The Data Science Lab Data Prep for Machine Learning: Splitting Dr. James McCaffrey of Microsoft Research explains how to programmatically split a file of data into a training file and a test file, for ...

Before data scientists can run machine learning models to tease out insights, they’re first going to need to transform the data—reformatting it or perhaps correcting it—so it’s in a ...

Machine-learning algorithms use statistics to find patterns in massive* amounts of data. And data, here, encompasses a lot of things—numbers, words, images, clicks, what have you.

A good way to understand data file splitting and see where this article is headed is to take a look at the screenshot of a demo program in Figure 1. The demo uses a small 12-line text file named ...
