Title: The GAN Landscape: Losses, Architectures, Regularization, and Normalization,
Abstract: Generative adversarial networks (GANs) are a class of deep generative models
which aim to learn a target distribution in an unsupervised fashion. While they
were successfully applied to many problems, training a GAN is a notoriously
challenging task and requires a significant amount of hyperparameter tuning,
neural architecture engineering, and a non-trivial amount of "tricks". The
success in many practical applications coupled with the lack of a measure to
quantify the failure modes of GANs resulted in a plethora of proposed losses,
regularization and normalization schemes, and neural architectures. In this
work we take a sober view of the current state of GANs from a practical
perspective. We reproduce the current state of the art and go beyond fairly
exploring the GAN landscape. We discuss common pitfalls and reproducibility
issues, open-source our code on Github, and provide pre-trained models on
TensorFlow Hub.
