摘　　要：关联规则是数据挖掘中的重要研究内容之一,对在事务数据库不变,只对最小支持度和最小可信度进行改变的情况下,针对关联规则的维护问题,设计了一个增量式更新的改进算法AIUA。Finding association rules is an important part of data mining field. A kind of advanced incremental updating algorithm(AIUA) is presented for efficient maintenance problem of association that the minimum support and the minimum confidence changed but the transaction database maintained immutably. Finally, the paper gives out some experimental results to verify the high performance of AIUA.
