RL for Medical Imaging: Benchmark vs. Clinical Performance

Published:Dec 28, 2025 21:57
1 min read
ArXiv

Analysis

This paper highlights a critical issue in applying Reinforcement Learning (RL) to medical imaging: optimization for benchmark performance can lead to a degradation in cross-dataset transferability and, consequently, clinical utility. The study, using a vision-language model called ChexReason, demonstrates that while RL improves performance on the training benchmark (CheXpert), it hurts performance on a different dataset (NIH).
