Rethinking Soft Tokens for Parallel Decoding in Diffusion Language Models

Diffusion language models (DLMs) enable parallel generation by predicting and committing multiple tokens at each denoising step, yet they can generate individually plausible but mutually inconsistent tokens. Recent work shows that \emph{soft tokens} can mitigate this issue by representing uncertain positions with conti...

Speculative Correction: Draft-then-Refine Decoding for Diffusion Language Models

Overall, same-model draft-and-refine provides evidence that bidirectional refinement is a useful decoding primitive for DLMs, while speculative correction demonstrates a training-free route to fast DLM generation.

Unlocking More Granular Control of Memory-Efficient LLM Finetuning

This work systematically investigates the impact of the projection unit on LoRP methods, and extends existing LoRP approaches by introducing an additional degree of freedom, projection granularity, beyond the traditional rank hyperparameter, which enables a framework capable of performing fine-grained projections, whic...
