A new study published on arXiv investigates the generalization gap in dermatology AI models, specifically examining whether poor performance is due to underrepresentation of skin tones or shifts in disease distribution. Researchers evaluated several models, including ResNet-50, DermLIP, MONET, and DINOv3, on datasets designed to isolate these factors. The findings indicate that disease-distribution shift contributes more significantly to performance degradation than skin-tone underrepresentation in the tested scenarios. The study also highlights that representation quality predicts performance recovery with lightweight adaptation, suggesting that even a small number of labeled examples per category can significantly improve model accuracy.
