Preventing Neurodegenerative Memory Loss in Hopfield Neuronal Networks Using Cerebral Organoids or External Microelectronics

Figure 5

Failure rates for Hopfield networks encoded with an optimal memory set. Plots show the times (%) for which the original network fails to retrieve a memory as a function of the density of connections in linking the auxiliary to the original network and the amount of initial noise in the memory cue. At higher damage levels in , the auxiliary network pays off and helps decrease the failure rate. The larger auxiliary network ( nodes) also outperforms the smaller one ( nodes) at high damage levels. At low damage levels in (0%–20% damage), the auxiliary networks have little effect on original memory retrieval.
