This is firstly appeared in 2012 arXiv with over 5000… more nodes, may be required when using dropout. 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. Dropout, on the other hand, modify the network itself. 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.
