Using Lower-Bound Representations for Trajectory Similarity Learning

This work revisits trajectory similarity learning from a lower-bound representation perspective and proposes LB-TrajRep, a unified lower-bound representation framework independent of deep neural embeddings that is able to consistently outperform state-of-the-art neural trajectory embeddings across diverse distance meas...

Experience Memory Graph: One-Shot Error Correction for Agents

Experience Memory Graph is proposed, a framework that reformulates agent failure recovery as a graph matching problem and consistently outperforms state-of-the-art reflection baselines in success rate and average reward, while requiring no test-time trial-and-error.
