This paper makes complex Multi-objective reinforcement learning (MORL) policies understandable by clustering them based on both behavior and objectives
When AI gives you too many options, this clustering trick saves the day
Original Problem:
Multi-objective reinforcement learning (MORL) generates multiple policies with different trade-offs, but these solution sets are too large and complex for humans to analyze effectively. Decision makers struggle to understand relationships between policy behaviors and their objective outcomes.
-----
Solution in this Paper:
→ Introduces a novel clustering approach that considers both objective space (expected returns) and behavior space (policy actions)
→ Uses Highlights algorithm to capture 5 key states that represent each policy's behavior
→ Applies PAN (Pareto-Set Analysis) clustering to find well-defined clusters in both spaces simultaneously
→ Employs bi-objective evolutionary algorithm to optimize clustering quality across both spaces
-----
Key Insights:
→ First research to tackle MORL solution set explainability
→ Different policies with similar trade-offs can exhibit vastly different behaviors
→ Combining objective and behavior analysis reveals deeper policy insights
→ Makes MORL more practical for real-world applications
-----
Results:
→ Outperformed traditional k-medoids clustering in MO-Highway and MO-Lunar-lander environments
→ Showed comparable performance in MO-Reacher and MO-Minecart scenarios
→ Successfully demonstrated practical application through highway environment case study
