WebJul 11, 2024 · GAN models are known for potentially unstable training and less diversity in generation due to their adversarial training nature. VAE relies on a surrogate loss. Flow models have to use specialized architectures to construct reversible transform. Diffusion models are inspired by non-equilibrium thermodynamics. WebThis paper shows for the first time, how a non-GAN model, a DDPM, can be improved to overtake GANs at standard evaluation metrics for image generation. The produced samples look amazing and other than GANs, the new model has a formal probabilistic foundation. Is there a future for GANs or are Diffusion Models going to overtake them for good ...
WebNow though, a new king might have arrived - diffusion models. Using several tactical upgrades the team at OpenAI managed to create a guided diffusion model that outperforms state-of-the-art GANs on unstructured datasets such as ImageNet at up to 512x512 resolution. WebDiffusion models have recently been shown to generate high-quality synthetic images, especially when paired with a guidance technique to trade off diversity for fidelity. We explore diffusion models for the problem of text-conditional image synthesis and compare two different guidance strategies: CLIP guidance and classifier-free guidance. We find …

WebAfter about seven days of training*, the GAN achieved an FID of 40.2, while the diffusion model achieved 31.3, meaning that its images match the distribution of real images better. This corroborates what we see in the images above. (* Each model was trained for seven days on an NVIDIA A100 GPU.)
