## ✨ Overview
- [x] **📖 RL paradigm-based Explainable RL Taxonomy**
- [x] **👓 Review of human knowledge-based RL explainability**
- [x] **🚀 List of Current XRL research literatures and codes links**
In this survey, we provide a comprehensive review of existing works on eXplainable Reinforcement Learning (XRL) and introduce a new taxonomy where prior works are clearly categorized into agent model-explaining, reward-explaining, state-explaining, and task-explaining methods. We also review and highlight RL methods that conversely leverage human knowledge to promote learning efficiency and performance of agents while this kind of method is often ignored in XRL field.
To know more about existing XRL framework and our taxonomy, the existing XRL papers within different typs are listed below and summerized in the next Figure. These literatures are categorize into our taxonomy. For each paper, we also include a link to its open-source code if available.
