Naive Bayes is a classification technique based on Bayes’ Theorem with an assumption of independence among predictors. The Naive Bayes model is easy to build and particularly useful for very large data sets. When you have a large dataset think about Naive classification. Naive Bayes algorithm Proc...
In the Naive Bayes algorithm, we use Bayes' theorem to calculate the probability of a sample belonging to a particular class. We calculate the probability of each feature of the sample given the class and multiply them to get the likelihood of the sample belonging to the class. We then ...
Implementing the algorithm in R is a straightforward process. The following example demonstrates how train a Naive Bayes classifier and use it for prediction in a spam filtering problem.The following script is available in the bda/part3/naive_bayes/naive_bayes.R file....

In this tutorial we will discuss about Naive Bayes text classifier. Naive Bayes is one of the simplest classifiers that one can use because of the simple mathematics that are involved and due to the fact that it is easy to code with every standard programming language including PHP, C#, JAVA...

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 ...

If a pipeline does not adopt an algorithm of one of those types, say the i-th type, then ti will simply be the identity function. The theoretical goal in supervised machine learning is to find a pipeline that optimizes a prediction performance metric (error rate, log-loss, ..) averaged...
