[Multinomial Naive Bayes][MLE极大似然估计][二分类] 这里直接是一个二分类,比较简单 本质上就是把各个事件看成独立的,概率分别计算,概率相乘求出条件概率(后验概率) 然后为了防止概率过小,取log,连乘变为连加,即求和 网页上相关的资料很多,这里就不再赘述了,直接上代码: 推荐视频: https://www.bilibili.com...

Python Multinomial Naive Bayes 之前在一次跟“某Fish”客户进行交谈时,我在的需求下学习了多项贝叶斯(Multinomial Naive Bayes)这个模型。 在了解多项贝叶斯模型之前,我们首先来了解一下朴素贝叶斯(Naive Bayes)模型。 贝叶斯定理所描述的,即为一个抽象事件A在抽象事件B发生的前提下,有多大概率会发生抽象事件A,其...
Leveraging natural language processing concepts, this research explores the application of the Multinomial Naive Bayes (MNB) algorithm to identify and classify programming languages used in source code files. MNB is a relatively simple and fast algorithm for text classification. The study utilizes a ...
