一种新的多级模糊关联规则挖掘方法

A Novel Approach For Discovery Multi Level Fuzzy Association Rule Mining

Pratima Gautam, K. R. Pardasani

摘要:

在事务数据库中寻找多级关联规则是最常见的,在数据采掘中得到了广泛的应用。本文提出了一种挖掘多级关联规则的模型,该模型在每一级上满足不同的最小支持度,利用模糊集的概念、多级分类法和不同的最小支持度,在给定的事务数据集中发现模糊多级关联规则。模型中利用Apriori属性对项目集进行剪枝。该模型采用自上而下的逐步深化方法来获得大型项目集。这种方法采用模糊边界,而不是尖锐的边界区间。最后通过一个实例证明了该算法能够简单有效地挖掘出不同支持度下的多层关联规则。

英文摘要:

Finding multilevel association rules in transaction databases is most commonly seen in is widely used in data mining. In this paper, we present a model of mining multilevel association rules which satisfies the different minimum support at each level, we have employed fuzzy set concepts, multi-level taxonomy and different minimum supports to find fuzzy multilevel association rules in a given transaction data set. Apriori property is used in model to prune the item sets. The proposed model adopts a topdown progressively deepening approach to derive large itemsets. This approach incorporates fuzzy boundaries instead of sharp boundary intervals. An example is also given to demonstrate and support that the proposed mining algorithm can derive the multiple-level association rules under different supports in a simple and effective manner.
