Interpretable Similarity of Synthetic Image Utility
Read the original on arXiv Computer Vision →The paper introduces Interpretable Utility Similarity (IUS), a novel metric for quantifying how closely a synthetic image set matches a real image set in terms of usefulness for deep‑learning clinical decision support systems. IUS is interpretable, leveraging generalized neural additive models to explain why one synthetic dataset may outperform another based on clinically relevant image features. Experiments on color medical imaging modalities—endoscopic, dermoscopic, and fundus—show that selecting synthetic images with high IUS can boost classification performance by up to 54.6%, and the method also generalizes to grayscale X‑ray and ultrasound data.
