Naive Bayes for Machine Learning

Last Updated on August 15, 2020

Naive Bayes is a simple but surprisingly powerful algorithm for predictive modeling.

In this post you will discover the Naive Bayes algorithm for classification. After reading this post, you will know:

  • The representation used by naive Bayes that is actually stored when a model is written to a file.
  • How a learned model can be used to make predictions.
  • How you can learn a naive Bayes model from training data.
  • How to best prepare your data for the naive Bayes algorithm.
  • Where to go for more information on naive Bayes.

This post is written for developers and does not assume any background in statistics or probability, although knowing a little probability wouldn’t hurt.

Kick-start your project with my new book Master Machine Learning Algorithms, including step-by-step tutorials and the Excel Spreadsheet files for all examples.

Let’s get started.
