摘要: 基于Apriori算法,研究了参数化模型间包含性关系,结合包含性关系在数据库中的隐藏形式,利用一种可以克服经典Apriori算法两个瓶颈的事务数据库构建方法,减少了扫描事务数据集的次数,并通过对频繁项集置信度的比对,输出了包含性关系的结果。以高中压阀门产品为数据对象,应用Weka数据挖掘软件的Explorer模块进行实例验证,输出了阀门各个参数化模型间的包含性关系。

Abstract: Based on Apriori algorithm, inclusion relations of parameterized models and their concealing database were studied. A method which might avoid the two performance bottlenecks of Apriori algorithm was used. This method may reduce the times of scanning database. The results of inclusion relations were output by comparing the confidence of frequent itemsets. Taking the data of high pressure valves as the target, the theory of inclusion relation was confirmed by the Explorer module of Weka and the inclusion relations of high pressure valves were output.

Key words: product platform, parameterized model, inclusion relation, transaction database
