The following is a simple, well-known method for enforcing invertibility:
With pattern ,
a reconstructor module receives the concatenation of all
as an input
and is trained to emit as an output the reconstruction
of the external input .
The basic structure is an auto encoder.
The auto encoder's objective function, to be minimized, is defined as
