| 摘要: |
| 孤立点挖掘是一个重要的知识发现任务,在介绍孤立点及其挖掘算法的基础上,利用孤立点检测方法对教务管理系统中积累的数据进行分析,并提出基于距离和的孤立点检测算法。实验结果分析表明,该算法降低了检测过程对用户设置阀值的要求,在时间复杂度上,稍微优于循环-嵌套算法。 |

| Abstract: |
| Outlier Mining is an important task in knowledge discovery. The knowledge of outlier and the algorithms for detecting outliers are introduced An algorithm based on distance sum is proposed. The test result shows that the algorithm presented can reduce requirements of thresholds to users in the detection. This algorithm is a bit better than the nested-loop algorithm in the time consumption. |
