In this paper we establish rigorous benchmarks for image classifier robustness. Our first benchmark, ImageNet-C, standardizes and expands the corruption robustness topic, while showing which classifiers are preferable in safety-critical applications. Then we propose a new dataset called ImageNet-P which enables researchers to benchmark a classifier's robustness to common perturbations. Unlike recent robustness research, this benchmark evaluates performance on common corruptions and perturbations not worst-case adversarial perturbations. We find that there are negligible changes in relative corruption robustness from AlexNet classifiers to ResNet classifiers. Afterward we discover ways to enhance corruption and perturbation robustness. We even find that a bypassed adversarial defense provides substantial common perturbation robustness. Together our benchmarks may aid future work toward networks that robustly generalize.

该文章为图像分类器的稳健性建立了严格的基准测试，并提出了两个基准测试 ImageNet-C 和 ImageNet-P，用于评估分类器对常见扰动和干扰的稳健性。研究发现，从 AlexNet 分类器到 ResNet 分类器，相对污染鲁棒性几乎没有变化，而绕过的对抗性防御提供了实质性的常见干扰强度。
