Ensemble Isolation Forest

Ensemble Isolation Forest trenira višestruke Isolation Forest modele — svaki sa različitim slučajnim semenom (random seed), odnosom podsabiranja (subsampling ratio) ili parametrom kontaminacije (contamination parameter) — i kombinuje njihove rezultate anomalija (anomaly scores) radi dobijanja stabilnijeg, robusnijeg rangiranja anomalija. Averidžiranjem ili agregiranjem više nezavisnih isolation forest modela, ova metoda smanjuje varijansu inherentnu bilo kom pojedinačnom modelu i daje pouzdanije otkrivanje odstupanja (outlier detection) na složenim ili visokodimenzionalnim podacima.
