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. WebAxis warping. The normal deviate mapping (or normal quantile function, or inverse normal cumulative distribution) is given by the probit function, so that the horizontal axis is x = probit(P fa) and the vertical is y = probit(P fr), where P fa and P fr are the false-accept and false-reject rates.. The probit mapping maps probabilities from the unit interval [0,1], to …
