This article gives a mathematically rigorous yet easily accessible introduction to Bayes’ theorem and the foundations of naive Bayes learning. Starting from the fundamental elements of probability theory, this article outlines all steps leading to one of the oldest workhorses of machine learning: the...
朴素贝叶斯分类(Naive Bayes classifier) 根据贝叶斯定理有: p(C_k | \mathbf{x} )=\frac{p(C_k)p(\mathbf{x}|C_k ) } { p(\mathbf{x} )}= \frac{p(C_k \cap \mathbf{x} )} {p(\mathbf{x})}= \frac{p(C_k , \mathbf{x} )} {p(\mathbf{x})}= \frac{p(C_k , x_{1}...
朴素贝叶斯分类器(Naive Bayes Classifier),包括其概念、应用、原理、示例及总结等内容: 1 概念 它是一种监督学习技术,通过贝叶斯定理计算新数据属于不同类别的概率。 2 应用 常用于数据分类(尤其是文本分类)和情感分析,如自然语言处理中判断新闻好坏、分析推特对选举或公投的影响、识别推文是否来自俄罗斯机器人等。

The Na?ve Bayes Classifier algorithm is designed for efficient identification of classes to measure the relationship between disease features and improving disease prediction rate. Experimental analysis shows that RS-RMC is used to reduce the execution time for extracting the disease feature with minimum...
