Example ROC and threshold-accuracy curves. A) Plot of true classification rate vs. threshold distance for a 24D MPSS based on Dali and SMACOF. The maximum, corresponding to the intersection of the ROC curve and the iso-performance tangent, is marked in red. B) ROC curve for the same set of MPSS distances. The point associated with the best threshold from A) is indicated by the red circle.
