This is firstly appeared in 2012 arXiv with over 5000… Dropout: A Simple Way to Prevent Neural Networks from Overfitting So the training is stopped early to prevent the model from overfitting. The different networks will overfit in different ways, so the net effect of dropout will be to reduce overfitting. We present 3 new alternative methods for performing dropout on a deep neural network which improves the effectiveness of the dropout method over the same training period. Is the role of the validation set in a deep learning network is only for Early Stopping? With these bigger networks, we can accomplish better prediction exactness.
