UBP2: Efficient Preference-Based RL
Reported by arXiv cs.AI: UBP2: Uncertainty-Balanced Preference Planning for Efficient Preference-based Reinforcement Learning. Analysis and context written by TickrWire.
Researchers introduce UBP2, a model-based approach for efficient preference-based reinforcement learning. UBP2 actively directs exploration by reasoning over uncertainties in reward, dynamics, and value functions.

- UBP2 is a model-based approach for efficient preference-based reinforcement learning
- It uses ensembles of reward, dynamics, and value function models to evaluate uncertainties
- UBP2 actively directs exploration by jointly reasoning over uncertainties
- The method aims to improve sample efficiency in preference-based RL
- UBP2 has the potential to enhance the field of RL by providing a more efficient method for learning from preferences
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.
