Locating Failure in Multi-Page Visually Rich Document Understanding Systems: An Empirical Attribution

Lewei Xu, Yihao Ding, Zihan Xu +5

Multi-page visually rich document understanding (MP-VRDU) systems can fail when evidence is not faithfully represented, not selected, or not used correctly, yet final accuracy alon…

Disentangling Structure and Semantics: How Schema Representation Affects LLM-Based SQL Generation

Daniel Yitian Su, Sophie Yiran Su, Qiang Sun +2

LLM-based text-to-SQL pipelines read the database schema as text, which carries both structural cues (tables, keys, relationships) and semantic cues (table and column names); prior…

MonteRET: AI Agent Enhancing Multimodal LLMs with Multi-granularity Knowledge Retrieval for Chest CT Report Generation

Yi Lin, Yihao Ding, Elana Benishay +8

Automated chest CT report generation remains challenging because clinically faithful reporting requires both whole-volume understanding and accurate description of localized anatom…
