摘要 为了提高效率,基于时间序列的数据挖掘,采用了近似的方法取代原有时间序列,这导致了数据挖掘准确性的降低,文章的主要目标在于有效率地搜寻时间序列中的相似子序列向量,且希望能够兼顾准确性及效率,进而提供不同领域对于时间序列的不同需要. Based on the data mining of times series,the approximation-like methods for performance improvement,lead to decrease of accuracy.In this paper,we focus on the efficient method of searching similar subpattern,which considers balance between performance and accuracy.
