Many real applications of outlier detection can be utilized in various fields. Most of such applications process high dimensional datasets. In one of our previous work, we proposed an Example-Based outlier detection method making use of outlier examples to detect outliers that have similar “outlier-ness” to these examples in high dimensional datasets. However, it employs meshes for deciding outliers, and all points within the same cell are regarded as normal objects or outliers. Thus, sometimes normal objects may be detected as outliers, and vice versa. Distance-Based outlier (DB-Outlier) detection is a simple and commonly used approach, besides it can detect real outliers by calculating the distance between data points. In this paper, we introduce a method to detect DB-Outliers in high dimensional datasets based on outlier examples, and show some comparison experiments between our new method and the old one. |
