WebIt is likely that humans are born with all of the nerve cells (neurons) that will serve them throughout life. For all practical purposes, when our neurons die, they are lost forever. During nervous system development, about one-and-a-half times the adult number of neurons are created. These "extra" neurons are then destroyed or commit suicide. WebAround 2^n (where n is the number of neurons in the architecture) slightly-unique neural networks are generated during the training process, and ensembled together to make predictions. A good dropout rate is between 0.1 to 0.5; 0.3 for RNNs, and 0.5 for CNNs. Use larger rates for bigger layers.
