Mlxtend (machine learning extensions) is a Python library of useful tools for the day-to-day data science tasks. 关联规则分析是数据挖掘中最活跃的研究方法之一,目的是在一个数据集中找到各项之间的关联关系,而这种关系并没有在数据中直接体现出来。各种关联规则分析算法从不同方面入手减少可能的搜索空间大小...

Apriori关联规则算法(Python代码) 1993年,Agrawal等人在首先提出关联规则概念,迄今已经差不多30年了,在各种算法层出不穷的今天,这算得上是老古董了,比很多人的年纪还大,往往是数据挖掘的入门算法,但深入研究的不多,尤其在风控领域,有着极其重要的应用潜力 2022-03-22 10:12:39 ...

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 ...
