Legendre Equivalences of Spherical Boltzmann Machines
arXiv:1910.14559 · doi:10.1088/1751-8121/ab6b92
Abstract
We study either fully visible and restricted Boltzmann machines with sub-Gaussian random weights and spherical or Gaussian priors. We prove the free energies of the spherical and Gaussian models are related by a Legendre transformation. Incidentally our analysis brings also a new purely variational derivation of the free energy of the spherical models.
