Figure 3

The effect of cut-off values, ρ, in case of heterogeneous data (Compound standards data). The true positive rates (TPR) versus the predictive positive values (PPV) are plotted. The performances of four different methods, SWRM, SWRE, SWRME, and DISCO, are compared according to the thirteen different ρ values, (0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 0.93, 0.95, 0.97, 0.99). The maximum F1 scores are occurred at ρ = 0.9 for SW-based methods and ρ = 0.7 for DISCO.
