Gan loss tiny, discriminator loss huge?
I can't find the problem in my code - I'm training a GAN and the gan loss and discriminator loss are very low, 0.04 and it seems like it's converging well but a - the pictures don't look very good but the actual problem is that, b - somehow when I…

How to create a loss-function for an unsupervised-learning model, where the ouput resembles the direct input for a game agent?
I'm trying to setup a deep neuronal network, which predicts the next move for a game agent to navigate a world. To control the game agent it takes two float inputs. The first one controls the speed (0.0 = stop/do not move, 1.0 = max. speed). The…

how to find surrogate of a non convex function
I am doing learning to rank.I have found that some of the loss functions for example 0/1 loss can not be directly minimized being either non-convex or discontinuous etc.this is true in case of other loss functions also.
So the researchers use…

Combine generator loss with GAN loss in Generative Adversarial Network
I'm now trying to implement GAN in keras.
I want to use both the GAN loss and the generator loss at the same time when I train the network.
Because I've found from some papers that this might contribute to some performance gain.
It is a little bit…
