Improving iforest with relative mass
Witryna6 maj 2024 · Relative scores such as Local Outlying Factor and mass ratio have been shown to be better scores than global scores in detecting anomalies. 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 … Witryna17 lut 2024 · iForest只适合检测全局异常点，不适合检测局部异常点，因此有人做了改进, 论文为Improving iForest with Relative Mass.
