Work Experience

Intern, NAVER, Seongnam, South Korea (Jan 2018 – Mar 2018)
NAVER is the most used search engine of South Korea. Developed and wrote a paper on a click model that predicts user click behavior, given a search query and the corresponding search engine results page.

Undergraduate Research Intern, Data Mining Lab, Seoul National University (Nov 2016 – Aug 2017)
Advisor: Professor U Kang
Researched on Deep Learning by writing a paper on applying neural network on coupled matrix factorization, and feature learning in signed directed networks. Participated in an industrial project, developing a time series data based stock price prediction project using deep learning.

Undergraduate Research Intern, Software Platform Lab, Seoul National University (Jul 2016 – Aug 2016)
Advisor: Professor Byung-Gon Chun
Developed a deep learning framework of Dolphin, a machine learning platform built on top of Apache REEF.
