Outlier detection based on random forest

Abstract

摘要: 提出一种基于随机森林方法的异常样本 (outliers)检测方法。仿真实验表明 ,与其他 2种基于 距离的异常样本检测技术相比 ,这种方法可以更好地提高模型的准确率 ,且具有较强的鲁棒性 ,在处 理大规模数据集时还能显著地减少计算时间。Abstract: It intr oduces an outliers detecti on method based on random forest . Compared with the other t wo common outliers detecti on methods based on distance, the p roposed method can i mp r ove the performance and robustness of the model and can als o reduce the computati on ti me
