Moneyball – Feature Engineering

I first read this book in college because our catcher recommended it to me. It was the first Michel Lewis book I ever read and I happened to be in my first year of studying economics so it set off all sorts of mental connections.

I was thinking about Slugging Percentage, which I first heard of through Moneyball, recently in relation to Feature Engineering and the amazing things that you can learn when you combine domain knowledge (baseball) with statistics.

The novelty of how Paul Depodesta was looking at the data, structured collection of player statistics enabled the Oakland A’s to find undervalued talent and evaluate each player’s contribution to the team’s wins.

What I find so cool about rereading this book, is now I actually know enough math to replicate the analytical approach and apply the same methods to other business problems – just took me about 20 years to get there.
