Forward and Reverse Processes
A diffusion system defines a controlled forward process that progressively corrupts data and trains a model to approximate the reverse transformation.

Conditioning allows a generative process to be directed by text, class labels, images, or other signals. The conditioning mechanism determines how strongly external information influences the generated sample.
