【摘要】 文章研究了在大型事务数据库中挖掘加权关联规则的问题,给出了加权频繁模式树的定义,在挖掘算法MIN-WAL(O)和MINWAL(W)的基础上,提出了一种基于加权频繁模式树的加权关联规则挖掘算法-WFPTA,并做了相应的算法比较,试验结果表明算法WFPTA是有效的。更多还原

【Abstract】 This paper discusses the problem of discovering weighted association rules between item in a large database of sales transaction,and a new algorithm is provided based on the algorithms of MINWAL(O)and MINWAL(W).Com-paring with other algorithms ,the author also offers some experiments to show that the new algorithm is more efficient.更多还原
