Example of Naive Bayes Algorithm: In this tutorial, we will learn about the naive bayes algorithm with the help of an example.
生活中很多场合需要用到分类,比如新闻分类、病人分类等等。 本文介绍朴素贝叶斯分类器(Naive Bayes classifier),它是一种简单有效的常用分类算法。 一、病人分类的例子 让我从一个例子开始讲起,你会看到贝叶斯分类器很好懂,一点都不难。 某个医院早上收了六个门诊病人,如下表。 症状 职业 疾病 打喷嚏 护士 感冒 ...
朴素贝叶斯法(naive Bayes algorithm) 对于给定的训练数据集,朴素贝叶斯法首先基于iid假设学习输入/输出的联合分布;然后基于此模型,对给定的输入x,利用贝叶斯定理求出后验概率最大的输出y。 一、目标 设输入空间 是n维向量的集合,输出空间为类标记集合 = {c1, c2, ..., ck}。X是定义在 上的随机变量,Y是定义...

The Microsoft Naive Bayes algorithm can be used for association analysis, if the mining structure contains a nested table with the predictable attribute as the key. For example, you could build a Naive Bayes model by using the mining structure created in Lesson 3: Building a Market Basket ...
By using the Microsoft Naive Bayes algorithm, the marketing department can quickly predict an outcome for a particular customer profile, and can therefore determine which customers are most likely to respond to the fliers. By using the Microsoft Naive Bayes Viewer in SQL Server Data Tools, they ...
