Las respuestas y explicaciones aparecen a medida que realiza el cuestionario.

  1. A alto nivel, ¿cómo genera un modelo de difusión una imagen?
    • Comienza a partir de ruido aleatorio y elimina repetidamente el ruido para formar una imagen.
    • Copia la imagen más cercana de su conjunto de entrenamiento.
    • Dibuja formas un trazo a la vez como un humano.
    • Une fotos encontradas en línea.
  2. Where does the original Stable Diffusion v1 pipeline perform its learned denoising work?
    • Only in an unchanged image filename
    • Only in a single scalar with no spatial features
    • Without any learned neural model
    • In an autoencoder latent representation rather than directly over full-resolution pixels
  3. How does text condition the documented original Stable Diffusion v1 denoiser?
    • The prompt only names the output file
    • Each prompt word must be printed literally into every output
    • CLIP text embeddings provide conditioning through cross-attention
    • The model ignores all text information
  4. What does classifier-free guidance combine in the documented sampling formula?
    • Two unrelated image filenames
    • Conditional and unconditional denoising predictions
    • Only the red and blue display channels
    • A guarantee that every increased scale improves quality
  5. Which statement accurately qualifies a change to sampler step count?
    • Every additional step must improve every model’s image
    • Step count never changes any computation
    • A single step guarantees perfect image fidelity
    • Quality and elapsed time depend on the model, sampler and settings; more steps are not universally better
  6. What does the original Stable Diffusion project’s publication of model artifacts enable?
    • Inspection and supported extension under the stated model and license conditions
    • Unrestricted use of every model without any conditions
    • A guarantee that all devices can run every checkpoint
    • Proof that every possible fine-tune is compatible
  7. What additional input type does the cited ControlNet method provide for diffusion generation?
    • Only the final output filename
    • Spatial conditions such as edges, pose or depth
    • A mandatory list of every training image
    • Only an encryption password
  8. With the documented factor-eight spatial downsampling, what latent height and width correspond to a 512-by-512 v1 image?
    • 512 by 512
    • 128 by 128
    • 64 by 64
    • 8 by 8
