  This paper introduces a new interpretation of the Variational Autoencoder
framework by taking a fully geometric point of view. We argue that vanilla VAE
models unveil naturally a Riemannian structure in their latent space and that
taking into consideration those geometrical aspects can lead to better
interpolations and an improved generation procedure. This new proposed sampling
method consists in sampling from the uniform distribution deriving
intrinsically from the learned Riemannian latent space and we show that using
this scheme can make a vanilla VAE competitive and even better than more
advanced versions on several benchmark datasets. Since generative models are
known to be sensitive to the number of training samples we also stress the
method's robustness in the low data regime.
