负关联规则挖掘算法的应用与研究

传统的正关联规则考虑的是事务中所列举的项目,而负关联规则不仅考虑事务中所包含的项,还考虑了数据库中存在而事务中所不包含的项。该文首先讨论了负关联规则的相关定义,以及它的支持度、置信度与相关度,并分析了PNARC模型的算法。最后对负关联规则的研究发展方向进行分析。

Application and Research of a Lgorithm for Mining Negative Association Rules

The tradition positive association rule mainly considering the listing project of the affairs, but the negative association rule is not only considered the items which in the listing affairs, but also including the items that are not listed in the listing affairs. This paper first discussed definition of the negative association rule, as well as its support, the confidence and the degree of correlation, and has analyzed the PNARC model algorithm. Finally carries on the analysis to negative connection rule's...
