WebMixup and its variants. Data augmentation has been widely studied to prevent DeepNets from over-fitting to the training data. To train and improve vision Transformer sta-bly, Mixup and CutMix are two of the most helpful augmen-tation methods [39]. Mixup [54] is a successful image mix-ture technique that obtains an augmented image by pixel- WebGenerally, CutMix is used as a data augmentation method in DL to expand training data size by producing more synthetic data. Here, it is used as a consistency-regularization-based method in the context of SSL by imposing perturbation on the unlabeled images and their predictions. The operation can be formulated as follows:
