In the forward process, uniform diffusion jumps a token to any other category in the vocabulary at a uniform rate, ultimately tending toward a uniform distribution, and its reverse denoising is more difficult.

UnverifiedDiffusion language models often require dozens or even hundreds of denoising iterations to ensure generation quality, with each step requiring one complete forward pass, so the actual speed advantage is not always apparent.75% similarUnverifiedThe reverse process of a diffusion model can only be approximated as a Markov chain when the number of noise-adding steps is sufficiently large and the noise at each step is sufficiently small.73% similarUnverifiedThe number of iterative denoising steps is a tunable hyperparameter; more steps generally yield higher generation quality but take longer, while fewer steps are faster, providing a quality-efficiency trade-off.72% similarVerifiedStochastic gradient descent (SGD) uses only one sample at a time, which is fast but produces noisy update directions.72% similarUnverifiedThe state shift caused by the number change is very small, and random noise can also fall in equally "busy" directions; the state change is much larger and easier to read out when replaced with random words, thus rejecting the "crowding hypothesis."70% similar
