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.

"WitrynaBefore using the isolation forest in high-dimensional space for anomaly detection, the Auto-Regressive model is used first to predict the current data and calculate the confidence interval. Only the data not in the confidence interval needs to be detected. Secondly, a measure of the effectiveness of trees in the isolation forest is proposed. " - Improving iforest with relative mass
