Definition
Denoising
Denoising is the process of removing noise from a signal (like a digital image or audio track). In generative AI, denoising autoencoders and diffusion networks are trained to reconstruct clean inputs from intentionally corrupted variants.
Frequently Asked Questions
How do diffusion models utilize denoising?▼
They learn the mathematical reverse steps to subtract noise iteratively, starting from random gaussian noise to reveal a clean image.
What is a denoising score matching objective?▼
A training framework that teaches a model to predict the vector field pointing from a noisy sample toward the true data manifold.
