a Schematic illustration of the MLP neural network for an MNIST pattern recognition test. b Learning accuracy of the neuromorphic system with the analog memristors after 100 epochs of training. The nonlinear synapse updates in Table 1 are considered in the simulation. The number of conductance states for the analog memristors is varied from 50 to 100, 200, and 500.
