I am currently a master student in the Computer Vision Lab at the POSTECH, advised by Prof. Suha Kwak.

My research broadly focuses on the computational challenges at the intersection of machine learning and physical world understanding. Ultimately, I aim to build intelligent systems that can perceive and interact with complex environments much like humans do. Specifically, my current interests include:

Vision-Language-Action Model (VLA)
World Action Model (WAM)
Multimodal Learning
3D Vision

I am always eager to exchange ideas and explore potential research collaborations. If my work aligns with your interests, please feel free to reach out to me!

Community detection (CD) on signed networks is crucial for understanding how positive and negative relations jointly shape network structure. However, existing CD methods often yield inconsistent communities due to noisy or conflicting edge signs. In this paper, we propose ReCon, a model-agnostic post-processing framework that progressively refines community structures through four iterative steps: (1) structural refinement, (2) boundary refinement, (3) contrastive learning, and (4) clustering. Extensive experiments on eighteen synthetic and four real-world networks using four CD methods demonstrate that ReCon consistently enhances community detection accuracy, serving as an effective and easily integrable solution for reliable CD across diverse network properties.
