Abstract: Venue recommendation systems aim to effectively rank a list of interesting venues users should visit based on their historical feedback (e.g. checkins). Such systems are increasingly deployed by Location-based Social Networks (LBSNs) such as Foursquare and Yelp to enhance their usefulness to users. In this talk, we show how recent adaptations of neural networks have allowed significant progress to be achieved in venue recommendation. In particular, we describe an adaptation of the Gated Recurrent Unit Architecture RNNs that allow to incorporate contextual information associated with the users' sequence of checkins (e.g. time of the day, location of venues) to effectively capture the users' contextual preferences. Further we investigate the risk & robustness of these approaches.
