关联规则挖掘算法在教学管理上的应用

介绍了关联规则挖掘的基本概念,分析了经典的Apriori算法,提出一种改进的关联规则挖掘算法,在系统中永久保留支持度为0的候选1项集和候选2项集,当系统需要运行时,先采用数据库的过滤技术,可以很快得到频繁2项集。采用新算法在教学数据库中搜索所有的关联规则,从而得到课程与课程之间的关联关系,对教学管理具有一定的辅助决策意义。

Application of association rule mining algorithm in teaching management

This paper introduces the basic concept of association rule mining.Afler presenting the traditional Apriori algorithm,we introduce an improved association rule mining algorithm.The candidate 1-itemsets and candidate 2-itemsets whose support are 0 can be kept in the system for ever.When we do mining,we firstly adopt the technique of database filter,which can get the frequent 2-itemsets quickly.The new algorithm is used to search all association rules in the database and to get association relation between co...
