Currently, I am going through Geometry of the Restricted Boltzmann Machine by Cueto et al.
In this paper (in the abstract, multiple places in Section 1, etc.), the authors use the concept of the identification of restricted Boltzmann machine.
What does 'identification' mean in this context? Thanks.
"Identifiability" means you can find a unique solution that generates your observations. Unidentifiable models have multiple solutions that are equivalent.
