VLA-Rolling: Fewer Denoising Steps, Better Control via Adaptive Action Reuse
VLA-Rolling is introduced, a lightweight inference framework that reuses action tails through three stages: action-tail inheritance, per-action confidence estimation, and confidence-guided refinement through renoising and denoising budget allocation, while the underlying VLA remains frozen.
