  • Discrete Distribution Networks (DDN) introduced as a novel generative model with hierarchical discrete distributions.
  • DDN fits target distributions by generating multiple discrete sample points, refining outputs layer by layer.
  • Unique properties of DDN include general zero-shot conditional generation and 1D latent representation.
  • Experiments demonstrate DDN's efficacy on datasets like CIFAR-10 and FFHQ.
  • DDN supports zero-shot conditional generation across non-pixel domains without relying on gradients.
  • Training phase shows generated images become increasingly similar to training images as network depth increases.
  • Split-and-Prune strategy reduces KL divergence more effectively than Gradient Descent alone.
  • Future research directions include hyperparameter tuning, scaling to ImageNet, and applying DDN to language modeling.
  • DDN's GPU memory requirements are slightly higher than conventional GANs but manageable.
  • DDN avoids mode collapse by selecting outputs most similar to GT and using L2 loss.
