WebJan 7, 2024 · In a GAN setup, two differentiable functions, represented by neural networks, are locked in a game. The two players (the generator and the discriminator) have different roles in this framework. The generator tries to produce data that come from some probability distribution. That would be you trying to reproduce the party’s tickets. WebJun 28, 2024 · The discriminator’s role in GAN is to solve a binary classification problem that learns to discriminate between a real and a fake image. It does this by: Predicting whether the observation is generated by the generator (fake), or from the original data distribution (real). While doing so, it learns a set of parameters or weights (theta).
