Learned Relay Representations for Forward-Thinking Discrete Diffusion Models

arXiv:2605.22967v1 Announce Type: new Abstract: When Masked Diffusion Models (MDMs) generate sequences through iterative refinement, the rich internal computation over masked positions is discarded, forcing every subsequent refinement step to recompute the valuable internal information stored as model representations. To avoid a hard reset between denoising rounds, we propose Learned Relay Representations (Relay), a method that allows MDMs to be forward-thinking when denoising by explicitly learning how to propagate latent information for the benefit of future denoising steps.

Why this matters
Why now

This development emerges as the field of AI, particularly diffusion models, seeks greater efficiency and sophistication in generative processes, pushing beyond current computational limitations.

Why it’s important

Improved diffusion model efficiency enables more complex and higher-quality AI outputs, impacting a wide range of applications from media generation to scientific modeling by reducing computational overhead.

What changes

Diffusion models can now leverage learned relay representations to maintain internal information across denoising steps, moving away from iterative 'hard resets' and towards more 'forward-thinking' generation.
