Dropout is typically interpreted as bagging a large number of models sharing parameters. We show that using dropout in a network can also be interpreted as a kind of data augmentation in the input space without domain knowledge. We present an approach to projecting the dropout noise within a ...
data augmentationiteratively reweighted least squareDropout and other feature noising schemes have shown promising results in controlling over-fitting by artificially corrupting the training data. Though extensive theoretical and empirical studies have been performed for generalized linear models, little work ...

并且,这篇论文提到的AlexNet网络模型引爆了神经网络应用热潮,并赢得了2012年图像识别大赛冠军,使得CNN成为图像分类上的核心算法模型。 随后,又有一些关于Dropout的文章《Dropout:A Simple Way to Prevent Neural Networks from Overfitting》、《Improving Neural Networks with Dropout》、《Dropout as data augmentation》。
《SUPERPOSITION AS DATA AUGMENTATION USING LSTM AND HMM IN SMALL TRAINING SETS》 链接:https://pan.baidu.com/s/1hMljmjUvC0e7TwZUB7oyTw 提取码:p9kk 摘要 考虑到音频和图像数据具有量子性(数据用密度矩阵表示),我们采用叠加增强的方法混合训练样本,在三层叠加的LSTM和HM...猜...
