CSE算法:利用对频繁序列扩展来进行序列模式挖掘

CSE algorithm:a sequential pattern mining method by extending frequent sequences

序列模式挖掘是在多个有序事件序列中查找出现频率大于某个阈值的序列模式的数据挖掘方法 ,自从1995年序列模式挖掘的概念被提出以来 ,人们不断地对序列模式挖掘算法进行研究和改进 .本文介绍了一种新的序列模式挖掘方法—CSE算法及其具体实现方法 ,并对该算法性能做了初步的评价 .

The sequential pattern mining is a method that discovers all frequent sequential patterns from a sequence database.It was first introduced in 1995.Many studies and improvement methods have contributed to sequential pattern mining to make it more efficient.Here we will give a new method called CSE algorithm.The paper not only introduce how to realize the algorithm but also give its performance evaluation.
