Question 11

+2 marksOne or more correct options

Which among the following is true for a denoising diffusion probabilistic model (DDPM)?

Select all that apply.

  1. A

    The forward process in DDPM gradually adds noise to the input.

  2. B

    The forward process in DDPM learns to generate data by denoising.

  3. C

    In the reverse process of DDPM, we stack the VAE decoders.

  4. D

    In the reverse process of DDPM, we stack the VAE encoders.
