data but you want to make sure that the unlabeled data is also influencing the classifier in some way so one simple idea is you take your classifier and ask ask you to predict on the unlabeled data and you want to make sure that the classifier is pretty confident on the unlabeled data or rather it's entropy of the class probabilities it outputs on the unlabeled data is small enough and this way you ensure that the structure is this way you ensure that the classifier is understanding the structure the unlabeled data we're
