Detection error tradeoff det curve
WebThe verification performance of biometric systems is normally evaluated using the receiver operating characteristic (ROC) or detection error trade-off (DET) curve. We propose … WebNov 1, 2016 · For rule-based systems, it can be described as the number of rules defining a classifier in proportion to the number of all possible rules. As it is easier to see the tradeoff between misclassification costs (i.e., fpr and fnr) when using DET space than when using ROC space, we use DET curve to describe the performance of binary classifiers.

WebA log-log plot is used to visualize the DET curve, which shows the tradeoff between FPR and FNR. The chart depicts the rate of false positive identification misses over the false positive range. A false negative in biometrics arises when an algorithm fails to match two samples of the same individual. WebNote.
