Weakness: 1. Some details of the proposed method are missing, such as the definition of \mathcal{L}{{kl} and the representation of the augmentation samples in the function. 2. In the proposed method, a novel augmentation strategy is proposed with mask. In the ablation study, the effectiveness of the proposed strategy has not been verified by comparing with mixup and so on. The main contributions of the proposed method should be further verified in the experiments. 3. Meanwhile, more details about the proposed method should be presented, such as how the implicit distribution characterize the uncertainty of each label value and how the model mitigrate the uncertainty of the label distribution.
