Explore model-based reinforcement learning with value-targeted regression in this 36-minute lecture by Mengdi Wang from Princeton University. Delve into episodic reinforcement learning, upper confidence model-based RL (UCRL), and deterministic continuous systems. Examine the MatrixRL algorithm, feature space embedding of transition models, and kernel embedding techniques. Investigate the motivating example of MuZero and the assumptions behind value-targeted regression. Learn about confidence set construction using VTR and analyze the regret of UCRL-VTR. Gain insights into the mathematics of online decision-making and advanced reinforcement learning concepts.
