Previously, we explored the diffusion model's noise-adding and denoising process and understood the basics of Transformers.

I also hinted earlier about using a UNet network to predict noise at each step.

Today, I'll explain the core concepts of UNet. We'll focus on answering these three questions:

• How does the UNet model work?

• What makes the UNet structure in various AI art models unique?

• How can UNet be combined with Transformers?

By grasping these concepts, you'll be able to modify the noise prediction model in your work and lay a solid foundation for our hands-on training in diffusion models.
