Chapter cover Improving iForest with Relative Mass - Springer
Witryna14 cze 2024 · Deep Isolation Forest for Anomaly Detection. Isolation forest (iForest) has been emerging as arguably the most popular anomaly detector in recent years … WitrynaThe new ranking scheme based on relative mass provides such a guarantee. The contributions of this paper are as follows: 1. Introduce relative mass as a ranking measure. 2. Propose ways to apply relative mass, instead of path length (which is a proxy to mass) to overcome the weaknesses of iForest in AD and IR. 3. chip blower
