Poor Man's Topological Data Analysis
Posted: Sun Nov 10, 2013 1:32 am
At the 2012 Sports Analytics Conference, Muthu Alagappan gave a presentation that redefined the positions on the court. The presentation can be found here:

At that conference, Muthu’s new list had 13 positions. He reduced that number to 10 for a TedX talk:

Alagappan uses topological data analysis (TDA) to redefine the positions and create some really cool images. TDA is complicated, still developing, and fascinating field that studies the shape of a set of data. If you don’t want to or don’t have the time to learn TDA, you can still create 2D visualizations of higher dimensional data.
See our most recent post for a couple examples:

We started simple with this post. Our plan is to post progressively more complicated and more interesting images. We will do this by including more advanced stats on the players and by using more involved visualization techniques.
