About me

I'm a third year undergraduate student (2022.9 - Present) in Turing Class, Chu Kochen Honors College, Zhejiang University.

My research interests now focus on two directions in deep learning:

• Investigating the mathematical principles behind deep learning models to explain its empirical successes and failure modes.
• Designing efficient algorithms to accelerate inference/training and reduce memory overhead.

I have studied post-training quantization on video generation models (DVD-Quant). I'm also exploring RL for LLM reasoning recently.
