Reinforcement learning (RL) often faces challenges with sparse rewards, where the reward is only given when the task is completed. This leads to slow or ineffective RL improvement due to the credit assignment problem. The proposed approach aims to address this by transforming the sparse outcome reward into a dense process reward. This is achieved by training a discriminator to differentiate between previous successful and unsuccessful episodes, allowing for more efficient RL training. The discriminator is trained using success visitation matching, enabling the model to learn from both successful and unsuccessful experiences. The approach has the potential to improve RL efficiency in various applications.

- A type of machine learning where an agent learns to take actions to maximize a reward signal.
- Sparse Rewards
- Rewards that are only given when a specific task or goal is achieved, with no reward given for other actions.
- Credit Assignment Problem
- The challenge of determining which actions or decisions led to a particular outcome or reward in RL.
