  • Abstract: Feature representation for clustering purposes consists in building an explicit or implicit mapping of the input space onto a feature space that is easier to cluster or classify. This paper relies upon an adversarial auto-encoder as a means of building a code space of low dimensionality suitable for clustering. We impose a tunable Gaussian mixture prior over that space allowing for a simultaneous optimization scheme. We arrive at competitive unsupervised classification results on hand-written digits images (MNIST) that is customarily classified within a supervised framework.
  • TL;DR: We simultaneously train both an auto-encoder and a Gaussian mixture model for clustering in an adversarial fashion
