Accelerating Diffusion Planners in Offline RL via Reward-Aware Consistency Trajectory Distillation

ICLR 2026poster

Although diffusion models have achieved strong results in decision-making tasks, their slow inference speed remains a key limitation. While consistency models offer a potential solution, existing applications to decision-making either struggle with suboptimal demonstrations under behavior cloning or…

Retrospective In-Context Learning for Temporal Credit Assignment with Large Language Models

NeurIPS 2025poster

Learning from self-sampled data and sparse environmental feedback remains a fundamental challenge in training self-evolving agents. Temporal credit assignment mitigates this issue by transforming sparse feedback into dense supervision signals. However, previous approaches typically depend on domain-…
