Two new research papers explore the critical issue of uncertainty estimation in AI models used for clinical applications. The first paper introduces a novel Bayesian approach for large language models (LLMs) in clinical text classification, treating the LLM as a simulator to generate a posterior distribution over diagnoses. This method aims to provide more reliable uncertainty quantification than traditional black-box methods, demonstrating superior performance in distinguishing correct predictions from errors on clinical benchmarks. The second paper focuses on vision-language models used in clinical prediction, highlighting the importance of carefully selecting a "correctness criterion" for evaluating uncertainty estimation. It proposes a framework to assess these criteria based on human agreement and fidelity to downstream performance, finding that standard methods can distort results and even reverse the ranking of different uncertainty estimation techniques.
