1) closed items
封闭项目集
1.
Through found the closed items it can be dramatically reduced the number of frequent itemsets.
通过求封闭项目集大大消减了频繁项目集数量,再由封闭项目集构造一种新的存储机制———近似格,基于近似格可以得到冗余度较小的关联规则,从而提供用户简洁紧凑又无信息丢失的关联规则集。
2) quantitative closed itemset lattice
量化封闭项集格
1.
The minimum non-redundant rules with the minimal anteceadence and maximal consequence can be extracted from the quantitative closed itemset lattice,but such rules are not the minimum set satisfying the userspecified threshold.
从量化封闭项集格所提取的所有最小无冗余规则,虽满足最小前件最大后件的要求,但并不是满足用户设定支持度和置信度的最小规则集。
2.
For extracting rules conveniently, the quantitative closed itemset lattice is proposed with the modified node structure.
为便于规则的提取,提出了具有新的节点结构的量化封闭项集格。
4) φ frequent closed itemset
φ频繁闭项目集
5) frequent closed itemsets
频繁闭项目集
1.
New algorithm of mining frequent closed itemsets;
一种新的频繁闭项目集挖掘算法(英文)
2.
Discovering frequent closed itemsets is a key problem in data mining application.
在数据挖掘研究中,频繁闭项目集挖掘成为重要的研究方向。
6) frequent closed itemsets
频繁闭合项目集
1.
The set of frequent closed itemsets determines exactly the complete set of all frequent itemsets and is usually much smaller than the laster.
频繁闭合项目集集可惟一确定频繁项目集完全集且数量小得多,然而有关频繁闭合项目集的更新还不多见。
2.
There are many mining algorithms about frequent closed itemsets,such as CLOSET.
目前频繁闭合项目集挖掘算法有很多,例如CLOSET[1]。

〖ZK(〗各证集说诸方备用并五脏六腑集论合抄〖ZK)〗
内科著作。1卷。原题清叶桂(天士)家传，撰年不详。此书汇集内科杂证70余种，方剂近200首。每证各为一论，阐明疾病性质、病因、症状、治则及方药。论后每引经说，概括病机。所列方药服法亦皆详备。又列“五脏六腑论”一章，引用《内经》、《难经》，逐一论述五脏六腑之形象、部位、表里关系、病症及治法。本书内容多录自《临证指南》，恐系后人伪托叶氏之作。现存抄本
