The ROC curve is a great way to determine how well your classifier is doing but it can sometimes be tricky to actually generate the curve because of cryptic software instructions in languages such as R. In this tutorial we'll be using a few lines of python code to generate an interactive graph like the one shown above. To make this super simple we'll be using a python install that has all of the statistical, mathematical and graphical packages already included. This will go much more smoothly if you start off by uninstalling python from your system if you already have it installed. Once you've done that head on over to https://www.continuum.io/downloads and download the Anaconda python package which contains absolutely everything we need.
