What Is the Statistical Complexity of Reinforcement Learning?

Explore the statistical complexity of reinforcement learning in this 53-minute lecture by Sham Kakade from Harvard and Microsoft Research. Delve into the fundamental question of what conditions enable generalization and avoid the curse of dimensionality in reinforcement learning. Compare the well-understood theoretical foundations of supervised learning with the challenges in reinforcement learning. Examine recent advances in characterizing when generalization is possible in both online and offline reinforcement learning settings. Learn about the newly introduced complexity measure, the Decision-Estimation Coefficient, and its significance in sample-efficient interactive learning. Cover topics such as linear methods, sufficient conditions, bilinear classes, and intuition behind complexity measures in reinforcement learning.
