摘要
针对关联规则挖掘问题提出一种新的算法,探讨商品与利润间的关系,称为权重式多重支持度关联规则挖掘算法。此算法可针对不同利润的商品定出不同的支持度阈值,由此产生的关联规则,可以解决高单价但交易次数稀少的商品不易被挖掘的问题。
In this article, we present an algorithm for association rules, call the Weight Algorithm with Multiple Supports for Mining Association Rules, is proposed to probe the relationship between itemsets and profit. It can set different supportive thresholds in accordance with different profit of itemsets. The related rule which was generated by WMMS algorithm can solve the problem that itemsets with high price but few trading times was difficult to find out.
