Welcome to Weiyuan Chen’s Homepage!

My name is Weiyuan Chen. I’m a fourth-year student at Zhejiang University about to achieve a Bachelor's degree in Computer Science. Throughout my undergraduate study, I am very fortunate to have multiple research experiences as an intern in the field of Natural Language Processing supervised by Prof. Zhang Ningyu at Zhejiang University and ZJUKG Lab, Prof. Arman Cohan at Yale University and Allen Institute for AI, and Prof. Chen Zhao at NYU Shanghai and New York University.

Research Interests

My research interests lie in the intersection of machine learning (ML) and natural language processing (NLP). I have worked on projects about leveraging large language models (LLMs) to enhance scientific workflow, benchmarking LLMs on multi-displinary video QA tasks, using token-annotation and optimizing decoding strategies to enhance safety in LLM generations. These research experiences have equipped me with knowledge in machine learning and model training, ability to independently design research pipeline, conduct literature review and implement code and a passion for scientific research in natural language processing (NLP). My goal is to develop Trustworthy LLMs, Video-Language Models and explore LLM complex reasoning, especially:
(1) aligning LLMs with human values through preference fine tuning and improving model robustness
(2) investigating LLM complex reasoning, open-ended generation, question answering in specific tasks
(3) exploring the comprehension and generation capabilities of VLMs.
