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 ].

While this is true, our analysis reveals for the first time that these relative scores have a key shortcoming: anomalies have greatly different relative scores if they are located in different regions …
