With the MNIST dataset, it is very easy to overfit the model. By dropping a unit out, we mean temporarily removing it from the network, along with all its incoming and outgoing connections, as shown in Figure 1. Abstract : Deep neural nets with a large number of parameters are very powerful machine learning systems. A higher number results in more elements being dropped during training. Dropout is a regularization technique for neural network models proposed by Srivastava, et al. If you [have] a deep neural net and it's not overfitting, you should probably be using a bigge A fast learning algorithm for deep belief nets.

At test time, it is easy to approximate the effect of averaging the predictions of all these thinned networks by simply using a single unthinned network that has smaller weights. Because the outputs of a layer under dropout are randomly subsampled, it has the effect of reducing the capacity or thinning the network during training. A modern recommendation for regularization is to use early stopping with dropout and a weight constraint.
