基于时间索引的0-N数据结构在序列模式挖掘算法中的应用

摘要

在0-N数据结构的基础上结合时间索引,建立根据时间片段划分的序列数据块,通过对原始数据存储结构的改进达到减小扫描范围的目的,提高序列模式挖掘算法的效率.%On the basis of the 0-N data structure combined with the construct time index,set up the sequence data block according to the time slice,Through the change of the data structure of the original data to achieve the purpose of reducing the scanning range to improving the efficiency of sequential pattern mining.
