Aging in the retrieval phase of the Hopfield model. (English) Zbl 0984.92501
Summary: In this work we present a numerical study of the complex dynamical behavior of the Hopfield model within its retrieval phase. We find that the spin glass solutions that coexist with the retrieval attractors display a rich out of equilibrium dynamics suggesting the presence of a very intricate phase space structure, which resembles that of the Sherrington-Kirkpatrick model.
