Ensemble Isolation Forest

Ensemble Isolation Forest trenira višestruke Isolation Forest modele — svaki s različitim slučajevnim sjemenom (random seed), omjerom poduzorkovanja (subsampling ratio) ili parametrima kontaminacije — te kombinira njihove rezultate anomalije (anomaly scores) kako bi se dobilo stabilnije, robusnije rangiranje anomalija. Prosječnim zbrajanjem ili agregacijom više neovisnih stabala izolacije (isolation forests), metoda smanjuje varijancu svojstvenu bilo kojem pojedinačnom stablu i daje pouzdanije otkrivanje odstupanja (outlier detection) na složenim ili visokodimenzionalnim podacima.
