Subject: Machine Learning and Mechanical Investing
There's quite a bit of interest in Machine Learning over at Portfolio 123. This book sounds interesting:

Introduction to Statistical Learning
"I recently came across this book by Stanford University and it may be the best one I have seen yet on the topic."

The book is available for free at https://www.statlearning.com/
A free online companion course is available through edX.

"we're trying to launch our AI/ML factors this month in beta. It's a huge deal for us and very big, costly project."

I think Machine Learning will soon be applied successfully to stock pricing. I doubt I will be the one who programs this, but am interested in the topic. What effect will Machine Learning have on Mechanical Investing in the next 5 years? It could be an opportunity as people invest in dubious ML ideas. Or the market could become more efficient.
