Witrynaproposed which measures relative density rather than absolute density. This improves the ability to detect local scattered anomalies. However, the ability to detect clustered anomalies is still limited by LOF’s underlying algorithm—k nearest neighbours, in which k has to be larger than the size of the largest anomaly cluster.

Witryna8 lut 2024 · In order to make iForest more sensitive to local anomalies, Aryal proposes to use a local ranking measure based on relative mass to replace the global ranking measure [ 8 ]. SCiForest can randomly generate cutting planes of various angles, which is suitable for more complex anomalies, but it has higher computational complexity [ 9 ]. Witrynamass in ReMass-iForest is a ratio of data masses between two regions covering the instances. The disadvantage of this method is that it increases computational …
