About Me

Hi, I'm Chia-Hsuan Hsu (tongyu, @tongyu0924), an undergraduate student in Computer Science and Information Engineering at National Taiwan University of Science and Technology (NTUST). I am an undergraduate research student at HIS-LAB, advised by Prof. Yung-Yao Chen, with a research focus on camera-based visual localization systems.
I’m passionate about knowledge sharing and active in the developer community. I contribute to open-source projects in AI and machine learning (including microsoft/autogen, huggingface/diffusers, and scikit-learn), and served as a Core Team member at Google Developer Groups (GDG) On Campus NTUST in 2023.
