A well-known technique, association rule is implemented in this paper using Apriori algorithm in Python, to identify the most common item sets sold together, which further helps in figuring out the more beneficial shelf placement for better customer engagement. It was found that items having more...

1.如果一个项目集合不是频繁集合,那么任何包含它的项目(超集)也一定不是频繁集。 2.如果一个项目集合是频繁集合,那么它的任何非空子集(子集)也是频繁集合。 二、关联分析 1.发现频繁项集→ 经常出现在一起的样本集合 2.发现关联规则→ 暗示两种样本之间可能存在很强的关系 ...
