Apriori算法[1]是一种最有影响的挖掘布尔关联规则频繁项集的算法。其核心是基于两阶段频集思想的递推算法。该关联规则在分类上属于单维、单层、布尔关联规则。在这里，所有支持度大于最小支持度的项集称为频繁项集，简称频集。-Apriori algorithm [1] is one of the most influential association rule mining algorithm Boolean frequent item sets. Its core is based on a two-stage frequency set recursive algorithm ideas. The association rules on classification is one-dimensional, single, Boolean association rules. Here, all support is greater than the minimum support itemset is called frequent item sets, referred to as the frequency set.generated in two phases to detect and plot. And algorithms have been widely applied to business, network security and other fields.
