CLIP-GEN: Language-Free Training of a Text-to-Image Generator with CLIP

Wang, Zihao, Liu, Wei, He, Qian et al.

Understand

Training a text-to-image generator in the general domain (e.g., Dall.e, CogView) requires huge amounts of paired text-image data, which is too expensive to collect.

  • In this paper, we propose a self-supervised scheme named as CLIP-GEN for general text-to-image generation with the language-image priors extracted with a pre-trained CLIP model.
  • In our approach, we only require a set of unlabeled images in the general domain to train a text-to-image generator.
  • Specifically, given an image without text labels, we first extract the embedding of the image in the united language-vision embedding space with the image encoder of CLIP.
