Questions and Answers

What is the purpose of sampling random Gaussian noise in the image generation process?

  • To define how much steps of noise (T) to take for generating the new images (correct)
  • To predict the whole noise present in the image
  • To project the input into a smaller latent space and apply the diffusion there
  • To apply the diffusion process directly on a high-dimensional input
  • What does the Diffusion Model do in each step of noise?

  • Samples random Gaussian noise
  • Predicts the whole noise present in the image and removes a fraction of it (correct)
  • Applies the diffusion process directly on a high-dimensional input
  • Projects the input into a smaller latent space and applies the diffusion there
  • What is a characteristic of Latent Diffusion Models?

  • They are SOTA on Image Generation (correct)
  • They predict the whole noise present in the image and remove a fraction of it
  • They apply the diffusion process directly on a high-dimensional input
  • They generate images quickly
  • What is one of the challenges in image generative models that Diffusion models address?
