Aligning Multimodal Patient Evidence with Biomedical Knowledge Graphs for Clinical LLMs

Jiawen Du, Arshan Ali Khan, Chenhao Zhang et al. · 2026

Clinical questions often depend on linking a patient's multimodal evidence to external biomedical knowledge, yet existing predictive systems rarely represent such links explicitly, so they can neither be traced to their evidence sources nor removed to measure their contributions. We present MM-KG (Multimodal Knowledge …

Conformal Prediction with Paraphrase-Aware Scoring for LLM Uncertainty Quantification

Jiayi Xin, Evan Qiang, Zihan Zhu et al. · 2026

Uncertainty quantification (UQ) for large language models (LLMs) aims to provide reliable measures of predictive confidence, yet current methods are often unstable under meaning-preserving perturbations. Semantically equivalent paraphrases can induce substantial variability in predictive confidence, even for methods wi …
