摘要: 离群数据挖掘(0utlier mining,简称离群挖掘)是数据挖掘的重要内容.该文针对时序 数据进行离群数据挖掘方法的研究,提出了离群指数的概念,在此基础上设计了时序数据离群数 据挖掘算法,并对某钢铁企业电力负荷时序数据进行离群数据挖掘,结果表明了算法的有效性.Abstract: Outlier mining is an important part of data mining. In this paper, the outlier mining method for time series data is investigated. Outlier index is proposed for outlier and an algorithm is developed for outlier mining. The time series data of the power load of a steel plant are used for outlier mining. The results show the effectiveness of the algorithm.
