Explore the innovative SINDy-RL framework in this 21-minute video lecture by Steve Brunton. Delve into the world of interpretable and efficient model-based reinforcement learning, combining sparse identification of nonlinear dynamics (SINDy) with deep reinforcement learning (DRL). Learn how this approach creates efficient, interpretable, and trustworthy representations of dynamics models, reward functions, and control policies. Discover the advantages of SINDy-RL over traditional DRL methods, including reduced data requirements and smaller, more interpretable control policies. Follow along as the lecture covers reinforcement learning basics, its drawbacks, dictionary learning, and the various components of SINDy-RL, including environment modeling, reward function approximation, agent design, and uncertainty quantification. Gain insights into how this method can be applied to benchmark control environments and challenging fluids problems, potentially revolutionizing control strategies in complex systems like tokamak fusion reactors and fluid dynamics.
