Understanding Generative Adversarial Networks (GANs)

Definition and Core Concepts of GANs

Generative Adversarial Networks, in essence, consist of two neural networks – the Generator and the Discriminator – engaged in a continuous competition. The Generator strives to produce images resembling real ones, while the Discriminator endeavors to distinguish between real and generated images. This adversarial training process results in the Generator creating increasingly realistic outputs.

How GANs Work: Generator and Discriminator

The Generator employs a latent vector to generate images, attempting to fool the Discriminator into believing these are authentic. The Discriminator, in turn, refines its ability to distinguish real from generated images. This iterative process continues until the Generator produces images nearly indistinguishable from real ones, achieving a state of equilibrium.

Training Process of GANs

GANs undergo a unique training process involving back-and-forth learning. The Generator refines its output based on feedback from the Discriminator, and vice versa. This dynamic training approach sets GANs apart, enabling them to learn intricate patterns and nuances, resulting in highly realistic image synthesis.
