This GAN being trained with CelebA dataset doesn't seem to mode collapse, discriminator is not really over confident, and yet the quality is stuck on these rough Picasso-like generator images. Using Leaky-ReLU, strided conv instead of maxpool, and dampened truths helped a little, but still no better than this. bramley cemetery rotherham

WebNov 13, 2024 · Generally GANs don’t converge well. A typical GAN loss should be something where G loss log (D (G (z)) maximizes and D loss log (D (x))+log (1-D (G (z)) minimizes. But that’s not the scenario all the time. Most of the time the discriminator gets fooled easily by the generator. To avoid this: Update the discriminator more often than … WebMay 12, 2024 · In simple words, we can think of failure in convergence as a condition where we can’t find the convergence point in the learning curve of a neural network.
