Building upon our previous work, Immiscible Diffusion (NeurIPS 2024), we present an improved version with deeper theoretical analysis and a significantly more efficient and effective implementation. This improved approach accelerates diffusion training across a wide range of

SVD is playing an increasingly important role in LLM. It has been widely used for model compression (e.g., our previous Dobi-SVD) and memory-efficient training (e.g., GaLore). Samir, Xiuyu, and Junxian take a creative step further by leveraging SVD to dynamically select a sparse

Becoming an RL diehard in the past year and thinking about RL for most of my waking hours inadvertently taught me an important lesson about how to live my own life. One of the big concepts in RL is that you always want to be “on-policy”: instead of mimicking other people’s
