StrideDiffusion: Accelerating Diffusion Models for Time-series Generation

Results show that spectral evolution provides a practical and principled signal for fast time-series diffusion sampling, and a training-free spectral-aware sampler that adaptively selects the denoising stride from band-level activity.
