CAUSALLY ROBUST REWARD LEARNING FROM REASON-AUGMENTED PREFERENCE FEEDBACK
Leveraging Language Rationales for Robust AI Reward Learning
This research introduces ReCouPLe, a novel framework designed to enhance the robustness and transferability of AI reward learning by integrating natural language rationales with preference feedback. Traditional preference-based reward learning is prone to causal confusion, where models latch onto spurious correlations instead of true causal features. ReCouPLe mitigates this by treating rationales as guiding projection axes in an embedding space, training the model to align with causal features and generalize across tasks, even under distribution shifts.

🤖 Case Study: Robotic Arm Manipulation
In a simulated robotic arm task to pick up a box, traditional reward models (BT-Multi) struggled when the size-color correlation was flipped (e.g., large red box in training vs. large blue box in test). ReCouPLe, leveraging rationales like 'because it picks up a larger box', successfully identified the causal feature (size) and maintained high accuracy (0.960) even under such distribution shifts. This demonstrates its ability to prevent causal confusion and generalize effectively.
