I am a first-year Ph.D. student at Gaoling School of Artificial Intelligence, Renmin University of China, advised by Prof. Chongxuan Li.

My research interests lie in deep generative models and reinforcement learning. Recently, I have been focusing on diffusion language models.

    Proves that masked diffusion models admit a simplified training objective and a time-independent network parameterization,
    both of which have since become standard.
