Machine Learning is Fun! Part 2

Update: Machine Learning is Fun! Part 3, Part 4, Part 5 and Part 6 are now available! Also, don't forget to check out Part 1. In Part 1, we said that Machine Learning is using generic algorithms to tell you something interesting about your data without writing any code specific to the problem you are solving. This time, we are going to see one of these generic algorithms do something really cool -- create video game levels that look like they were made by humans.
