CARE-X: A Chest X-Ray VLM with Auxiliary Supervision and Reward-Aligned Learning
CARE-X, a novel chest X-ray Vision-Language Model (VLM), integrates auxiliary discriminative supervision with reward-aligned generation to enhance diagnostic accuracy. By employing focal-loss classification and composite-loss grounding heads, the model allows for adjustable decision thresholds and improved spatial localization. This auxiliary supervision significantly boosts report quality, addressing the disparity between the requirements of radiologists and the capabilities of generative models. Researchers have made their findings available on arXiv under the identifier 2608.03890, contributing to advancements in AI technology in medical imaging.
