The D accuracy went constant at 0.5 after 20 epochs, and the G accuracy went up to 1.0, and both losses gradually went down. All metrics did oscillate in the middle of the training but in small amount of deviation. Did my model overfit at epoch 20? | |
Nov 17, 2020 at 11:29 | comment | added | Aray Karjauv | Did you try to generate fake images? Since the main goal of GANs to produce synthetic samples, the main matric will be the quality of generated images. Take a look at this answer. There is a plot of G loss and D loss of DCGAN. We can see that D loss is near 0, whereas G loss has oscillations, but G was able to produce good samples. | |

In other words, I feed real images array into the discriminator model, and it outputs values close to 1.0 . Next, I feed fake images (the one that is generated by the generator) into the discriminator model, and it outputs values close to 0.5 . These happens too often, and it is very predictable.
