(HAIV)

2022.5) Congratulations! Our contributed talk proposal on face-embedded data visualization thumbnails of news articles is accepted by Computation+Journalism Conference (C+J). Joohee Kim (1st author, MS-Ph.D) will give a presentation at the conference.


2022.4) Congratulations! Hyunwook Lee (MS-Ph.D) and Joohee Kim (MS-Ph.D) have been awarded scholarship for research internship from Graduate School of AI, UNIST. They will do research internship in California, USA during 2022 Summer.


2022.3) Congratulations! Our paper on Modeling Video Browsing Behaviors and Video Exploration Interface Design is accepted for publication in CHI 22 Workshop--"Computational Approaches for Understanding, Generating, and Adapting User Interfaces" (First author: Joohee Kim, MS-Phd Student). She will present her work at CHI 22 (New Orleans, LA, USA).


2022.2) I serve on Program Committees of IEEE VIS 22 and VIS 22 Short.


2022.1) Congratulations! Our paper on Data-driven Storytelling with AI is accepted for publication in IEEE TVCG (top-tier, first author: Minjeong Shin, Visiting Scholar). She will present her work at VIS 22 (Oklahoma City, OK, USA).


2022.1) Congratulations! Our paper on neural memory networks for traffic forecasting is accepted for publication in ICLR 22 (top-tier, first author: Hyunwook Lee, MS-Phd student). He will present his work at the conference (virtual) in April.


2022.1) I am visiting UC Davis, CA, USA (2022/2~2023/2) for research collaboration with Dr. Kwan-Liu Ma (host).
