Figure 2From: Identification of novel arthropod vector G protein-coupled receptorsROC Curve comparing classifier performance on combined data set. The dashed (GPCRHMM*), dotted (Pfam*), and solid (Ensemble*) curves represent the relationship between the percentage of training set GPCRs correctly predicted (true positives) plotted against the percentage of sequences miss-classified as GPCRs (false positives) by the classifiers as the likelihood score threshold, was decreased from 1 (accepting nothing) to 0 (accepting everything). GPCRHMM (diamond), Pfam (circle), and PredCouple (square) only produce true/false predictions for each sequence and hence are represented as single points.Back to article page
