Chanyoung Park, a member of POSTECH Data mining Lab (http://dm.postech.ac.kr), won the 10th place (top 1.1%) in the ACM RecSys Challenge 2015 (http://2015.recsyschallenge.com/) in which more than 850 teams from 49 countries have participated. The competition is the official challenge of the ACM RecSys conference, the premier international conference on recommender systems. The goal of this year's competition was to predict 1) whether the user will buy something or not, and if he/she is buying, 2) what items he/she will buy. The proposed model will be published and presented in the ACM RecSys conference 2015.
