Figure 10: 5-fold cross-validation performance for species-accuracy on 9 species classes (77 strains), training on ∼ 62 strains and testing on ∼ 15 strains at a time. The maximum performance for each fragment size is 9 7 . 3 % ± 1 . 0 % for 500 bp, 9 5 . 3 % ± 1 . 3 % for 100 bp, and 9 0 . 2 % ± 1 . 2 % for 25 bp fragments, demonstrating that the NBC has good classification species accuracy for never seen before strains.
