Diffusion Model
The technology behind AI image generation
Definition
Diffusion models are a class of generative AI that learns to create images by learning to reverse a process of adding noise to training images. At generation time, they start from random noise and iteratively denoise it to produce a coherent image guided by a text prompt. Stable Diffusion, DALL-E, and Midjourney all use diffusion-based approaches.
