一种改进的关联规则更新算法及其实现
Research and Implementation of an Improved Updating Algorithm for Mining Association Rules
【摘要】 论文研究了事务数据库记录增加时关联规则的更新问题。在FUP算法的基础上,引入候选支持度、次频繁项集和支持数上界等概念,据此提出了改进算法IFUP。
【Abstract】 The article introduces some research about association rules updating when the database records increase.Based on the FUP algorithm,the article proposes several conceptions including backup support threshold,minor frequent candidates set and upper bound of support count ,then presents an improved FUP algorithm IFUP.
