Diffusion Models
Diffusion models generate images (and audio/video) by learning to reverse a noising process: training corrupts data into noise step by step, and the model learns to denoise, so at generation it starts from pure noise and iteratively denoises into a sample. Text conditioning (via cross-attention to text embeddings) steers what gets generated, and latent diffusion denoises in a compressed space for efficiency. Applied-AI interviews probe it because it is the basis of image generation systems and explains their cost, latency, and the role of guidance.
