[R] AugMix: A Simple Data Processing Method to Improve Robustness and Uncertainty

Paper: https://arxiv.org/pdf/1912.02781.pdf

Code: https://github.com/google-research/augmix

We propose AugMix, a data processing technique that mixes augmented images and enforces consistent embeddings of the augmented images, which results in increased robustness and improved uncertainty calibration. AugMix does not require tuning to work correctly, as with random cropping or CutOut, and thus enables plug-and-play data augmentation. AugMix significantly improves robustness and uncertainty measures on challenging image classification benchmarks, closing the gap between previous methods and the best possible performance by more than half in some cases. With AugMix, we obtain state-of-the-art on ImageNet-C, ImageNet-P and in uncertainty estimation when the train and test distribution do not match.
