Hello, I'm Jiwon Kang

I am an Integrated M.S./Ph.D. student at KAIST AI (Kim Jaechul Graduate School of AI), advised by Seungryong Kim (CVLAB). Starting my research career in 3D vision, I expanded my focus during my Master's to Generative AI, practical applications, and Unified Multimodal Models (UMMs). Recently, I am interested in the challenge of world modeling by combining 3D vision capabilities with generative knowledge.

Transferability Between Understanding and Generation in Unified Multimodal Models

Transferability Between Understanding and Generation in Unified Multimodal Models

Jiwon Kang*, Heeji Yoon*, Jaewoo Jung, Jaewon Min, Minkyeong Jeon, Biyeon Hwang, Sangwon Jung, Seungryong Kim†
ECCV
  • Investigated how understanding and generation capabilities (e.g., counting) transfer to one another within unified multimodal models.
  • Showed that transferability depends on the model architecture, and proposed a practical post-training strategy for unified multimodal models that leverages transferability.

APPLE: Attribute-Preserving Pseudo-Labeling for Diffusion-Based Face Swapping

Jiwon Kang*, Yeji Choi*, JoungBin Lee, Wooseok Jang, Jinhyeok Choi, Taekeun Kang, Yongjae Park, Myungin Kim, Seungryong Kim†
CVPR
  • Prior diffusion-based face swapping methods focused on changing facial identity, failing to preserve facial attributes.
  • Proposed a novel pseudo-labeling framework that preserves facial attributes while swapping identities, achieving Pareto-optimal results.

A Noise is Worth Diffusion Guidance

Donghoon Ahn*, Jiwon Kang*, Sanghyun Lee, Jaewon Min, Wooseok Jang, Minjae Kim, Hyungwon Cho, Sayak Paul, SeonHwa Kim, Eunju Cha†, Kyong Hwan Jin†, Seungryong Kim†
ICLR
  • Showed that classifier-free guidance can be replaced by refining the initial noise.
  • Enabled high-quality generation without a guidance pass, highlighting the importance of the initial noise in diffusion models.

Where and How to Perturb: On the Design of Perturbation Guidance in Diffusion and Flow Models

Where and How to Perturb: On the Design of Perturbation Guidance in Diffusion and Flow Models

Donghoon Ahn*, Jiwon Kang*, Sanghyun Lee, Minjae Kim, Wooseok Jang, Jaewon Min, Sangwu Lee, Sayak Paul, Seungryong Kim†
NeurIPS
  • Systematically studied perturbation guidance in diffusion and flow models.
  • Showed that perturbing different layers/heads in a diffusion model exhibits different effects on the generated samples, which can be systematically combined to improve user-specified attributes via the proposed framework.
