The blog post by Piotr Januszewski explores the utilization of deep reinforcement learning for continuous control tasks, such as making a humanoid model walk, contrasting it with discrete action tasks like playing Atari games. It introduces continuous control environments and delves into the actor-critic architecture, specifically focusing on the Soft Actor-Critic (SAC) method, which is implemented in the SpinningUp framework. The post explains the differences between on-policy and off-policy methods, highlighting SAC's sample efficiency due to its off-policy nature and experience replay buffer. The article includes a practical example of training an SAC agent in the Pendulum-v0 environment from OpenAI Gym, with detailed pseudo-code and implementation instructions. It concludes by encouraging readers to experiment with more complex environments like Humanoid, using the MuJoCo simulation engine, and suggests optimizing hyper-parameters for better performance.
