Detailed Description

template<class TModel>
class otb::SVMCrossValidationCostFunction< TModel >

This function returns the cross validation accuracy of a SVM model.

It allows performing parameters selection to maximize the accuracy using ITK optimizers.

Given an input SVM model, the number of parameters depends on the type of kernel:

Please note that this function is only defined on $ R_{+}^{*} $.

The GetDerivative() uses the GetValue() function to compute the partial derivatives. as such, it can be quite intensive.
