today this is a predictive framework where it's it takes in a sequence and it tries to predict some subset of that sequence with a very simple linear model and you just have word of the same word event betting table we talked about but they both do about the same thing and they're kind of the canonical first round of distributed or scalable kind of unsupervised cell supervised representations for a multi again there's there's no you know human supervision classically involved in these algorithms they just kind of have
