""" Basis class EnergyOperator.
The NIFTy EnergyOperator class derives from the Operator class
.
Operator which has a scalar domain as target domain
.
An EnergyOperators transforms a field into a scalar, the information energy
of the field. Typically, an EnergyOperators is an information Hamiltonian
( = negative log probability) or a Gibbs free energy ( = averaged
Hamiltonian), aka Kullbach-Leibler divergence.
An EnergyOperator returns a scalar for a field, and a linearized
Typical usage in IFT:
as an information Hamiltonian ( = negative log probability)
or as a Gibbs free energy ( = averaged Hamiltonian), aka Kullbach-Leibler
divergence.
An EnergyOperator can also provide its gradient as an EndomorphicOperator
that converts a field into a field, the gradient of the Hamiltonian at the
