Liu Yifeng

NLP & AI4Science Researcher

I am a student researching on the field of NLP and AI4Science. Python, C++ and LaTeX are my main program and text-generation languages. I have participated in many projects of AI. And I am out-going. See my Blog or Github.

Let's Begin

My Work

CodeGeeX: A Code Generative Model for Multilingual Program Synthesis

Provider the idea of soft-score hierarchy for training;

KDD '23 paper: CodeGeeX: A Pre-Trained Model for Code Generation with Multilingual Benchmarking on HumanEval-X.

See CodeGeex Blog for more details.

This is me

NLP & AI4Science Researcher

I am currently a Ph.D. student at UCLA, researching on optimization and architectures of LLMs. I was previously a Yao Class Student from Tsinghua University researching on the fields of NLP following Zhilin Yang (Now CEO of Moonshot Inc.) and AI4Science following Sheng Wang as a visiting student in the University of Washington.


I can program well with C++, Python, MatLab, HTML5 as well as LaTeX. And I have participated in lots of projects of AI, especially in the field of NLP.


I has won the gold medal in the 36th CPhO and obtained the Outstanding Award of Interdisciplinary Contest In Modeling(ICM). Also, I has got the comprehensive award of Tsinghua University twice.


I am responsible, for which I was once elected as the monitor of Yao Class. And I am also sunny, optimistic as well as approachable.
