Code Stable Diffusion from Scratch: A Complete Tutorial

TLDRLearn how to code stable diffusion from scratch using PyTorch. This tutorial covers the math behind diffusion models, text-to-image generation, image-to-image manipulation, and inpainting.

Key insights

👩‍💻Stable diffusion is a generative model that learns a probability distribution of data and can generate new instances.

🧠The model includes a forward process (adding noise) and a reverse process (removing noise) that can be trained using neural networks.

🔑Training the reverse process involves learning parameters to denoise images by predicting the amount of noise present.

🏞️Stable diffusion can be used for text-to-image generation, image-to-image manipulation, and inpainting.

💡To control the generative process, a prompt or conditioning signal can be introduced during the noise removal chain.
