おすすめの解答：D 解答を投票する
A Diffusion Model (or Denoising Diffusion Probabilistic Model) is a specific class of generative AI model that is best known for its ability to create highly realistic images (e.g., Google's Imagen and Stable Diffusion are based on this architecture).
The core mechanism of a diffusion model is a two-step process:
Forward Diffusion (Adding Noise): It learns how to gradually corrupt data (like an image) by adding random noise until the original content is completely indistinguishable. Reverse Diffusion (Denoising): It then learns to reverse this process--to gradually remove the noise--starting from a random noise pattern and iteratively refining it, guided by a text prompt, until a clear, coherent, and high-quality piece of content (an image or video) is generated. Option D accurately captures this mechanism: the model starts with pure noise and generates the final structured data (the image) by refining that noise.
