Adaptive Refinement Control
PRR introduces a lightweight, token-wise controller that dynamically regulates the refinement strength for each token during the diffusion decoding process. Unlike uniform refinement rules, PRR identifies when tokens have converged, reducing redundant computation and enabling earlier unmasking.
Trajectory-Grounded Supervision
The framework derives a novel token-level notion of empirical convergence progress from full decoding rollouts. This provides a continuous, trajectory-based signal for refinement necessity, moving beyond instantaneous uncertainty measures to account for how a token's prediction changes over its future refinement trajectory.
Dynamic Self-Evolving Training
A core challenge in refinement control is the supervision shift, where changes to the refinement rule reshape future refinement trajectories. PRR addresses this with a progressive self-evolving training scheme, using rollouts from the current controller to construct supervision for the next, ensuring adaptability and stability.
Temperature-Based Distribution Shaping
PRR regulates refinement by modulating the sharpness of predictive distributions through temperature-based shaping. Converged tokens can be unmasked earlier by sharpening their distributions (lower temperature), while unconverged tokens maintain exploration (higher temperature).

Case Study: PRR in Action - Mathematical Reasoning
PRR demonstrates superior performance in mathematical reasoning tasks, optimizing inference steps while maintaining accuracy. For example, in Question 2, PRR achieved a 4.83x speedup (Latency and NFE) compared to baseline, reducing NFE from 256 to 53 while successfully solving the problem. This showcases PRR's ability to efficiently handle complex reasoning without sacrificing correctness.
Key Takeaways:
- Adaptive Decoding: PRR intelligently identifies and reduces redundant refinement steps.
- Significant Speedup: Demonstrates up to 4.83x faster inference on challenging tasks.
- Preserved Accuracy: Solves complex problems correctly with significantly fewer computations.
