PIRL
**Pretext-Invariant Representation Learning (PIRL, pronounced as “pearl”)** learns invariant representations based on pretext tasks. PIRL is used with a commonly used pretext task that involves solving [jigsaw](https://paperswithcode.com/method/jigsaw) puzzles. Specifically, PIRL constructs image representations that are similar to the representation of transformed versions of the same image and different from the representations of other images.
