How Generative Adversarial Networks and Their Variants Work: An Overview
It serves as a tutorial for researchers familiar with but not deeply comprehending GANs, offering incremental insights by summarizing existing methods and variants.
This paper provides an overview of Generative Adversarial Networks (GANs) and their variants, explaining their operation, objective functions, and applications in fields like image synthesis and domain adaptation, without presenting new experimental results or numbers.
Generative Adversarial Networks (GAN) have received wide attention in the machine learning field for their potential to learn high-dimensional, complex real data distribution. Specifically, they do not rely on any assumptions about the distribution and can generate real-like samples from latent space in a simple manner. This powerful property leads GAN to be applied to various applications such as image synthesis, image attribute editing, image translation, domain adaptation and other academic fields. In this paper, we aim to discuss the details of GAN for those readers who are familiar with, but do not comprehend GAN deeply or who wish to view GAN from various perspectives. In addition, we explain how GAN operates and the fundamental meaning of various objective functions that have been suggested recently. We then focus on how the GAN can be combined with an autoencoder framework. Finally, we enumerate the GAN variants that are applied to various tasks and other fields for those who are interested in exploiting GAN for their research.
