CS Undergrad at UCAS | Exploring LLM Hallucinations & Memory

my_personal_photo.jpg

Hi! I am a third-year undergraduate majoring in Computer Science at UCAS, where I am fortunate to be advised by Prof. Fei Sun.

During my second year, I participated in the ysyx project to explore my interests in computer architecture. This experience helped me realize that this field was not the right fit for me. Currently, I am a research beginner in the NLP field, advised by Prof. Fei Sun, focusing on exploring hallucinations, memory, and knowledge mechanisms in LLMs. Looking ahead, I plan to further explore the MLSys and HPC domains before settling on a specific research area to specialize in.

Beyond academics, I am passionate about classical music, 3D modeling, and exploring new tools and applications on Linux/GitHub.
