【摘要】 针对最小支持度,最小置信度不变的情况下,新增数据库db时的关联规则更新问题,进行了分析和研究。考虑到新增数据库的新颖性、以及生成规则的有趣性等问题,本文提出了基于项目集加权的增量更新算法,并分析了其可行性。更多还原

【Abstract】 In this paper,we discuss the problem of updating the association rules when increasing the database without changing the minimum support and the minimum confidence.Furthermore,we propose a new method of incremental updating algorithm after the items are weighted in view of the novelty of the increments of database,which validation is also analyzed here.更多还原
