On Leveraging Pretrained GANs for Generation with Limited Data

Zhao, Miaoyun, Cong, Yulai, Carin, Lawrence

Understand

Recent work has shown generative adversarial networks (GANs) can generate highly realistic images, that are often indistinguishable (by humans) from real images.

  • Most images so generated are not contained in the training dataset, suggesting potential for augmenting training sets with GAN-generated data.
  • While this scenario is of particular relevance when there are limited data available, there is still the issue of training the GAN itself based on that limited data.
  • To facilitate this, we leverage existing GAN models pretrained on large-scale datasets (like ImageNet) to introduce additional knowledge (which may not exist within the limited data), following the concept of transfer learning.
