An Overview of Diffusion-GAN
Diffusion-GAN is a GAN framework that uses a forward diffusion chain to generate Gaussian-mixture distributed instance noise.

Overcoming the ineffectiveness of adding instance noise
Forward Diffusion Chain
Diffusion-GAN uses a forward diffusion chain to generate Gaussian-mixture distributed instance noise for GAN training.

Authors establish the theoretical basis for the consistency
True Data Distribution
Discriminator's timestep-dependent strategy guides the generator to match the true data distribution.

Diffusion-GAN outperforms strong GAN models
State of the Art GANs
Diffusion-GAN outperforms strong GAN models on different datasets by producing more realistic images.
