数据库中的优对关联关系的挖掘

Mining of Association Relations of Excellent Twain in Database

挖掘关联规则是数据挖掘的一个重要任务之一。一般的关联关系是单向的,但在某些研究与应用中,需要用到更强的关联关系。为此,提出了一种双向的关联关系,并描述了其独特的函数性质。最后,给出了挖掘这种关联关系对的算法。

Discovering association rules is one of the most important task in data mining.Generally speaking the associ-ation relation means one side.However,the stronger association relations are needed in some research and application.So,in this paper,one kind of binary association rules are proposed,and the special properties of this relation in func-tion are characterd.Finally,the algorithm of finding the binary assocition rules are also presented.
