Improving iforest with relative mass
WitrynaIn this paper, we propose a very simple but effective solution to overcome this limitation by replacing the global ranking measure based on path length with a local ranking measure based on relative mass that takes local data distribution into consideration. Witryna31 gru 2013 · We demonstrate the utility of relative mass by improving the task specific performance of iForest in anomaly detection and information retrieval tasks. History …
