Questions and Answers

What is the primary goal of the generator in a GAN?

  • To update the parameters of the discriminator
  • To classify the input data as real or fake
  • To distinguish between real and fake samples
  • To create samples that are as realistic as possible to fool the discriminator (correct)

What is the condition under which the training of a GAN is stopped?

  • When the generator is unable to generate new samples
  • When the discriminator is able to distinguish between fake and real samples with 100% accuracy
  • When the generator is able to fool the discriminator
  • When the discriminator is unable to distinguish between fake and real samples (correct)

What is the output of the discriminator in a GAN?

  • A probabilistic value in the interval (0,1) (correct)
  • A continuous value indicating the degree of realism
  • A binary label indicating real or fake
  • A categorical label indicating real or fake
