Learning target of Denoising Diffusion Probabilistic Model

I am trying to understand the learning target of DDPM. Trying to understand $D_{KL}(q(x_{1:T}|x_0)||p_\theta(x_{1:T}|x_0)$ in following line. $$ -\log p_\theta(x_0) <= -\log p_\theta(x_0) + D_{KL}(...

How many parameters are necessary before stable diffusion "works"?

Stable diffusion is essentially removing entropy from noisy images. If you have $n$ latent dimensions, and add Gaussian noise independently to each dimension, then the added entropy is on the order of ...

How to generate synthetic feature instead of synthetic image using Diffusion-based generative Model?

Is it possible to pass some extracted features from the pre-trained ResNet model to a diffusion model for training and further generate synthetic features instead of images like GAN or VAE? P.S. I ...
