Prompt Sensitivity or Evaluation Artifact? A Task-Aware Analysis for Large Language Models

Prompt sensitivity is widely treated as a model robustness deficiency. Yet the extent to which measured sensitivity reflects genuine model instability, rather than artifacts of the evaluation method used to measure it, remains largely underexplored. We introduce Evaluation-Attributable Sensitivity (EAS), a per-instance...

Structure over Depth: A Single-Block Spatio-Temporal Transformer for Multi-Entity Reasoning

This work decomposes multi-entity temporal dynamics into three interaction types: spatial interactions among entities, temporal interactions across time, and cross interactions coupling the two domains, and proposes a structured spatio-temporal transformer block that explicitly models all three within a single stage.
