Query: Metrics for Deep Generative Models   Neural samplers such as variational autoencoders (VAEs) or generative
adversarial networks (GANs) approximate distributions by transforming samples
from a simple random source---the latent space---to samples from a more complex
distribution represented by a dataset. While the manifold hypothesis implies
that the density induced by a dataset contains large regions of low density,
the training criterions of VAEs and GANs will make the latent space densely
covered. Consequently points that are separated by low-density regions in
observation space will be pushed together in latent space, making stationary
distances poor proxies for similarity. We transfer ideas from Riemannian
geometry to this setting, letting the distance between two points be the
shortest path on a Riemannian manifold induced by the transformation. The
method yields a principled distance measure, provides a tool for visual
inspection of deep generative models, and an alternative to linear
interpolation in latent space. In addition, it can be applied for robot
movement generalization using previously learned skills. The method is
evaluated on a synthetic dataset with known ground truth; on a simulated robot
arm dataset; on human motion capture data; and on a generative model of
handwritten digits.
