摘要
针对负序列模式挖掘的候选序列数量巨大的问题,在负序列模式算法PNSP的基础上提出了一种闭合负序列模式算法NPos D.经分析发现,NPos D算法能够挖掘出更加精简有效的负序列模式,算法是可行有效的.
In view of the huge data of the negative sequential patterns mining in candidate sequences,based on PNSP,an algorithm called NPos D is put forward in this paper. It is discovered that NPos D is feasible and effective because it can mine negative sequential patterns more compactly and effectively.
