About

I am a master's student at Computer Vision Lab (advisor: Prof. Bohyung Han), Seoul National University (SNU). Recently, I worked with as a research intern at Computer Vision Lab advised by Prof. Bohyung Han. Before joining Computer Vision Lab, I was a research intern at T-Brain and a visiting student at CLVR Lab at the University of Southern California advised by Prof. Joseph Lim. I also spent great time with Prof. Byoung-Tak Zhang at BioIntelligence Lab, SNU before enrollment.

My research interests come from a question, "How people can learn from small amounts of data or coarse data such as noisy or weak-labeled data and why machine cannot?" My goal is applying cognitive science to machine learning vice versa to dig into this question. Meanwhile, I am also interested in machine learning approaches to solve this question. Shortly, I am interested in three fields as follows:

  • Cognitive Science: Curiosity, Procedural Memory
  • Computer Vision: Action Recognition/Localization, Weakly-supervised Instance Segmentation
  • Reinforcement Learning: Exploration Strategies, Dynamics Randomization

Other Projects

Meta-Learned Suitability Assessor for Noisy Demonstration Sets

 Advisor : Joseph Lim
This project is for making a framework that selects suitable demonstration subsets in a noisy demonstraiton set including unsuitable demonstrations via meta learning. The model is able to automatically rank the suitability of given demonstrations so that it can learn from the most suitable subset. [paper], [project page]

Mar 2018 - Oct 2018

Multi Label Generative Adversarial Network

 Advisor : Byoung-Tak Zhang
This project was conducted in "Brain-Mind Behavior Individual Study(2071.416, prof. Sowon Hahn)" The model was combined Generative Adersarial Network part and traditional CNN Classifier. The data is made up of image, style labels, genre labels.

Sep 2017 - Dec 2017

Style Recognition of Artworks

This project is a final project of undergraduate course, "Computer Vision(M 1522.001000, prof. Gun Hee Kim)" from March to June. According to the project, Using SVM and PCA with featured layer of CNN is better than using Deep Neural Network only. Accuracy of style recognition is higher than human expert.
