 # Notation and Terminology
 
-In Section \ref{@mnist} we introduced the MNIST handwritten digits dataset. Here we describe how the task of automatically reading these digits can be framed as a machine learning challenge and in doing so we introduce machine learning mathematical notation and terminology used throughout this part of the book.

 Originally, sorting mail received in the post office involved humans reading zip codes, written on the envelops. Today, thanks to machine learning algorithms, a computer can read zip codes and then a robot sorts the letters. We will learn how to build algorithms that can read a digitized handwritten digit.
