Fig. 1.

The average AUC scores of the different machine learning methods and features. The averaged AUC scores are calculated by the average of the AUC scores across different hosts and different genome background distributions. The figures from top to bottom are the performances of different word lengths k=4, k=6 and k=8. The black segments on top of the bars are the standard deviation of the AUC scores across different hosts and different genome background distributions
