Explore hyperparameter optimization for reinforcement learning using Meta's Ax framework in this comprehensive 58-minute tutorial. Learn about the three basic HPO techniques: grid search, random search, and Bayesian optimization. Dive into practical implementation using Python, including package installation, environment setup, and configuration of Weights & Biases. Follow along as the instructor demonstrates loading and testing a pendulum gymnasium environment, defining trials for agent training and testing, and setting up an Ax experiment for Bayesian optimization. Gain insights into debugging, training agents with optimized hyperparameters, and running additional trials. Conclude with an introduction to Weights & Biases sweeps for further optimization techniques.
