From NLP to robotics and music information retrieval, each of us have diverse research interests. This is the being we want to create; a companion to whom you can chat about your daily life and emotions; an assistant who can report up-to- date information to you, and to whom you can discuss your own ideas. A vital and friendly being to the modern society, which soothes the loneliness of people and relieves the information asymmetry among people.

Jaemin C. - Team leader

I am pursing a Bachelor's degree in Industrial Engineering. I have been interested in Operations Research and Machine Learning since 2015, and have participated in the following group research projects: "Analysis and optimization of nursing assignment for homecare service delivery at Polytechnique Montreal", "DeepCoding: Pseudocode-Python code translation at HKUST". Since August 2016, I have been working as a NLP researcher at DataNada, a Korean AI startup, with brilliant Kagglers. Here I am taking a leading role in developing a Korean POS-tagger, a Parser and a generative chatbot based on deep learning.

Sanghyun Y.

I have a dream that one day machines can understand the human mind and be much more useful tools to work with. Now, as an undergraduate student, I’m pursuing the future as a researcher in the field of NLP. Especially, applications of deep learning methods to NLP attract my attention. Accordingly, I have been involved in a machine translation project at Kyomin Jung's MILAB in SNU since January 2016 as a research intern. The Alexa Prize will be the great opportunity to deepen my understanding of NLP and deep learning.

Kyomin Jung - Faculty advisor

I am an Associate Professor in the Electrical and Computer Engineering department. I received my Ph.D. at MIT in 2009 and my B.Sc. at SNU Mathematics Dept. in 2003. I was a recipient of the excellent new faculty funding from NRF Korea in 2012, and I was a gold medalist at IMO (International Mathematical Olympiad) in 1995. My research area includes Machine Learning algorithms, Recommendation systems, and Natural Language Processing.
