LLaDA-Rec: Discrete Diffusion for Parallel Semantic ID Generation in Generative Recommendation

Teng Shi, Chenglei Shen, Weijie Yu +6

Generative recommendation represents each item as a semantic ID, i.e., a sequence of discrete tokens, and generates the next item through autoregressive decoding. While effective,…
