I am a Ph.D student of Data Mining Lab at Seoul National University, where I am fortunate to be advised by Prof. U Kang. I received my B.S. in Computer Science and Engineering at Hanyang University. My research interests include recommender systems for various practical scenarios, such as sequential recommendation, news recommendation, IoT recommendation, and bundle recommendation.

I am highly interested in recommender systems for valuable services. I have studied sequential recommendation, news recommendation, IoT recommendation, and bundle recommendation. In addition, I am fascinated by researching recommender systems that model user behaviors in real-world services and improve user experiences. |

Hyunsik Jeon, Bonhun Koo, and U Kang BigData 2019, Los Angeles, USA Samsung HumanTech Paper Award, BigData Student Travel Grant [paper / slides / homepage / bib] Given a sparse rating matrix and an auxiliary matrix of users or items, how can we accurately predict missing ratings considering different data contexts of entities? We propose DaConA which accurately predicts ratings utilizing auxiliary matrix, based on neural networks. |

Haekyu Park, Hyunsik Jeon, Junghwan Kim, Beunguk Ahn, and U Kang arXiv (2017) [arxiv / homepage / bib ] Given a social network and ratings, how can we correctly recommend proper items and provide a persuasive explanation for the recommendation? We propose UniWalk which accurately recommends items and explains the reasons while exploiting both social network and rating data. |
