Hippocampally-Dependent Consolidation in a Hierarchical
Model of Neocortex

Abstract
In memory consolidation, declarative memories which initially require
the hippocampus for their recall, ultimately become independent of
it. Consolidation has been the focus of numerous experimental and
qualitative modeling studies, but only little quantitative
exploration. We present a consolidation model in which hierarchical
connections in the cortex, that initially instantiate purely semantic
information acquired through probabilistic unsupervised learning, come
to instantiate episodic information as well. The hippocampus is
responsible for helping complete partial input patterns before
consolidation is complete, while also training the cortex to perform
appropriate completion by itself.
