A new study published on arXiv investigates the presence and impact of nonrobust features in deep learning models used for biomedical image analysis. The research indicates that these nonrobust features, which are predictive but not easily interpretable and vulnerable to adversarial attacks, significantly boost in-distribution accuracy on tasks like MedMNIST classification. However, the study also found that models relying heavily on these features exhibit degraded performance when faced with distribution shifts, highlighting a trade-off between standard accuracy and out-of-distribution robustness in medical imaging applications.
