Accelerating Diffusion Model Sampling with OLSS: A Linear Subspace Approach

This article presents the OLSS (Optimal Linear Subspace Search) algorithm, a novel diffusion‑model sampling accelerator that models acceleration as a linear subspace expansion, unifies existing methods, introduces trainable scheduler coefficients solved via least‑squares, and demonstrates significant speed and quality gains on Stable Diffusion benchmarks.
