Query: On the Information Theoretic Distance Measures and Bidirectional
  Helmholtz Machines   By establishing a connection between bi-directional Helmholtz machines and
information theory, we propose a generalized Helmholtz machine. Theoretical and
experimental results show that given \textit{shallow} architectures, the
generalized model outperforms the previous ones substantially.
