| 摘 要： | 给出了时间序列的变化序列和最近时间子序列的概念．并把最近时间子序列看作是时间序列的信息聚集器。基于这一现点,提出了基于变化序列的时序数据挖掘技术。先把待挖掘的时间序列转换成时间序列的变化序列,然后利用时间序列的变化序列的最近时间子序列隐含的知识,以指导对原时间序列的挖掘,并给出了挖掘算法。最后算例验证了该挖掘方法的可行性和有效性。

| Abstract: | The time series varying series and the latest time sub-series are defined.The latest time sub- series is regarded as the information collector of the time series.Based on the concept,the time series da- ta mining technique based on time series varying series is presented.Firstly the time series set for min- ing is converted into its varying series set,and then the information underlying in the latest time sub-se- ries of the time series varying series is used as a guide to excavate the original time series.And mining algorithms are given.Finally,a concrete mining example proves that the method is feasible and effec- tive. |
