Researchers have developed a new framework to visualize latent motion phase structures within deep reinforcement learning (DRL) policies for locomotion control. This method extends clustering features beyond just state observations to include actions and next states, and introduces a technique to determine the optimal number of clusters while minimizing self-transitions. When applied to environments like Ant-v5, HalfCheetah-v5, and Walker2D-v5, the proposed approach successfully identified more distinct and regular phase structures compared to existing methods. AI
