摘要
介绍了关联规则的采掘问题 ,采用逐渐增加项目集大小的迭代方法 ,具体给出了层次算法 ,最后给出减少数据库扫描次数的改进算法。
This paper introduces the problem of data mining association rules. We adopt the iterative method to enhance the size of item set gradually and describe the hierarchical arithmetic in detail. Finally, an improving arithmetic by releasing the times of scanning database is proposed.
