| 摘 要： | 目前,已经有很多针对数据挖掘更新算法的研究,但大部分的更新算法都只是考虑事务数据库增量更新的情况.实际上,事务数据库数据还存在数据删减的更新问题,为了解决这类问题,提出了一种基于闭合序列模式的更新算法DeCloSpan,该算法对已有的挖掘结果直接进行删减更新,避免了重复挖掘.

| Abstract: | Now there are lots of researches on the updating algorithm of data mining.But most of them only aim at the situation of incremental updating algorithm of the transaction database,where exists the updating problem of data reduction.In order to solve this kind of problem,this paper presents an algorithm of DeCloSpan,which directly reduces and updates the mining results to avoid the mining repetition,based on closed sequential pattern. |
