Background:

Self-Supervised Out-of-Distribution Detection

Shifts in the data distribution may compromise the performance of deep learning methods. As these shifts are often unknown, methods from self-supervised learning can help identify feature clusters on the original and augmented data for more robust out of distribution detection. The work of [1] claims to successfully detect OOD data in unlabeled medical imaging datasets compared to other self-supervised, contrastive learning approaches. These methods will be compared in a principled manner on data with simulated semantic and distribution shifts, real-world medical imaging data with domain shift, to determine their respective advantages and limitations.
