How to Make a Learning Algorithm Work for You

It took 20 years to go from the concept of a learning algorithm to something that can solve a really important practical problem. That's because you needed a lot more computing, a lot more data and a lot better algorithms. Learning is a universal method and it trades off computing for labor. And there's still, by the way, I mean, model based solutions are still useful for small problems, but they don't scale very well.
