Introduction Association rule mining is one of the most important techniques in data mining. consists of two main steps: frequent itemsets generation tries to extract the most frequent patterns; rule generation uses these frequent patterns to generate interesting rules. 3 林俊宏 ...
Section 5: The extensions of association mining needed for intuitionistic fuzzy sets are described, in particular the required set cardinality used for association rule generation. The running example extended to fuzzy intuitionistic data is then used to illustrate the approach using the various metrics...
一、基本概念 支持度:support(a→b)=P(ab) 置信度:confidence(a→b)=P(b|a)=P(ab)/P(a) 相关性:Lift(a→b)=P(ab)/P(a)P(b) 二、Aprior算法 *Partition:扫描两遍数据库 将数据分块,第一遍每块选出频繁集,第二遍找出全局频繁集。

In addition, this framework allows ad-hoc data mining queries over the whole data warehouse, not just over a transformed portion of the data that is required when a standard data-mining tool is used. Finally, this framework also expands the domain of association-rule mining from transaction-...
