We propose AdAutoMix, an adversarial automatic mixup augmentation approach that generates challenging samples to train a robust classifier for image classification, by alternatively optimizing the classifier and the mixup sample generator. AdAutoMix comprises two modules, a mixed example generator, and a target classifier. The mixed sample generator aims to produce hard mixed examples to challenge the target classifier while the target classifier’s aim is to learn robust features from hard mixed examples to improve generalization. To prevent the collapse of the inherent meanings of images, we further introduce an exponential moving average (EMA) teacher and cosine similarity to train AdAutoMix in an end-to-end way.

Mixed Images of Various Mixup-based Approaches.

🛠 Installation

💥News! ! !💥
2024-01-18: you can clone Openmixup training "AdAutoMix"[ICLR 2024].
2023-12-19: We update some analysis tools code such as: Calibration, FGSM calibration_fgsm.py and Occlusion Robustness occlusion_robustness.py experiments, also we support a mix augmentation method "SnapMix"[AAAI 2021].
Big thanks to Siyuan Li(@Lupin1998).

🔧How to install?🔧
In fact, you can add our python file in OpenMixup.
There, you can see how to use it and the environment required. What you need to do is add or replace our files by folder inside OpenMixup, and then add the function names of the files in the __init__.py file.
You also can download or find other Mixup methods in OpenMixup("https://github.com/Westlake-AI/openmixup")
Thanks contributors: Siyuan Li(@Lupin1998), Zichen Liu(@pon7) and Zedong Wang(@Jacky1128).
