Query: MaGNET: Uniform Sampling from Deep Generative Network Manifolds Without
  Retraining   Deep Generative Networks (DGNs) are extensively employed in Generative
Adversarial Networks (GANs), Variational Autoencoders (VAEs), and their
variants to approximate the data manifold and distribution. However, training
samples are often distributed in a non-uniform fashion on the manifold, due to
costs or convenience of collection. For example, the CelebA dataset contains a
large fraction of smiling faces. These inconsistencies will be reproduced when
sampling from the trained DGN, which is not always preferred, e.g., for
fairness or data augmentation. In response, we develop MaGNET, a novel and
theoretically motivated latent space sampler for any pre-trained DGN, that
produces samples uniformly distributed on the learned manifold. We perform a
range of experiments on various datasets and DGNs, e.g., for the
state-of-the-art StyleGAN2 trained on FFHQ dataset, uniform sampling via MaGNET
increases distribution precision and recall by 4.1\% \& 3.0\% and decreases
gender bias by 41.2\%, without requiring labels or retraining. As uniform
distribution does not imply uniform semantic distribution, we also explore
separately how semantic attributes of generated samples vary under MaGNET
sampling.
