WebJan 29, 2024 · So I´m training a CycleGAN for image-to-image transfer. The problem is: while the discriminator losses decrease, and are very small now, the generator losses don't decrease at all. The generator loss is: 1 * discriminator-loss + 5 * identity-loss + … Web2 days ago · However, training a GAN using the conventional loss function is unstable and frequently fails to achieve Nash equilibrium, which is the global optimum of the generator and discriminator. Numerous techniques have been developed to address this shortcoming of typical GANs, including Wasserstein GANs [ 35 ] and spectral normalization (SN) [ 36 ]. lavatory ada shroudWebBack-propagating this loss signal through the discriminator and optimizing its weights means that whenever the discriminator is shown a fake image, we want it to predict a value very close to 0 which is the label of a fake image.Unlike steps one and two where we train the discriminator only, step three attempts to train the generator. lavatory and sink
