- In this paper,a new kind of algorithms BFI-DMFI(Mining Maximum Frequent Itemsets) and BFI-DCFI(Mining Frequent Closed Itemsets) is proposed. 摘要 提出了基于频繁项集的最大频繁项集(BFI-DMFI)和频繁闭项集挖掘算法(BFI-DCFI)。
- In BFI-DCFI,in order to generate frequent closed itemsets,we can make use of mining maximum frequent itemsets from frequent itemsets which have equal support. BFI-DCFI算法则是通过挖掘所有支持度相等的频繁项集中的最大频繁项集组合生成频繁闭项集。
- maximal frequent closed itemsets 最大频繁闭项目集
- minimum frequent closed itemsets 最小频繁闭项目集
- minimum strong frequent closed itemsets 最小强频繁闭项目集
- frequent closed itemset 频繁闭项集
- frequent closed itemsets 频繁闭项集
- global frequent closed itemsets 全局频繁闭项目集
- Further, based upon the desirable properties of closed itemset lattices, a partition-based algorithm is developed, which proves to be highly efficient without information loss. 提出了一个基于划分的高效算法,在信息无损的前提下提高算法的效率。
