How does Foursquare’s presence system work?

“This is just a projection into a flat image of a model with hundreds of dimensions, but it gives an idea of what the world actually looks like to our phones. We use this and many other signals, (like nearby wifi, personalization, social factors, and real-time check-ins) to help power the push notifications you see when you’re exploring the city.”
