Diffusion Forcing: Next-token Prediction Meets Full-Sequence Diffusion
Paper • 2407.01392 • Published • 39Note [2R] This paper presents Diffusion Forcing, a new training paradigm where a diffusion model is trained to denoise a set of tokens with independent per-token noise levels.
No Training, No Problem: Rethinking Classifier-Free Guidance for Diffusion Models
Paper • 2407.02687 • Published • 21Note 【2R】 Classifier-free guidance (CFG) has become the standard method for enhancing the quality of conditional diffusion models. However, employing CFG requires either training an unconditional model alongside the main diffusion model or modifying the training procedure by periodically inserting a null condition. A new method, independent condition guidance (ICG), which provides the benefits of CFG without the need for any special training procedures.
