朴素贝叶斯分类算法(Naive Bayes Classification Algorithm)是一种基于贝叶斯定理和特征条件独立假设的分类方法。以下是对该算法的清晰介绍: 1. 基本概念 定义:朴素贝叶斯算法是应用最为广泛的分类算法之一,它假设给定目标值时属性之间相互条件独立。这个简化方式降低了贝叶斯分类算法的分类效果,但在实际应用中极大地简化了方...
前面几节介绍了一类分类算法——线性判别分析、二次判别分析,接下来介绍另一类分类算法——朴素贝叶斯分类算法1 (Naive Bayes Classifier Algorithm/NB)。朴素...

How the Algorithm Works The Microsoft Naive Bayes algorithm calculates the probability of every state of each input column, given each possible state of the predictable column. To understand how this works, use the Microsoft Naive Bayes Viewer in SQL Server Data Tools (as shown in the following...

Naive Bayes is a simple and easy to implement algorithm. Because of this, it might outperform more complex models when the amount of data is limited. Naive Bayes works well with numerical and categorical data. It can also be used to perform regression by using Gaussian Naive Bayes. ...
