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 qualita(cid:173) tive 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 infor(cid:173) mation as well. The hippocampus is responsible for helping complete partial input patterns before consolidation is complete, while also train(cid:173) ing the cortex to perform appropriate completion by itself.
