| 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. |
