Existing data augmentation in self-supervised learning, while diverse, fails to preserve the inherent structure of natural images.

We define augmentations in frequency space called Fourier Domain Augmentations (FDA) and show that training SSL models on a combination of these and image augmentations can improve the downstream classification accuracy by up to 1. 3% on ImageNet-1K.
