Title

MaLGa Colloquia - The Statistical Complexity of Interactive Decision Making

Speaker

Alexander (Sasha) Rakhlin - Massachusetts Institute of Technology

Abstract

In this talk, we will present a new emerging framework for interactive decision making. We will examine multi-armed bandits, contextual bandits, structured bandits, general decision making, and reinforcement learning under the same umbrella. We will present (i) sample complexity measures for interactive decision making that are necessary and sufficient for sample-efficient learning, and (ii) unified algorithm design principles that achieve optimal sample complexity.
