Classification quality for the phenotype periodontal disease causing. Left: classification of all genomes (266) into genomes related and not related to periodontal disease using the nearest neighbor classifier (IB1). Right: classification of oral genomes (15) into genomes related and not related to periodontal disease using the nearest neighbor classifier (IB1). Compared to classification based on all pathways (marked by a horizontal line) and based on randomly picked pathways (red), the classification based on the most relevant pathways yields better separation of periodontal species and other species in both genome datasets.
