Imagine the scene: a field of ants. When we look at it, we see three distinct groups. It 'just seems obvious' that there are three. But in fact that 'just seems obvious' feeling is what your brain tells you when it's just done a terrifyingly complicated calculation and doesn't feel the need to explain the details.
But how would we go about getting a computer to work out how many different anthills there are in such a picture, and where they're likely to be? It turns out that all you need to do is take averages.
We'll tackle this problem in our next hands-on coding session, which will be accessible to all, from beginner to expert. Come along with a laptop to join in the coding, or just to chat and enjoy a beer with other Clojurians.
