Generative AI - Diffusion Models

Diffusion Models

A relatively new class of generative models called diffusion models has demonstrated remarkable potential in producing high-fidelity data. Diffusion models produce data through a multi-step process that gradually reduces noise from a noisy input, in contrast to GANs and VAEs, which generate data in a single step.

Principles and Mechanisms

The key principles of diffusion models include:

  • Forward Diffusion Process: Using a series of phases, this method progressively adds Gaussian noise to the data until it is only noise.
  • Reverse Diffusion technique: Using a neural network to gradually denoise the input over a number of stages, this technique reverses the noise addition.

Diffusion models can deliver data with great accuracy and detail thanks to the forward and reverse processes, and progressive denoising aids in the improvement of the generated samples.

Real-World Applications

There are several uses for diffusion models, such as:

  • Image Synthesis: Diffusion models are helpful for tasks like image production and restoration because they can produce incredibly realistic images.
  • Inpainting: These models use the denoising process to fill in the areas of a picture that are missing.
  • Data denoising: Diffusion models work well for applications like picture and audio denoising because they can effectively remove noise from data.
