Understanding Diffusion Models

Diffusion models are a class of generative models that learn to create data by iteratively adding and removing noise. The process involves two main phases:

1. Forward Diffusion Process: Gradually adds noise to the training data, effectively destroying its structure over several steps.

2. Reverse Diffusion Process: Learns to invert the noising process, reconstructing the data from the noisy inputs.

By mastering this denoising procedure, diffusion models can generate new, realistic data samples from random noise inputs.
