| 摘 要： | 针对在线增量部分周期模式挖掘中计算复杂度过高的问题,提出了一种带移动时间窗的时间序列部分周期模式挖掘算法.在时间序列的数据挖掘过程中,某些应用场合只要求对近期的时间序列数据进行挖掘发现部分周期模式,作为时间序列未来行为趋势的预测.因此在挖掘过程中,利用时间窗口,在先前挖掘结果的基础上,对最近的时间序列进行部分周期模式挖...

| Abstract: | In order to solve the problem of high complexity in the computation of the on-line incremental partial periodic pattern mining,this paper presented mining technology from a time series database based on a moving-window.In the process of data mining in time series,in some scenarios,it is only necessary to mine the partial periodic patterns in the recent time series databases in order to forecast the future action trend in time series.Therefore,during the mining,it needs to mine the partial periodic patterns ... |
