JinYeong Bak

Research Statement

My research interests are in machine learning and data mining. In particular, I study probabilistic Bayesian topic models which aims to discover latent patterns such as topics in unannotated data, and efficient inference methods of it for handling large corpus.

EXPERIENCES

• Research Intern, Microsoft Research Asia, Beijing, China, Sep 2013 - Feb 2014
  :I interned with Chin-Yew Lin in the Knowledge Mining group at Microsoft Research Asia. I developed a topic model to identify self-disclosure in Twitter conversations. This work is published at EMNLP 2014 as full paper.
• Junior Data Scientist, United Nations Global Pulse Lab Jakarta, Jakarta, Indonesia, June 2016 - Aug 2016
  : I interned with Jonggun Lee in the United Nations Global Pulse Lab Jakarta. I developed a topic model based methodology for expanding relevant keywords for specific subjects to identify related tweets in Twitter. This work is not published yet.
