What is a diffusion model in simple terms?
A diffusion model is a type of AI that learns to create data by slowly adding noise to it and then learning how to remove that noise step-by-step to get back the original data.

Why do diffusion models add noise to data during training?
They add noise to teach the model how to reverse the process, so it can start from random noise and create new, realistic data by removing noise gradually.

What is the main goal of the reverse diffusion process?
The goal is to start with pure noise and step-by-step remove noise to generate new data that looks like the original training examples.

How is a diffusion model similar to making a blurry photo clear again?
Just like making a blurry photo clear by removing blur step-by-step, a diffusion model removes noise step-by-step to create clear, realistic data.

What does a diffusion model learn to do?
✗ Incorrect
Diffusion models learn to remove noise gradually to generate new data.
Why is noise added during training in diffusion models?
✗ Incorrect
Noise is added so the model learns how to remove it step-by-step.
What is the starting point for generating new data in a diffusion model?
✗ Incorrect
Generation starts from random noise that the model cleans up.
Which of these is a common application of diffusion models?
✗ Incorrect
Diffusion models are widely used to generate images from text prompts.
How does the reverse diffusion process work?
✗ Incorrect
Reverse diffusion removes noise gradually to create new data.
Explain in your own words how a diffusion model generates new data.
Think about how the model learns by reversing noise addition.
