to the audio experiment where you trained all this and a lot of images and then you take just the rest net encoder out and you put a linear classifier on top of it and see how well it performs on an omission air classification which is also the standard test being used in previous self supervision methods though initially they were all attempt with Alex net and but but the baselines for rest net existed this table so we've already seen relative position we've seen by gal in synchronization and and jigsaw puzzles so all these methods when
