Forward-Learned Discrete Diffusion: Learning how to noise to denoise faster
Researchers propose Forward-Learned Discrete Diffusion, a technique that replaces fixed noise schedules in discrete diffusion models with learnable forward processes. By parameterizing both marginal and posterior distributions rather than enforcing Markovian constraints, FLDD reduces the gap between target and model distributions, enabling faster few-step generation. This addresses a core efficiency bottleneck in discrete diffusion across domains like text and categorical data, potentially accelerating inference for a class of generative models that has gained traction as an alternative to continuous diffusion.62
