PART 1
Getting Started
Downloading the Datasets
and Example Code
This book is about using Python to perform machine learning tasks. Of course, you
can spend all your time creating the example code from scratch, debugging it, and
only then discovering how it relates to machine learning, or you can take the easy
way and download the prewritten code from the Dummies site (see the Introduc-
tion of this book for details) so that you can get right to work. Likewise, creating
datasets large enough for algorithm learning purposes would take quite a while.
Fortunately, you can access standardized, precreated data sets quite easily by
using features provided in some of the data science packages (which also work
just fine for all sorts of purposes, including learning to work with algorithms).
The following sections help you download and use the example code and datasets
so that you can save time and get right to work with algorithm-specific tasks.
