I am Chu-Hsin Chen, a senior majoring in Computer Science and Information Engineering at National Taiwan University. With a strong foundation in Data Structures and Algorithms, I have also worked as a teaching assistant for a Machine Learning course, further strengthening my understanding of machine learning and its applications. My research experience includes working on large language models (LLMs) for English language learning and exploring multi-label classification in medical imaging using resampling methods and CNN-based transformers. Beyond machine learning, I am actively involved in the Web3 space. I participated in the Ethereum and Web3 security bootcamp organized by DeFiHackLab and now compete in audit competitions.
