What is 'ADM' mean in this paper?

I am an undergrad student in CS, and I have been interested in Generative model recently. I apologize for my ignorance.

I have a question while reading your paper that contributed greatly to the diffusion model. In an experiment comparing FIDs of generated images with other diffusion models, or generative models such as GAN, I thought LDM-1 was ADM (A Diffusion model without classifier guidance in paper: "Diffusion model beat GANs ~~". However, in this experiment, LDM-1 was compared with ADM, and ADM performed better. What is the 'ADM' used in this experiment? Can you give me the name or link of the paper that was presented in which paper?

"Diffusion models beat GANs on image synthesis", I think.

As I mentioned above, at first, I also thought that it is a model introduced in that paper, but In experiment in this paper, LDM-1 is being compared with that ADM. Why aren't they same? Which models were used in LDM-1 and ADM?

ADM - ablated diffusion model

[Harr7y]

LDM: Latent diffusion model -> diffusion occurs at latent representation. ADM: Ablated diffusion model -> diffusion occurs at image level.
