The widely used algorithm in data mining ie, apriori algorithm is specifically considered for the extraction of the knowledge.Ch. Shobha RaniA. Aruna
如标题所述,这次我要扯的是 Apriori算法╮(╯_╰)╭ Introduction Apriori, a classic algorithm for learning association rules, is designed to operate on databases containing transactions, for instance, collections of items bought by customers or details of a website frequentation, which is different...
- 核心思想:Apriori算法的核心思想是利用已知的频繁项集生成新的候选项目集,然后使用支持度过滤掉不可能的项集,最终得到频繁项集。 - 基本步骤:扫描数据集并计算每个项集的支持度,保留支持度大于最小支持度的项集作为频繁项集,利用频繁项集生成新的候选项目集,再次扫描数据集并计算候选项目集的支持度,重复步骤2-...

GSP算法是序列模式挖掘算法。GSP算法也是Apriori类算法,在算法的过程中也会进行连接和剪枝操作,不过在剪枝判断的时候还加上了一些时间上的约束等条件。详细介绍链接 PreFixSpan PreFixSpan算法是另一个序列模式挖掘算法,在算法的过程中不会产生候选集,给定初始前缀模式,不断的通过后缀模式中的元素转到前缀模式中,而不断...
