[帮助文档] 机器学习线性支持向量机算法组件的配置及示例

支持向量机SVM（Support Vector Machine）是基于统计学习理论的一种机器学习方法，通过寻求结构风险最小化，提高学习机泛化能力，从而实现经验风险和置信范围最小化。本文介绍线性支持向量机算法组件的配置方法及使用示例。

机器学习关联分析PF和Apriori算法

1 什么是关联分析此篇为了解篇幅,不做具体的算法实例,就是知道简单有这么回事,什么情况会用到的分析.关联分析又称关联挖掘，就是在交易数据、关系数据或其他信息载体中，查找存在于项目集合或对象集合之间的频繁模式、关联、相关性或因果结构。或者说，关联分析是发现交易数据库中不同商品（项）之间的联系。简单的说...

②机器学习推荐算法之关联规则Apriori与FP-Growth算法详解

构建FP树第二步，扫描数据库，进行FP树的构建。FP树以root节点为起始，节点包含自身的item和count，以及父节点和子节点。首先是第一条交易数据，a b d，结合第一步商品顺序，排序后为b a d，依次在树中添加节点b，父节点为root，最新的的频次...

①机器学习推荐算法之关联规则Apriori与FP-Growth算法详解

Apriori算法介绍Apriori，中文是先验，开始的意思。这个算法为了规避前面说到的指数爆炸的问题，采取了提前剪枝的办法。核心是两条定律：定律一：如果一个集合是频繁项集，则它的所有子集都是频繁项集。定律二：如果一个集合不是频繁项集，则它的所有超集都不是频繁项集。Apriori定律举...
