Classification algorithms learn how to assign class labels to examples (observations or data points), although their decisions can appear opaque.

A popular diagnostic for understanding the decisions made by a classification algorithm is the decision surface. This is a plot that shows how a trained machine learning algorithm predicts a coarse grid across the input feature space.
A decision surface plot is a powerful tool for understanding how a given model “sees” the prediction task and how it has decided to divide the input feature space by class label.
In this tutorial, you will discover how to plot a decision surface for a classification machine learning algorithm.
