Abstract

ROC curves have been used for a fair comparison of machinelearning algorithms since the late 90's. Accordingly,the area under the ROC curve (AUC) is nowadays considereda relevant learning criterion, accommodating imbalanceddata, misclassification costs and noisy data.This paper shows how a genetic algorithm-based optimizationof the AUC criterion can be exploited for impactstudies and sensitivity analysis.The approach is illustrated on the Atherosclerosis Identificationproblem, PKDD 2002 Challenge.
