Good features are informative, independent, and simple. Learn about these concepts using a histogram to visualize a feature from a toy dataset in Python in this episode of Machine Learning Recipes. John Gordon shares best practices for what a good feature is and best practices to follow.

Check out the playlist to watch the next episode in the series as we reinforce concepts, introduce clearer syntax, spend more time on testing, and continue building intuition for supervised learning.
