DTCA Framework for Token Credit Assignment in Diffusion Language Models
October 25, 2026
DTCA enables reinforcement learning for diffusion language models by estimating token-level contributions through improvements in prediction confidence during the denoising process. This method addresses the difficulty of assigning rewards to specific tokens in iterative, bidirectional text generation.
