However, there are two drawbacks in mixup: one is that more training epochs are needed to obtain a well-trained model; the other is that mixup requires tuning a hyper-parameter to gain appropriate capacity but that is a difficult task. In order to solve the problem of the vanishing/exploding gradient, this architecture introduced the concept called Residual Network. Last active 13 months ago.
