how the naive Bayes classifiers work, why it makes sense to define them the way they are and how to implement them in Python using NumPy. You can find the code onmy Github. It might help a bit to check out my primer on Bayesian statisticsA gentle Introduction to Bayesian Inferenceto get...

Conditional probabilities are fundamental to the working of the Naive Bayes formula. Tables of conditional probabilities must be created in order to obtain values to use in the Naive Bayes algorithm. The R package e1071 contains a very nice function for creating a Naive Bayes model: library(e107...
In this article I show how to implement a simplified naive Bayes classification algorithm using the C# language. The best way to understand where this article is headed is to take a look at the demo run in Figure 1. The demo program sets up 40 dummy data items. Each item has three ...
The key to understanding the INBIAC algorithm so that you’ll be able to modify the demo code to meet your own needs is understanding Naive Bayes inference. Naive Bayes is best explained by example. Suppose you have the eight tuples shown in Figure 1 and you want to p...
The naive Bayes classifier (NB) was first proposed by Duda and Hart in 1973. Its core idea is to calculate the probability that the sample belongs to each category given the characteristic value of the sample and assign it to the category with the highest probability. This algorithm does not...
Variable selection methods play an important role in the field of attribute mining. The Naive Bayes (NB) classifier is a very simple and popular classification method that yields good results in a short processing time. Hence, it is a very appropriate cl

The goal of a naive Bayes classification problem is to predict a discrete value called the class label. The idea is best explained by a concrete example. Suppose you have a set of 40 data items where each item consists of a person's occupation (actor, baker, clerk or diver), eye color...
