Self-Attention Generative Adversarial Networks

Self-Attention Generative Adversarial NetworksHan Zhang1 2 Ian Goodfellow2 Dimitris Metaxas1 Augustus Odena2 AbstractIn this paper, we propose the Self-Attention Gen-erative Adversarial network (SAGAN) whichallows attention -driven, long-range dependencymodeling for image generation tasks. Traditionalconvolutional GANs generate high-resolution de-tails as a function of only spatially local pointsin lower-resolution feature maps. In SAGAN, de-tails can be generated using cues from all featurelocations. Moreover, the discriminator can checkthat highly detailed features in distant portionsof the image are consistent with each other. Fur-thermore, recent work has shown that generatorconditioning affects GAN performance. Leverag-ing this insight, we apply spectral normalizationto the GAN generator and find that this improvestraining dynamics.

Self-Attention Generative Adversarial Networks Figure 1. The proposed SAGAN generates images by leveraging complementary features in distant portions of the image rather than local regions of fixed shape to generate consistent objects/scenarios. In each row, the first image shows five representative query locations with color coded dots.
