calculateROCcurve()

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

pure 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

alpha	the coefficients of the sparse grid's base functions
data	the coordinates of the evaluation points
classes	sgpp::base::DataVector the holds the class information
thresholds	the thresholds (between -1.0 and 1.0) for calculating the ROC curve
ROC_curve	DataMatrix into which the ROC curve is stored
