Question 16

+4 marksOne or more correct options

Which of the following situations may lead to a mode collapse while training a GAN?

Select all that apply.

  1. A

    A GAN trained on MNIST generates only the digit '3' repeatedly, even though the dataset contains digits 0-9.

  2. B

    GAN generates limited variations of faces with similar expressions despite diverse training data.

  3. C

    The GAN underfits the training data.

  4. D

    The discriminator becomes accurate straightaway after training the GAN on just the first 5 images.
