Witryna1 lis 2024 · Different from density or distance based measure, RMHSForest utilizes a novel relative mass estimation to improve the detection of local anomaly. Meanwhile, half‐space tree based on augmented... 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 ].
