Figure 3
Receiver operating characteristic (ROC) curve depiction of the results obtained on the test set using each of the three classifiers being assessed: support-vector machines (SVM, red), random forest (yellow) and k-nearest neighbours (KNN, turquoise). The horizontal and vertical axes correspond to the two operating characteristics, the false-positive rate and true-positive rate, respectively, measured at different confidence threshold values. A dashed diagonal line represents the performance of a no-skill classifier where predictions are made at random. |
