Another problem with ROC AUC is that reducing the ROC Curve to a single number ignores the fact that it is about the tradeoffs between the different systems or performance points plotted and not the performance of an individual system, as well as ignoring the possibility of concavity repair, so that related … Visa mer A receiver operating characteristic curve, or ROC curve, is a graphical plot that illustrates the diagnostic ability of a binary classifier system as its discrimination threshold is varied. The method was originally developed … Visa mer The contingency table can derive several evaluation "metrics" (see infobox). To draw a ROC curve, only the true positive rate (TPR) and false positive rate (FPR) are needed (as functions … Visa mer In binary classification, the class prediction for each instance is often made based on a continuous random variable $${\displaystyle X}$$, which is a "score" computed for the instance (e.g. the estimated probability in logistic regression). Given a … Visa mer If a standard score is applied to the ROC curve, the curve will be transformed into a straight line.
