Two Dropout Rates 图4 不同dropout概率组合的R-Drop,该表格是对称的,25个格子只有15种不同组合 默认两个分布用的dropout概率都一样,如IWSLT翻译用0.3,现在试训练时一个子模型用不同概率去dropout,从{0.1,0.2,0.3,0.4,0.5}{0.1,0.2,0.3,0.4,0.5}挑选概率值共15种设置(C52C52两两组合,C51C51两个...
dropout导致模型训练阶段和推理阶段不匹配,造成了gap。在训练中,通过dropout,其实是从完整模型中采样出一个子模型(sub models)来训练,但在推理中,是使用完整模型进行训练。 本文目的:解决dropout带来的训练/推理的不匹配问题。 1 mismatch问题究竟体现在哪 完整模型的测试误差由子模型的泛化误差,子模型的训练误差,完整...
首先看图-1,在每个mini-batch训练时,我们模型由于用了dropout,实际上变成了一个瘦小一点的模型,而我们forward两次的话,会得到对于相同输入X 的P1(y/x) 和 P2(y/x) 两个分布,R-drop这里呢会用 kl-散度 来约束这两个分布尽可能的一致,也就是对于相同输入,经过不同子模型,输出的结果分布要尽可能相似。接...

Dropout is a powerful and widely used technique to regularize the training of deep neural networks. Though effective and performing well, the randomness introduced by dropout causes unnegligible inconsistency between training and inference. In this paper, we introduce a simple consistency training ...
Dropout is a powerful and widely used technique to regularize the training of deep neural networks. In this paper, we introduce a simple regularization strategy upon dropout in model training, namely R-Drop, which forces the output distributions of different sub models generated by dropout to be...

We have deployed the \({L}_{2}\) norm regularization method for both the models (Model-1 and Model-2) to avoid the overfitting problem by fine-tuning the convolutional model parameters such as regulating the number of hidden layers, adjusting dropout rate, applying different learning rates, ...
近日,微软亚洲研究院与苏州大学在 Dropout 的基础上提出了进一步的正则方法:Regularized Dropout,简称R-Drop。与传统作用于神经元(Dropout)或者模型参数(DropConnect)上的约束方法不同,R-Drop 作用于模型的输出层,弥补了 Dropout 在训练和测试时的不一致性。简单来说就是在每个mini-batch中,每个数据样本过两次带有 Dro...
