I am implementing Isolation Forest from scratch, I am in dilemma of how to set contamination value, and what if not used im the code. Is accuracy differ? What other parameters required to run correctly.
I am using only 5 fold cross validation, then drawing forest, then computing tye amomaly scores and if <=0.5 then Normal otherwise Anomaly. Is it correct?
