This seems quite large, and given the complexity of classification for Imagenet,it seems reasonable to want to make our dropout rate this high.
相反,单独使用Dropout方法不能防止参数值在训练阶段变得过大。
Dropout alone, instead, does not have any way to prevent parameter values from becoming too large during this update phase.
在本节,我简要地给出三种减轻过匹配的其他的方法:L1规范化、dropout和人工增加训练样本。
In this section I briefly describe three other approaches to reducing overfitting:L1 regularization, dropout, and artificially increasing the training set size.
他还解释了dropout是L2正则化的自适应形式,两种方法效果相近。
He also explains that dropout is nothing more than an adaptive form of L2 regularization and that both methods have similar effects.
Dropout layers first gained popularity through their use in CNNs, but have since been applied to other layers, including input embeddings or recurrent networks.
Several advanced layers such as dropout or batch normalization are also available as well as adaptive learning rates techniques such as Adadelta and Adam.
Dropout模拟来自给定层的稀疏激活,有趣的是,这反过来又鼓励网络实际学习稀疏表示作为副作用。
Dropout simulates a sparse activation from a given layer, which interestingly, in turn, encourages the network to actually learn a sparse representation as a side-effect.
We will use Lasagne to implement a couple of network architectures,talk about data augmentation, dropout, the importance of momentum, and pre-training.
Inverted Dropout should be using together with other normalization techniques that constrain the parameter values in order to simplify the learning rate selection procedure.
