The invention relates to the technical field of network management and discloses an association rule mining method for an alarm event. Based on a branch screening optimization policy and an Apriori algorithm, the method comprises the steps of sequentially reading each event item in a database, ...
The association rule mining method specifically comprises the steps that input data are divided according to records, a frequent 1-itemset table is set, data projection is carried out on the frequent 1-itemset table, the projected data are stored in a set grouped table, a local frequent ...
当谈及购物篮分析和关联规则算法时,一则经典故事《啤酒与尿布》(它的真实性存在争议,有人认为是商业传奇,也有人认为是虚构的)常常被提及。这个故事以一家大型零售连锁店的数据分析为背景,引人入胜地揭示了消费者购物行为中的意外关联。故事中,分析师发现在某个城市的分店中,啤酒和尿布的销售量竟然时常同时增长。...

一、基本概念 支持度:support(a→b)=P(ab) 置信度:confidence(a→b)=P(b|a)=P(ab)/P(a) 相关性:Lift(a→b)=P(ab)/P(a)P(b) 二、Aprior算法 *Partition:扫描两遍数据库 将数据分块,第一遍每块选出频繁集,第二遍找出全局频繁集。
Frequent pattern mining 频繁项挖掘,代表算法FP-growth, 频繁项挖掘广泛的应用于寻找关联的事物。最经典的就是,电商企业通过分析用户的订单,挖掘出经常被共同购买的商品,用于推荐。 假设我们的Transaction数据库有5条交易数据,如下表,其中abcde为5个商品。假设设定minSupport = 0.4,即要求至少共同出现2次。
