Schematic illustration of the network structure. Each learning data is the average of 100 images from the MNIST data base. The testing data are digitised from the MNIST test data base according to Eq. (5). For learning, the input neurons encode the pixel intensity into a switching probability of the correspondent synaptic weights according to a supervised assignment of the patterns to the receptive fields of the output neurons. For testing, the input neurons map the digitised images to the receptive fields. The output neurons are perceptrons which get activated by the testing data assigning the test images to the respective patterns. The activation function [see Eq. (6)] is depicted for different slopes k.
