arXiv:2605.25638v1 Announce Type: new Abstract: Policy loss estimation remains a fundamental and long-standing challenge in reinforcement learning (RL) for diffusion language models (dLLMs). We introduce Reinforcement Learning from Denoising Feedback (RLDF), a novel training paradigm that leverages feedback obtained from rollout and training processes to facilitate accurate and efficient policy loss estimation. To balance the trade-off between computational efficiency and estimation effectiveness, RLDF optimizes the model toward the clipped clean state $\hat{x}_0$ from intermediate noisy state
The continuous evolution of diffusion models and the persistent challenges in effectively applying reinforcement learning to them necessitate novel approaches like RLDF.
Improving policy loss estimation in dLLMs directly impacts the efficiency and performance of advanced AI systems, accelerating their deployment and capabilities.
The introduction of RLDF provides a more accurate and computationally efficient method for training diffusion language models, potentially leading to faster development cycles and more sophisticated AI outputs.
