WebMixup is a data augmentation technique that generates a weighted combination of random image pairs from the training data. Given two images and their ground truth labels: ( x i, y i), ( x j, y j), a synthetic training example ( x ^, y ^) is generated as: x ^ = λ x i + ( 1 − λ) x j y ^ = λ y i + ( 1 − λ) y j WebWe found that on both training sets, MixMatch nearly matches the fully-supervised\nperformance on the same training set almost immediately \u2013 for example, MixMatch achieves an error\nrate of 2.22% with only 250 labels on SVHN+Extra compared to the fully-supervised performance of\n1.71%. trentham rifle rangeWebMixUp augmented SSL method called MixMatch [15], and improve the previous state-of-the-art results, which suggests that our MetaMixUp is auxiliary to other methods of semi-supervised learning.
