An overview of discrete diffusion models in natural language processing

Discrete Diffusion Models (DDMs) have recently emerged as a promising paradigm for text generation, providing an alternative to the dominant autoregressive (AR) approach. Unlike AR models that rely on sequential decoding and suffer from exposure bias, DDMs operate in discrete token space through iterative denoising, en...
