RPGAN: GANs Interpretability via Random Routing [article]

Andrey Voynov, Artem Babenko
2020 arXiv   pre-print
In this paper, we introduce Random Path Generative Adversarial Network (RPGAN) -- an alternative design of GANs that can serve as a tool for generative model analysis.  ...  While the latent space of a typical GAN consists of input vectors, randomly sampled from the standard Gaussian distribution, the latent space of RPGAN consists of random paths in a generator network.  ...  RP-GAN is based on an alternative generator design that allows natural interpretation of different layers via using random routing as a source of stochasticity.  ...
