| 摘 要： | 序列相似性模式搜索是营销数据仓库中知识发现领域的一个研究热点。本文利用小波工具提出了一个基于Hurst指数的序列相似性判别标准和算法,新方法在某一分辨率层次上进行曲线形状的相似性搜索和度量,从而可以提高营销相似性模式查询的效率。最后用算例对方法的有效性加以验证。

| Abstract: | The similarity pattern query about time series is one of the research hotspots in knowledge discovering in the marketing database.Based on varying-time index,new discrimination standard and algorithm of series similarity are introduced.The similarity of curve in basic figure is queried and measured at some resolution ratio level,in the meantime,the fractal dimension in local similarity is matched.The effectiveness of the method is validated by means of the simulation example in the end. |
