sigmoid function

The initial stage of deep learning is called sigmoid activation. The smoothing function can be derived with little effort as well. The Y-axes of sigmoidal curves are “S” shaped. The sigmoidal part of the tanh function expands the applicability of logistic functions to any “S”-form function (x). tanh(x) is not in the interval [0, 1], …
