada Research Chair at the University of British Columbia, Canada.
