【摘要】 关于多级关联规则挖掘方面的研究到目前为止还非常有限,尤其是在减少所需存储空间、产生有效规则、缩短计算时间方面还有很多工作要做。基于FP-Tree的算法在以上方面被证实有其非常大的优势。提出了一种基于FP-Tree的多级关联规则挖掘算法,并采用简化前缀树的方法优化算法性能。更多还原

【Abstract】 There is still a lot of work to do in Multilevel association rules mining,especially in how to reduce the storage space,produce more effective rules,improve algorithm performance.FP-Tree based algorithms are proved to be having great advantage in all these aspect.So this article introduce a FP-Tree based multilevel association rules mining algorithm,and a method reducing the space of prefix tree to improve the performance is used.更多还原
