about using this trick is that you need to keep in mind that there are now three different categories of models that shouldn't be directly compared to each other there are those models that are trained entirely without labels there are models that are class conditional and there are models that are not class conditional but that benefited from the use of labels to guide the training somewhat and it wouldn't really be fair to make a class conditional model and then say that it's strictly superior to some model that didn't use labels to
