- Euclidean distance between predicted and ground truth pixels is not a good method of judging similarity because it yields blurry images.
- GANs learn a loss function rather than using an existing one.
- GANs learn a loss that tries to classify if the output image is real or fake, while simultaneously training a generative model to minimize this loss.
- Conditional GANs (cGANs) learn a mapping from observed image
xand random noise vectorztoy:y = f(x, z) - The generator
Gis trained to produce outputs that cannot be distinguished from "real" images by an adversarially trained discrimintor,Dwhich is trained to do as well as possible at detecting the generator's "fakes". - The discriminator
D, learns to classify between real and synthesized pairs. The generator learns to fool the discriminator. - Unlike an unconditional GAN, both th
