Adam coats as you who who helped prepare this handout a few years ago actually and a half ago did this interesting study right where he took all of the unsupervised feature learning algorithms of the day that you know that there's guys like us I guess debate as my averin better as your oven better weather and he took a bunch of these algorithms and ran all of them and they read the model size so for unsupervised feature learning all of us have a have a large amount of data right if you know you're doing if you're learning from unlabeled
