– The authors devote significant space to common failure modes (mode collapse, non-convergence) and practical fixes: label smoothing, noise injection, gradient penalties, and hyperparameter tuning.

The key idea behind GANs is to train the generator network to produce synthetic data samples that are indistinguishable from real data samples, while simultaneously training the discriminator network to correctly distinguish between real and synthetic samples. This adversarial process leads to a minimax game between the two networks, where the generator tries to produce more realistic samples and the discriminator tries to correctly classify them. gans in action pdf github

The training process is a continuous feedback loop. The Discriminator learns to detect flaws in the Generator's output, while the Generator modifies its parameters to bypass the Discriminator's scrutiny. Mathematically, this is expressed as a minimax objective function:

The generator uses transpose convolutions (upsampling) to turn a 1D vector of random noise into a 2D image. This adversarial process leads to a minimax game

The Discriminator acts as an art inspector. Its job is a binary classification task: distinguish between authentic data from the training set and synthetic data produced by the Generator. It outputs a probability score between 0 (completely fake) and 1 (completely real). The Minimax Game
