Official code for Score-Based Generative Modeling through Stochastic Differential Equations (ICLR 2021, Oral)

40
/ 100
Emerging

Unifies score-based generative models through continuous-time SDEs, enabling unified training of NCSN, NCSNv2, DDPM variants, and new NCSN++/DDPM++ architectures. Supports exact likelihood computation, latent code manipulation, and conditional generation (inpainting, colorization, class-conditional) through flexible Predictor-Corrector sampling. Implemented in JAX with modular abstractions for SDEs, predictors, and correctors, allowing straightforward extensions while maintaining compatibility across sampling and evaluation methods.
