Figure | Linear optical potentiation/electrical depression behaviors and high-accuracy image classification functions. a, Eight cycles of optical potentiation/electrical depression behaviors. b, Typical cycle of optical potentiation/electrical depression behaviors under consecutive training pulses, presenting a high linearity of weight updating. c, Schematic illustration of NVS for the application of fingerprint classification. d, The fingerprint images with different-level Gaussian noise, whose standard deviation (std) ranges from 0 to 0.15. e, Recognition accuracy evolution with training epochs for the NVS with different noise ratios. The classification output results depicted in the confusion matrixes f, without and g with Gaussian noise (std is set as 0.1).
