The training process was stopped when the mean loss value on the validation set did not decrease for one epoch (see Additional file 1: Fig. S1b). During the adversarial training process, the generator was tuned with a learning rate of 0.0001.

WebThe adversarial loss pushes the solution to the natural image manifold using a discriminator network that is trained to differentiate between the super-resolved images and original photo-realistic images. In addition, the authors use a content loss motivated by perceptual similarity instead of similarity in pixel space. WebFor the adversarial generator we have LG = − 1 m ∑m k=1 log(D(z))LG = −m1 k=1∑m log(D(z)) ( Plot) By looking at the equations and the plots you should convince yourself that the loss defined this way will enforce the discriminator to be able to recognize fake samples while will push the generator to fool the discriminator.
