Figure 4

Learning curves (mean AUROC) with increasing number of target training examples. Error bars are 1 SE. When data availability is low, target-only training exhibits lower AUROC values and high variability. AUROC indicates area under the receiver operating characteristic; CV, cross-validation. The maximum mean AUROC achieved by the nested cross validation method is 0.8498.
