Research Abstract

In this project, we planed to address a start-up problem, which means the poor prediction accuracy of recommendation systems for new users or new items. For this purpose, we developed a TrBagg algorithm, which utilizes information of other users' data. We tested this algorithm on a tag recommendation task and succeeded to improve the prediction accuracy. We also tried to settle other problems related to recommender systems.
