  In this essay we conjecture that quantum fields such as the Higgs field is
related to a restricted Boltzmann machine for deep neural networks. An
accelerating Rindler observer in a flat spacetime sees the quantum fields
having a thermal distribution from the quantum entanglement, and a
renormalization group process for the thermal fields on a lattice is similar to
a deep learning algorithm.
  This correspondence can be generalized for the KMS states of quantum fields
in a curved spacetime like a black hole.
