Here is Guoxin Chen (陈国鑫).
I am now a second-year master student at Institute of Computing Technology, Chinese Academy of Sciences. My research focuses primarily on Natural Language Processing and Graph Mining.
Currently, I have a strong research interest focusing on Natural Language Reasoning (particularly mathematical reasoning), Tool Learning, and Retrieval Augmented Generation. I am committed to enabling LLMs to possess human-like reasoning and tool-using capabilities.
You can find my CV here: Guoxin Chen’s Curriculum Vitae.
