LinearAmplitudeFunction.post_processing(scaled_value)

Map the function value of the approximated $\hat{f}$ to $f$.

Parameters

scaled_value (float) – A function value from the Taylor expansion of $\hat{f}(x)$.

Return type

float

Returns

The scaled_value mapped back to the domain of $f$, by first inverting the transformation used for the Taylor approximation and then mapping back from $[0, 1]$ to the original domain.
