    • QUOTE: It trains 6 times faster than tanh. Output value will be zero when input value is less than zero. If input is greater than or equal to zero, output is equal to the input. When the input value is positive, derivative is 1, hence there will be no squeezing effect which occurs in the case of backpropagating errors from the sigmoid function.
