### What is being optimized with WGAN loss? Is the generator maximizing or minimizing the critic value?

I think I understand what's happening with the loss functions now. Notation: D = discriminator/critic G = generator D(x) - Critic score on real data D(G(z)) - Critic score on fake data ∇_D - Critic ...

### What is the meaning of $p_{\text {data }}(y)$ in the CycleGAN?

I interpret $p_{data}(y)$ as the empirical probability of seeing an image $y$ in the training data. For example, in a typical training run, each training image is shown to the network the same number ...

### What is the domain of the discriminator of a GAN?

Let me try to explain this way, comment if you think it's incorrect. Assume a simple linear function, $y=f(x)=ax+b$ where $a \in \mathbb{R}^*$ and $b\in \mathbb{R}$, each value of $y$ is unique, which ...

### What is the domain of the discriminator of a GAN?

Formally, for an input $x$, $D(x)$ gives you the probability of $x$ being real. In this sense $D:\mathcal{X}\rightarrow [0,1]$, where $\mathcal{X}$ is the input space. That said, the output of the ...
