Stable Diffusion is a principle in machine learning, particularly in the realm of generative adversarial networks (GANs), that focuses on generating high-quality, diverse, and coherent data samples. Unlike traditional GANs that may suffer from issues like mode collapse, where the generator produces limited varieties of samples, Stable Diffusion aims to maintain a stable and controlled diffusion process throughout the generation.
Principle Explanation:
The core idea behind Stable Diffusion is to gradually transform a simple, random noise distribution into a complex, target data distribution. This is achieved through a series of diffusion steps, where each step adds a controlled amount of noise to the data and then learns to reverse this process. By iteratively refining the transformation, the model can generate highly realistic samples.
Example:
Imagine generating a photograph of a cat. With Stable Diffusion, the process starts with a completely random noise image. Through multiple diffusion steps, the model adds structured noise that gradually takes the shape of a cat. Each step is carefully controlled to ensure the transformation is smooth and realistic, resulting in a high-quality cat image at the end.
