ROC Curves comparing classifier performance on individual organisms. For each ROC curve, the classifiers were trained on five of the organisms and then evaluated on the sixth organism (given in the title). The solid (Ensemble*), dashed (GPCRHMM*), and dotted (Pfam*) lines represent the relationship between the percentage of correctly predicted training set GPCRs (true positives) and the percentage of incorrectly predicted non-GPCRS (false positives) as the likelihood score threshold is decreased from 1 (accept nothing) to 0 (accept everything). GPCRHMM (diamond), Pfam (circle), and PredCouple (square) only produce true/false predictions for each sequence and hence are represented as single points.
