One Versus One vs. One Versus All in Minutes

In this quick machine learning tutorial, we introduce you to the concepts of one-versus-one and one-versus-all in classification. In classification models, you will often want to predict one class from another. This is called binary classification, or one-versus-one. But what if you have more than two classes to predict? This is where one-versus-all is introduced. We will explain the difference between these two classification techniques, and describe scenarios where you may want to use one over the other.
