DACA-GRPO: Denoising-Aware Credit Assignment for Reinforcement Learning

Denoising-Aware Credit Assignment: what actually changed

Apple Machine Learning Research reports: DACA-GRPO: Denoising-Aware Credit Assignment for Reinforcement Learning in Diffusion Language Models. Diffusion large language models are a compelling alternative to autoregressive models, yet existing RL methods for diffusion treat all denoising steps as equally important and rely on biased, high-variance likelihood estimates. We identify two fundamental weaknesses: the absence of temporal credit assignment across…
