| 2026 | CURA: Clinical Uncertainty Risk Alignment for Language Model-Based Risk PredictionabstractClinical language models (LMs) are increasingly applied to support clinical risk prediction from free-text notes, yet their uncertainty estimates often remain poorly calibrated and clinically unreliable.In this work, we propose Clinical Uncertainty Risk Alignment (CURA), a framework that aligns clinical LM-based risk estimates and uncertainty with both individual error likelihoods and cohort-level ambiguities.CURA first fine-tunes domain-specific clinical LMs to obtain task-adapted patient embeddings, and then performs uncertainty fine-tuning of a multi-head classifier using a bi-level uncertainty objective.Specifically, an individuallevel calibration term aligns predictive uncertainty with each patient's likelihood of error, while a cohort-aware regularizer pulls risk estimates toward event rates in their local neighborhoods in the embedding space and places extra weight on ambiguous cohorts near the decision boundary.We further show that this cohort-aware term can be interpreted as a crossentropy loss with neighborhood-informed soft labels, providing a label-smoothing view of our method.Extensive experiments on MIMIC-IV clinical risk prediction tasks across various clinical LMs show that CURA consistently improves calibration metrics without substantially compromising discrimination.Further analysis illustrates that CURA reduces overconfident false reassurance and yields more trustworthy uncertainty estimates for downstream clinical decision support.

| 2025 | ChatGPT Comes to Campus: Unveiling Core Themes in AI Policies Across U.S. Universities with Large Language ModelsabstractThe release of popular generative artificial intelligence (AI) tools like ChatGPT have prompted universities to introduce new policies or update existing ones.Currently, most institutions adapt their policies reactively as challenges arise, often without adopting a systematic framework, with minimal guidance and limited knowledge of the approaches taken by other institutions across the United States (U.S.).This study aims to bridge this gap by identifying core themes surrounding AI policies and guidelines across the top 50 U.S. universities.Given the labor-and time-intensive nature required to manually synthesize multiple policy documents across many institutions, we leverage large language models (LLMs) to identify common and prevalent themes.Our framework first summarizes AI policies at the institutional level, followed by the generation of multiple sets of themes through an iterative process of prompt chaining and self-refinement.Finally, the common themes from these distinct sets were consolidated.This framework is designed to address potential flaws in pre-trained LLMs, such as hallucinations.Seven distinct themes are uncovered: (1) academic integrity and responsible AI use, (2) communication of AI policies, (3) data privacy and security concerns, (4) ethical considerations in AI use, (5) continuous adaptation and policy evolution, (6) documentation and transparency in AI usage, and (7) instructor discretion in AI integration.Our work lays the foundation for future analyses or recommendations in developing comprehensive and equitable AI policies.Furthermore, leveraging LLMs allows us to respond swiftly to developments surrounding AI policies across universities.
