Abstract:The variation of the convergence timetau, as a function of the storage capacityagr is studied numerically for systems ranging in size fromN=1000 toN=16,000 neurons.tau is found to increase liketausimexp–A(agrcagr)] as one nears the critical storage capacityagr c =0.142=0.002.
Keywords:Hopfield model  neural networks  spin glasses  relaxation time
