DESCRIPTION

At foursquare, we believe there is a huge opportunity to apply machine learning algorithms to the collective movement patterns of millions of people and build new services which help people better understand and connect with places.Foursquare is now aware of 25 million places worldwide, each of which can be described by unique signals about who is coming to these places, when, and for how long. We employ a variety of machine learning algorithms at foursquare to distill these signals into useful data for our app and our platform.In the slides below, we talk briefly about the data at foursquare and some interesting applications of machine learning. Enjoy!

Learning with location data

• Check-ins are a rich source of data that describe human behavior

• We apply machine learning algorithms to the collective movement patterns of millions of people to build exciting new services

Recommendation engine

•foursquare explore provides realtime recommendations using:• location• time of day• check-in history• friends preferences• venue similarities

Open questions

• How to measure similarity between people and places?• How to determine influence in large

networks of people and places?• What statistics can we use to describe

people’s behavior in the real-world?• How do we predict what information will be

timely and relevant to a user?
