of the exact step in the algorithm performed better than the rest so you see the first one is about the mix and match where it's 100 mix and match and it gave an error rate of 11 for 250 labels and an error rate of six percent which is quite good for 4000 labels they removed the distribution averaging or the guess labels and said the number of transformations as one it gave in a 17 error rate again no sharpening it given 27 they had an um they do mix up they did it with label data mixer they did it with unlabeled
