关联规则中Apriori算法的研究与改进

Research and improvement on Apriori algorithm of association rules

Apriori算法是关联规则的一个重要算法。对关联规则挖掘算法Apriori算法的关键思想以及性能进行了研究,通过对候选项集的属性进行加权运算,减少了产生的频繁集,提高了算法的效率,使算法产生的规则更有应用价值。

Apfiori algorithm is an important algorithm of association rules.Based on the study of the principle and efficiency of the Apriori algorithm,this paper points out the defect and improve the method of produ- cing candidate set.The algorithm enhances the effi- ciency of the original one.
