Resolving the structural features of genomic islands: A machine learning approach

Radar diagram illustrating (A) the feature weight and (B) “importance” of the eight structural features under different GI models, based on 11 training data sets. Features: (IVOM) feature composition; (INSP) insertion point; (SIZE) the size of each region; (DENSITY) gene density; (REPEATS) repeats flanking each region; (INTEGRASE) integrase-like protein domains; (PHAGE) phage-related protein domains; (RNA) non-coding RNAs. Each apex in the octagon-like diagram corresponds to one of the eight structural features, while the height of the plot at the corresponding apex is indicative of the actual (A) feature weight or (B) importance.
