This is a lightweight and versatile robustness benchmark built upon the training set of ImageNet-1K. It contains an overall of 50,000 images, divided in 5 components, evenly distributed over 1,000 classes. It assesses the performance of a classification model in five aspects: accuracy on intrinsically difficult images (SuperHard, SH), images with partial information (PartialInfo, PI), robustness against low resolution (LowResolution, LR), adversarial attacks (AdversarialAttack, AA), and speckle noise (SpeckleNoise, SN).
