Training auxiliary network. (a) The original Hopfield network can reliably retrieve 20 stored memories. Connectivity matrix . (b) An auxiliary network is sparsely connected to the original network. Connectivity matrix . (c) The auxiliary network is calibrated to generate auxiliary patterns for the original memories for prevention purposes. The connectivity matrix moves from state to . (d) The auxiliary network connects back to the original network. Connectivity matrix = .
