Workshop on the RecSys Challenge 2015

YOOCHOOSEIn this year’s edition of the RecSys Challenge, YOOCHOOSE provided a collection of sequences of click events; click sessions. The goal of the challenge was to predict whether a user is going to buy something or not, and if he is buying, what would be the items he is going to buy.
During this workshop, accepted contributions are presented.
