know goes on in little little steps one by one that keeps it in the realm of rather having to like it's easier to learn a good representation than it is to collapse to that to that solution okay so again components is image then you ought meant differently then you run it through different encoders but the encoders are similar in the fact that one is the exponential moving average of the other and then you try to predict one from the other and that ultimately makes the representation be independent of the augmentation and that means that
