Self-Attention Generative Adversarial Networks

Zhang, Han, Goodfellow, Ian, Metaxas, Dimitris et al.

Understand

In this paper, we propose the Self-Attention Generative Adversarial Network (SAGAN) which allows attention-driven, long-range dependency modeling for image generation tasks.

  • Traditional convolutional GANs generate high-resolution details as a function of only spatially local points in lower-resolution feature maps.
  • In SAGAN, details can be generated using cues from all feature locations.
  • Moreover, the discriminator can check that highly detailed features in distant portions of the image are consistent with each other.
