摘要: 该文在交易数据库和最小支持度不变条件下,当用户动态地增加或删除交易项目集中的某些交易项目时,充分利用了交易项目集改变前已采掘出的频繁模式集,提出了两种关联规则的快速更新算法Izi-ar和Dzi-ar。经实验分析表明,该算法用于关联规则的更新是可行的和高效的。

Abstract: In this paper,when user increases or decreases some transaction items from the transaction item set,fast updating algorithms Izi-ar and Dzi-ar of mining association rules,that fully uses frequent pattern sets of association rules mined,arc presented in the transaction database DB and the minimum support confidence.Through experiment discussing,the updating algorithms arc corrective and fast.
