Decision tree model An example of a decision tree model for the genomic island classification of Streptcoccus. Each interior node is one of the features (i.e.,Density, Insertion point, Integrase, IVOM, and Repeat), while each leaf node is the classification (i.e., “Yes” indicates the test sequence segment is GI, while “No” indicates it is a nonGI).
