Function Documentation

template<class ScalarT>
inline ScalarT GridKit::Math::sigmoid(const ScalarT x)

Scaled sigmoid activation function.

Note

The sigmoid constant (mu) value is chosen to balance accuracy and finite derivatives. Large values more closely approximate a step function, but can make the transition numerically stiff.

Template Parameters:

ScalarT – - scalar data type

Parameters:

x – [in] - expected to be of order 1

Returns:

value of the sigmoid function
