Precision-recall plots showing the performance of both the support vector machine (SVM) predictor and the information theory approach for the test data (A) and the validation data (B). The scaled SVM outputs are shown for 0.1–0.9 on both plots, providing a more intuitive score from which to define a threshold for practical purposes (PPV, positive predicted value).
