Tanh as activation function
WebTanh– This activation function maps the input to a value between -1 and 1. It is similar to the sigmoid function in that it generates results that are centered on zero. ReLU– (Rectified Linear Unit): Transfers a negative input to zero and a positive input to itself. Because of its simplicity and efficacy, it is often employed in deep neural ... http://ufldl.stanford.edu/tutorial/supervised/MultiLayerNeuralNetworks/
