Pretext-Invariant Representation Learning (PIRL)
Pretext-Invariant Representation Learning, also known as PIRL, is a method that is used to learn invariant representations based on pretext tasks. Essentially, PIRL is designed to create image representations that are similar to the representation of transformed versions of the same image, while being different from the representations of other images.
This technique is commonly used in a pretext task that involves solving jigsaw puzzles. By usi
