What are Generator/Discriminator yfake/real loss?

[kechan]

This isn't really an issue. I am just new to GAN and I am not sure how these are defined:

Generator yfake loss Generator yreal loss Discriminator yfake loss Discriminator yreal loss

Are these general to GAN, or something specific to this framework? Would like to know the best source to read up on these.

Thanks.

In gans Generator yreal loss does not exists ... it is a contradiction ...

I would like to know also
