> genpark-actor-critic-advantage-td-error-skill — alpha-park-genpark-actor-critic-advantage-td-error-skill. Use this tool when you need to estimate advantages in reinforcement learning using TD error and update policies with softmax gradients. It solves problems in policy optimization and value estimation, particularly in episodic or continuous tasks. The tool takes in state-action pairs and rewards as inputs and outputs updated policy parameters and estimated advantages.
