I am new to GAN. And recently read a paper about how to implement GAN in recommender system here



I have a question in the paper.



The Eq (20) in the paper should be the discriminator function.



The generator should be the $G_phi$ which is mentioned in the Eq (21) and Eq (22). However, what is definition of $G_phi$ here?



Thanks,

    are you asking in general what is the generative part of a GAN, or are you asking what is the specific network architecture that was used by this paper for their generator?

    @JahKnows I read the paper many times and I can't find the definition of $G_theta$. Do it have some common definition so the authors omits?
