How to Scale Machine Learning Data From Scratch With Python

Last Updated on December 11, 2019

Many machine learning algorithms expect data to be scaled consistently.

There are two popular methods that you should consider when scaling your data for machine learning.

In this tutorial, you will discover how you can rescale your data for machine learning. After reading this tutorial you will know:

• How to normalize your data from scratch.
• How to standardize your data from scratch.
• When to normalize as opposed to standardize data.

Kick-start your project with my new book Machine Learning Algorithms From Scratch, including step-by-step tutorials and the Python source code files for all examples.

Let’s get started.

• Update Feb/2018: Fixed minor typo in min/max code example.
• Update Mar/2018: Added alternate link to download the dataset as the original appears to have been taken down.
• Update Aug/2018: Tested and updated to work with Python 3.6.
