D5P4: Partition Determinantal Point Process for Diversity in Parallel Discrete Diffusion Decoding
arXiv:2603.19146v2 Announce Type: replace-cross Abstract: Discrete diffusion models are promising alternatives to autoregressive approaches for text generation, yet their decoding methods remain under-studied. Standard autoregressive search procedures, such as beam search, do not directly apply to iterative denoising, where hypotheses are complete intermediate sequences rather than left-to-right prefixes. Furthermore, existing diffusion decoding procedures only provide limited control over the diversity and coverage of retained hypotheses. In this work, we introduce D5P4, a beam-style decoding
The continuous improvement of discrete diffusion models for text generation necessitates more sophisticated and controlled decoding methods that existing approaches do not fully address.
Improved decoding for discrete diffusion models will enhance the quality and diversity of AI-generated text, leading to more robust and versatile AI applications across various industries.
The introduction of D5P4 offers a new beam-style decoding mechanism for discrete diffusion models, promising better control over diversity and coverage compared to prior methods.
