Benchmarking Neural Network Robustness to Common Corruptions and Perturbations

This repository contains the datasets and some code for the paper Benchmarking Neural Network Robustness to Common Corruptions and Perturbations (ICLR 2019) by Dan Hendrycks and Thomas Dietterich.

Requires Python 3+ and PyTorch 0.3+. For evaluation, please download the data from the links below.

Tiny ImageNet-C has 200 classes with images of size 64x64, while ImageNet-C has all 1000 classes where each image is the standard size. For even quicker experimentation, there is CIFAR-10-C and CIFAR-100-C. Evaluation using the JPEGs above is strongly prefered to computing the corruptions in memory, so that evaluation is deterministic and consistent.

ImageNet-C Robustness with a ResNet-50 Backbone trained on ImageNet-1K and evaluated on 224x224x3 images.

Method	Reference	Standalone?	mCE	Clean Error
Assemble-ResNet50	Lee et al.	No	56.5%	17.90%
AugMix	Hendrycks and Mu et al. (ICLR 2020)	Yes	65.3%	22.47%
Speckle	Rusak et al.	Yes	68%	24.2%
Stylized ImageNet	Geirhos et al. (ICLR 2019)	Yes	69.3%	25.41%
Patch Uniform	Lopes et al.	Yes	74.3%	24.5%
ResNet-50 Baseline		N/A	76.7%	23.85%

"Standalone" indicates whether the method is a combination of techniques or a standalone/single method. Combining methods and proposing standalone methods are both valuable but not necessarily commensurable.

Be sure to check each paper for results on all 15 corruptions, as some of these techniques improve robustness on all corruptions, and some methods help on some corruptions and hurt on others. Other backbones can obtain better results. For example, a vanilla ResNeXt-101 has an mCE of 62.2%. Note Lopes et al. have a ResNet-50 backbone with an mCE of 80.6, so their improvement is larger than what is immediately suggested by the table.
