[Pytorch] spatial dropout的实现 ... dropout是神经网络中一种常用的正则化技术，其通过随机失活神经元元素，降低单元之间的相互依赖关系，从而降低过拟合 ...

19.07.2018 · In both Keras and PyTorch after applying embedding on [batch, time] sequence you get [batch, time, channels] tensor. Keras’ SpatialDropout1D applies [*, 1, *]noise mask - i.e. drops out a subset of channels for all timestamps simultaneously, whereas PyTorch’s Dropout*D uses [*, *, 1]mask - it drops out all channels for a subset of timestamps.

Dropout. During training, randomly zeroes some of the elements of the input tensor with probability p using samples from a Bernoulli distribution. Each channel will be zeroed out independently on every forward call. This has proven to be an effective technique for regularization and preventing the co-adaptation of neurons as described in the ...

Nov 22, 2018 · Dropout is designed to be only applied during training, so when doing predictions or evaluation of the model you want dropout to be turned off. The dropout module nn.Dropout conveniently handles this and shuts dropout off as soon as your model enters evaluation mode, while the functional dropout does not care about the evaluation / prediction mode.

I cracked the case. I realized that I flip model.train() to model.eval() in the test call without setting it back to train() after.
