Association rules mining is a very active field in data mining and there are many algorithms today. In this field, the most classical algorithm is Apriori put forward by Agrawal et. al and it is used widely. The paper analyzes the advantages an disadvantages of Apriori, AprioriTid and AprioriHybrid algorithm in mining association rules. To solve the bottle of AprioriHybrid algorithm, a Support-Matrix method to rapidly verify the 2-frequent itemsets is put forward. To accelerate the speed of verify the k-frequent itemsets, a simple and highly efficient method of minimizing the trade database is given. All these two methods improve the efficiency of AprioriHybrid method.
关联规则挖掘是数据挖掘中一个非常活跃的领域,当前有许多种算法,最经典并被广泛使用的是Agrawal等人提出的Apriori算法及其衍生算法,本文分析了Apriori,AprioriTid和AprioriHybrid算法的优缺点,针对AprioriHybrid算法的瓶颈提出一种使用支持度矩阵对频繁2项集快速验证的方法,并给出一种简单易行,而又高效的逐步缩减交易数据库的方法,加快对候选频繁k项集的验证速度,从而提高了AprioriHybrid算法的效率。

In short, the verification result shows the ability for mouse manipulation, the understanding of the association between the screen and the mouse among the 3 interviewees have gradually improved and enhanced via the "teaching material" training, in which case study A is successfully operated per course material instructions, while case study B, to even migrate the ability of mouse manipulation to other CAL software, it is evident that the practice of "teaching material" will help intellectual disabled students utilize CAL to open the ability for multiple-purpose learning, and to further enhance the learning outcomes.
验证结果发现经「中介教材」训练后,三位受测者在实验过程中对操作滑鼠之技能、对萤幕与滑鼠间之关联性的理解,均逐渐进步与提升,其中个案甲能在验证后期,依教材指示成功操作,而个案乙更能将操作滑鼠之能力迁移至其他CAL软体中,可见『中介教材』之练习有助於认知功能障碍学生运用电脑辅助学习,开启多元学习之能力,进而提高学习成效。

The results show that the KPW scheme is not a nominative signature scheme since the nominator not only can verify and prove the validity of given signatures but also can convert given signatures into universally verifiable signatures, and that the PL scheme is only a self-authentication signature scheme since anyone can verify the validity of given signatures.
摘要该文分别对一个指名签名方案和一个指名代理签名方案进行分析,结果表明:在KPW方案中签名人不仅能验证而且也能向第三方证明签名的有效性,甚至能将签名转化为通常的自认证签名,因此不是指名签名方案;在PL方案中任何人都可验证签名的有效性,它只是一个自认证签名方案。
