/ Activation function

Calculates the derivative tanh(x) (Tangent Hyperbolic Function).

tanh(x) function is used in the activation function of the neural network.


x

$<br />\normal Tangent\ hyperbolic\ function\ \tanh(x)\\[10]<br />f(x) = \large \tanh(x) = \large \frac {e^{x}-e^{-x}}{e^{x}+e^{-x}}\\[15]<br />\normal f'(x) = 1 - f(x)^{2} \\[15]<br />\normal f''(x) = - 2 f(x) \left{ 1 - f(x)^{2} \right} \\[15]$
