| 摘 要： | 生成关联规则算法FAS，能够迅速区分某频繁项集的所有关联规则的前件和后件，生成给定频繁项目集的关联规则。基于FAS算法，设计并实现了一个基于最近挖掘结果的数据挖掘系统AR—Miner。该系统主要包括数据预处理、频繁集初始计算、频繁集更新计算、频繁集选择、关联规则生成五部分，不仅实现了关联规则挖掘的可视化和生成结果按“支持度一可信度”形式的可视化，还为基于频繁集的交互式挖掘提供了方便、友好的界面。

| Abstract: | An association rules mining alogorithm FAS was proposed . It rapidly distinguishes in a certain frequent itemset all the formers and the latters which were used to generate association rules. A FAS-based data mining system AR_Miner with the latest mining results were also designed. It consists of five parts: Data Preprocessing, Initial calculation of frequent itemsets, Update calculation of frequent itemsets, Choice of frequent itemsets and generation of association rules. It not only visualized generated results in support-confidence form, but also provided an easily accessible and user-friendly interface for interactive mining based on frequent itemsets. |
