Hello! My name is Jeongin Kim, and I am a third-year student in the integrated MS–PhD program at Ewha Womans University, advised by Professor
Junhyug Noh. As a member of the
Practical AI Lab (PAI Lab), my research focuses on developing reliable and annotation-efficient learning methods for semantic segmentation, with a particular emphasis on active learning and weakly-/semi-supervised learning.
Reducing reliance on costly human annotation is key to scaling visual learning to real-world applications. Currently, I investigate how foundation models such as SAM can provide reliable supervision for semantic segmentation under limited annotation budgets.

ASH-MIL is a weakly-supervised framework for thoracic disease detection in chest X-rays that combines parallel anatomy-structured branches with hierarchical MIL, injecting anatomical priors into decoder cross-attention to enable anatomically grounded localization without bounding box supervision.

We propose a two-stage active learning pipeline for semantic segmentation under extremely low labeling budgets, which leverages a pre-trained diffusion model for diverse feature extraction and introduces an uncertainty score to select the most informative pixels for annotation.
