Play an AI-generated podcast conversation about this lesson

What is the purpose of Generative Models in unsupervised learning?

To model the underlying probability distribution of the data to generate new samples that look like the training data.

What is the role of the Generator in a GAN architecture?

To take random noise as input and transform it into data samples that look like real data.

How does the Discriminator contribute to the training process in a GAN?

It evaluates the authenticity of a given data sample and learns to distinguish between real and fake data.

What is the objective of the training process in a GAN?

To involve an adversarial game between the Generator and Discriminator to improve the generation of realistic data. Signup and view all the answers
