Abstract
A method for accelerating score-based generative models (SGM) is provided, including setting a frequency mask (R) and a space mask (A) and a target sampling iteration number (T); sampling an initial sample (x); conducting iteration comprising steps as follows: sampling a noise term; applying a preconditioned diffusion sampling (PDS) operator (M) to the noise term and thus generate a preconditioned noise term; calculating a drift term; applying the transpose of the PDS operator (M) and then applying the PDS operator (M) to the drift term, and thus generate a preconditioned drift term; diffusing the sample of each iteration (x); and outputting the result.
