摘要
将项目权值引入传统关联规则挖掘中是在项目属性上的扩展。本文分析项目权值对加权关联规则挖掘的影响,并对加权关联规则现有的算法进行总结,同时比较各算法的优缺点。最后对加权关联规则的未来研究发展方向进行探讨。
Introduce the item weights to traditional association rules mining is the expansion in the project properties.This paper analyzes the effects of the item weights to the weighted association rules mining, and the weighted association rules of existing algorithms are summarized and compared the advantages and disadvantages of them.Finally the research of the weighted association rules of the future development trend are discussed.
