ROC plot demonstrating the SVM performance for classifying host vs. phage psb A trusted sequences from GOS [11]based on genomic composition: mononucleotides (gray line), dinucleotides (green line), trinucleotides (blue line), tetranucleotides (red lines), all oligonucleotides (black lines). AUC (Area Under Curve) values are given in Table 1. As illustrated, best performance was achieved when including only the tetranucleotide composition.
