Diffusion language models enhanced with new interpolation and refinement techniques · 2 sources tracked

By PulseAugur Editorial · [2 sources] ·

Two research papers explore advancements in diffusion language models, focusing on improving their efficiency and performance. The first paper, "Lost in Interpolation," introduces Spherical Soft-Masking (S-SM) to address the geometric properties of embedding spaces, leading to significant MAUVE gains and lower perplexity. The second paper, "Inference-Time Scaling of Diffusion Language Models via Trajectory Refinement," presents particle Gibbs sampling (PG-DLM) for trajectory-level refinement, enabling better reward-guided generation and improved accuracy on benchmarks like GSM8K. AI

IMPACT These advancements offer improved efficiency and performance for diffusion language models, potentially leading to better generative capabilities and more accurate task completion.

    Lost in Interpolation: Why Predictive Feedback Fails in Diffusion Language Models

    arXiv:2608.06529v1 Announce Type: new Abstract: Soft-masking accelerates the convergence of Masked Diffusion Language Models (MDLMs). Existing formulations build this blend with linear interpolation (LERP) in the raw embedding space, which implicitly treats that space as Euclidea…

    Inference-Time Scaling of Diffusion Language Models via Trajectory Refinement

    arXiv:2507.08390v5 Announce Type: replace Abstract: Discrete diffusion models have recently emerged as strong alternatives to autoregressive language models, matching their performance through large-scale training. However, inference-time control remains relatively underexplored.…
