LSGM trains a score-based generative model (a.k.a. a denoising diffusion model) in the latent space of a variational autoencoder. It currently achieves state-of-the-art generative performance on several image datasets.RequirementsLSGM is built in Python 3.8 using PyTorch 1.8.0. Please use the...
Diffusers allows you to test score sde based models in PyTorch in just a couple lines of code.You can install diffusers as follows:pip install diffusers torch accelerate And then try out the models with just a couple lines of code:from diffusers import DiffusionPipeline model_id = "google/...

When comparing PSSAM-GAN with DCN-PD and TARNet for the Jobs dataset, we followed the original papers’ train/test split setup for continuity in interpreting the results, noting that some of the original procedures have been re-coded here in Pytorch. For the IHDP dataset, we trained the m...

Suppose we are trying to evaluate a trained generative model G that encodes a distribution pg over images 𝐱^. We can sample from pg as many times as we would like, but do not assume that we can directly evaluate pg. The Inception Score is one way to evaluate such a model (Salimans...
