Perceptual learning demonstration. a The influence of different laser pulse numbers and powers on the image recognition accuracies. The wavelength of the stimulation laser pulse is 530 nm. b Image recognition accuracies during the forgetting process. The synapses were stimulated with 530 nm laser pulses with different numbers. c The relationship between the accuracies and the laser pulses with different frequencies. d The accuracies change during the learning–forgetting–relearning process. The synapses were stimulated with 1.90 W/cm² 530 nm laser pulses. e The confusion matrix of the test image after 17-second learning. The accuracy is 97.08 %. f The confusion matrix of t the test image after 9-second relearning. The accuracy is 97.01 %
