that and that's how you go but they're actually the other types of algorithms which are quite successful in text compression which we actually all use like in gzip and zip and so on which learn online so they they don't you don't really pre train them on a certain data set they just just give it a file and it learns how to compress it online and it turns out that maybe theoretically these types of algorithms at least if you get them lots of resources can actually learn to compress any distribution so we call them
