arXiv:2606.11982v1 Announce Type: new Abstract: Preference-based reinforcement learning (PbRL) learns policies from human trajectory-level comparisons, avoiding explicit reward design and expert demonstrations. Existing methods typically train utility functions on trajectory or segment-level preferences while relying on per-step utility estimates during policy optimization. This training and inference mismatch induces a distribution shift that severely degrades temporal credit assignment and limits policy learning. We analyze this issue and propose PAWS, a segment-based preference learning met
The rapid advancement in AI necessitates more robust and efficient methods for preference learning, especially as systems become more autonomous and interactive.
Improving preference-based reinforcement learning directly enhances the ability of AI systems to learn complex tasks from human feedback, reducing reliance on explicit reward engineering.
This research introduces a novel approach to overcome key limitations in current preference learning methods, potentially leading to more reliable and generalizable AI training.
