Preference-based reinforcement learning (RL) is an approach to learning reward models from pairwise comparisons of behaviors, eliminating the need for explicit reward design. However, existing methods often rely on passive data collection, resulting in poor sample efficiency, particularly during the early stages of learning. The proposed method, Uncertainty-Balanced Preference Planning (UBP2), addresses this issue by using ensembles of reward, dynamics, and value function models to evaluate uncertainties. UBP2 is a model-based approach that actively directs exploration by jointly reasoning over these uncertainties. This approach enables more efficient learning and improved performance in preference-based RL. The introduction of UBP2 has the potential to enhance the field of RL by providing a more efficient and effective method for learning from preferences.
