Gotta Go Fast When Generating Data with Score-Based Models

This repo contains the official implementation for the paper Gotta Go Fast When Generating Data with Score-Based Models, which shows how to generate data as fast as possible with score-based models using a well-designed SDE solver. See the blog post for more details.

This code is a heavy modification of the Generative Modeling through Stochastic Differential Equations repository.

To run the experiments in the paper

See the requirements. Change the settings and folders in https://github.com/AlexiaJM/score_sde_fast_sampling/blob/main/experiments.sh and run parts of the script to run the CIFAR-10, LSUN-Church, and FFHQ experiments.

The SDE solver can be found here and the loop here.

For general usage

Please refer to the original code.
