Validation. (a) False positive rate (FPR, x-axis) versus true positive rate (TPR, y-axis) of TaxMapper results on test dataset (blue), TaxMapper result on holdout data (orange), and simple E-value cutoff results on test dataset (red). (The blue and orange curves overlap in the subfigure on the left side.) The green background indicates the desired area with a low FPR (≤0.1). (b) Accuracy of TaxMapper on the random nonsense data (green) against the probability cutoff. (c) False positive rate of TaxMapper on the random data over all probability cutoffs
