Generative Query Network

  • We have K images for scene i: \(\mathbf{x}^k_i\) taken from 2D viewpoints \(\mathbf{v}^k_i\)
  • A representation network creates a neural representation \(\mathbf{r}\).
  • The generation network predicts the scene from viewpoints \(\mathbf{v}^q\) and random noise \(\mathbf{z}\).
