Precision-recall curves for intraspecies prediction (Case I). Precision v/s Recall observed by random forest are compared with that by each STRING scores, which score functional interactions based on genomic context. Random forest predictor achieves a higher recall compared to individual STRING scores for similar values of precision. The "combined score" provided by STRING is also shown to have high false positives in text for biophysical interactions. (A) represents the results for training and testing done with Mtb while (B) represents training and testing done with CD.
