B.E. in Computer Science & Technology, Beihang University
Junior & Senior High School Education, High School Affiliated to Southwest UniversityI am currently pursuing a Bachelor's degree in Computer Science and Technology at Beihang University, studying at the Top-Notch Computer Talent Program, School of Advanced Technology and Engineering.
My research direction is at the intersection of Artificial Intelligence (AI) and Software Engineering (SE), including:
- AI for Code Generation, enhancing code generation using large language models (LLMs), including function-level code generation and project-level code generation.
- LLM Acceleration, improving LLM inference speed by using methods such as speculative decoding, retrieval and copy.
