direction and that lets you fool your classifier and you want to make sure that the in your classifier is not full if you for these perturbations and so you would perform at with stable training to make sure that the classifier is not full at these data in these different rotor patient directions now in Sammy squirrel learning you don't have the labels for unlabeled data so how would you address your training there so the idea is to do virtual address zero training where you look at the distribution of your classes instead
