Detect Outliers Using Isolation Forest

The Isolation Forest (IForest) algorithm is a powerful and scalable algorithm for identifying outliers in your data. It uses a unique approach which focuses directly on characterizing outliers instead of normal data points. Specifically, IForest focuses on the two quantitative properties of outliers: they are few and different. A scalable implementation of the Isolation Forest algorithm is available...
