When Correlations Mislead: Confounder-Aware Multi-View Urban Region Representation Learning

CURE is proposed, a confounder-aware framework for multi-view urban region representation learning that improves predictive performance, remains robust under missing and noisy input views, and provides reliable cross-view integration through shared component separation and context-dependent view weighting.

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...

Robustness Analysis of Agentic AI to Inconsistent and Incomplete Tool Responses

The results show that tool failures can be recognized at the return boundary, but reliable diagnosis requires combining multiple signals, and likelihood-based signals clearly capture incomplete returns and some direct inconsistencies, while action-based signals reveal how strongly a failure changes the next decision.
