Question 12

+2 marksOne correct option

You've been training your GAN for 100 epochs. You notice two things:

  1. The Generator loss (g_loss) is very low and stable, and the Discriminator loss (d_loss) is high and stable.
  2. When you inspect the saved images, the Generator is producing the exact same (or very similar) image of a single "ankle boot" for every latent vector z you input.

What is this classic GAN failure mode called?

  1. A

    Vanishing Gradients

  2. B

    Mode Collapse

  3. C

    Overfitting

  4. D

    Discriminator Saturation
