- skfda.preprocessing.smoothing.validation.akaike_information_criterion(hat_matrix)[source]#
Akaike’s information criterion for cross validation.
\[\Xi(\nu,n) = \exp\left(2 * \frac{tr(\hat{H}^\nu)}{n}\right)\]See [1] for additional details.
- Parameters:
hat_matrix (ndarray[Any, dtype[float64]]) – Smoothing matrix whose penalization score is desired.
- Returns:
Penalization given by the Akaike’s information criterion.
- Return type:
