Classification accuracy of RF and SourceTracker using different sets of input features. On the left side of each plot is the RF classification accuracy with sets of 10 to 200 of the top-ranked features according to information gain (A), chi-square (B), and RF feature permutation (C) criteria. The right-hand side of each plot shows Source Tracker’s classification accuracy with all features. The four types of input features used were OTUs only (orange markers); OTUs and clades (green markers); functional predictions made using PICRUSt (purple markers); and all generated features (blue markers).
