【摘要】 针对动态的关联规则挖掘中阈值的合理设置问题,提出了一种阈值协调算法(TCA算法),以克服传统的主观经验设置阈值的局限。通过设计一个用于处理动态关联规则挖掘过程中矛盾规则的阈值协调器,以计算矛盾域为基础,动态调节阈值,求得规则的一个基本的阈值区间,达到客观设置阈值的目的。给出了该方法的具体步骤,通过实验证明了该算法的有效性。更多还原

【Abstract】 Aiming at setting the rational threshold value in dynamic association rule mining,an algorithm(TCA algorithm) to correspond threshold value is presented so that the limitation which sets the threshold value subjectively in traditional way can be avoided.Designing a threshold value coordinator to treat with the contradiction rule in dynamic correlative rule mining,adjusting the threshold value dynamically based on the calculation of contradiction field,the fundamental threshold value interval to achieve the purpose of setting the threshold value objectively can be attained.The detailed steps is given and the validity through experiment is verified.更多还原
