Cite What You Explore: Budget-Aware LLM Reasoning over Medical KGs with Verifiable Evidence

Post-discharge risk prediction from electronic health records (EHRs) is difficult because many dependencies that link discharge-time observations to downstream complications, such as comorbidity cascades and drug-disease interactions, are absent from the record. External medical knowledge graphs (KGs) can supply these...

RASPER: Reward-Aligned Summarization of Clinical Notes for EHR Outcome Prediction

Unstructured discharge notes in Electronic Health Records (EHRs) often carry signal complementary to structured medical codes, holding patient-specific evidence that standardized cohort-level codes alone cannot capture. However, this evidence in notes is frequently buried in lengthy, noisy text that is not intentionall...

MicrobeQuest: A Context-Aware Multimodal Benchmark for Microbiology Information Extraction

This work introduces MicrobeQuest, the first comprehensive multimodal benchmark for microbial information extraction tasks, comprising 11,877 expert-validated, context-aware query–response pairs, and formalizes microbiology-specific IE as a class of tasks that require structured data extraction, joint multimodal unders...

Hierarchical and Permutation-Invariant Feature Transformation Learning via Policy-Guided Embedding Search

This work proposes a framework with two complementary components: a permutation-invariant hierarchical module that captures interactions across features, operations, and abstraction levels, with a self-attention pooling mechanism that maps semantically equivalent structures to consistent embeddings aligned with downstr...

REFINE: LLM Refinement over Budgeted Text-Attributed Graphs for Personalized Medical Concept Representation

Learning rich medical concept representations is essential for EHR prediction. Text-attributed knowledge graphs (TKGs) provide a natural foundation by organizing heterogeneous medical relations together with textual semantics. However, most existing encoders process concepts uniformly across patients, despite the fact...
