MSRA Fellowship 2016:
(10/2016) Hyeonwoo was selected as one of the Microsoft Research Asia Fellows this year! The MSRA fellowship is a very competitive and prestigeous award, and Hyeonwoo is the second award winner in my lab, following Seunghoon in 2014.

Winning VOT 2016 Challenge:
(10/2016) We won the Visual Object Tracking (VOT) challenge with TCNN tracking algorithm this year! This is the back-to-back winning with MDNet in the last year challenge. Please refer to our arXiv paper our arXiv paper for the details. Congratulations, Hyeonseob and Mooyeol.

Sabbatical leave at Google
(08/2016) I am now with Google (LA) during my sabbatical leave for one year.

CVPR 2017:
(06/2016) I will be serving as an Area Chair for CVPR 2017.

Visual Question Answering and Visual Attention:
(06/2016) See our latest arXiv papers about visual question answering and visual attention.

CVPR 2016:
(03/2016) We have four papers accepted to CVPR 2016 (2 orals, 1 spotlight and 1 poster).

DPPnet for Image Question Answering:
(01/2016) The sourcecode of DPPnet paper is released in the project page.
(11/2015) We just released our arXiv paper about image question answering. This is a very unique and interesting approach based on dynamic parameter prediction for CNN. Check our paper.

Naver Faculty Award:
(01/2016) I received the Naver young faculty award.

MDNet for Visual Tracking:
(01/2016) The sourcecode of MDNet is released. Visit the project page.
(12/2015) I am very proud that MDNet won The Visual Object Tracking Challenge 2015 (VOT2015)! MDNet showed the best performance among 62 submitted or tested algorithms in the challenge. Read the result paper (Table 1 for summary) for the challenge details.
(10/2015) We obtained outstanding results of visual tracking using deep learning. Check our arXiv paper for details.

TransferNet: Transfer Learning for Semantic Segmentation:
(01/2016) The project page for TransferNet is open. Visit here.
(12/2015) Our paper about transfer learning for semantic segmentation is now available. Read our arXiv paper for details.
