The Isolation Forest algorithm is related to the well-known Random Forest algorithm, and may be considered its unsupervised counterpart. The idea behind the algorithm is that it is easier to separate an outlier from the rest of the data, than to do the same with a point that is in the center of a cluster (and thus an inlier).
