void sgpp::datadriven::OperationTestPoly::calculateROCcurve ( sgpp::base::DataVector alpha,
sgpp::base::DataMatrix data,
sgpp::base::DataVector classes,
sgpp::base::DataVector thresholds,
sgpp::base::DataMatrix ROC_curve 
)
virtual

Computes the classification accuracy on some test data.

The function is evaluated at the given points. Tests on the classes {+1, -1}, cut-off variable at threshold

Also the number of the TP TN FP FN are determined

Parameters
alphathe coefficients of the sparse grid's base functions
datathe coordinates of the evaluation points
classessgpp::base::DataVector the holds the class information
thresholdsthe thresholds (between -1.0 and 1.0) for calculating the ROC curve
ROC_curveDataMatrix into which the ROC curve is stored
