摘    要:关联规则挖掘的经典算法是Apriori算法,但是存在两大突出的问题,即多次扫描事务数据库和使用单一的支持度,导致了由于事务数据库的规模而增加搜索时间和产生冗余规则或有效规则被丢弃。以往的改进算法只从其中一方面进行考虑。因此同时考虑存在问题,给出了一种基于规模约简和多支持度的关联规则挖掘算法。分析和试验显示在效率上有提高。

关 键 词:数据挖掘  关联规则  经典算法  支持度  频繁集

Abstract:The classical algorithm for mining association rules is Apriori algorithm. But there are two problems in Apriori algorithm. They are scanning the database for many times and using single-support. Existing optimizing algorithms consider only one of the two problems and hence have their limitations. An algorithm for mining association rules based on reduced database and multi-support is given. Analysis and test show an improvement in efficiency.
Keywords:data mining  association rule  classical algorithm  support  frequent itemset
