Fig. 3: The reconstruction results of different datasets.
From: Neural encoding with unsupervised spiking convolutional neural network
a The reconstructions of different handwritten characters (B, R, A, I, N, and S). The images in the first row are the presented images (ground truth), and the images in the second to fourth rows are the reconstruction results of the 3 subjects. b The reconstructions of the same character with different writing styles. c The reconstructions of handwritten digits. The handwritten digit images are adapted from the MNIST database (http://yann.lecun.com/exdb/mnist/) with permission. d The reconstructions of natural images. e Examples of prior images with the highest likelihoods of the colorful natural image datasets. The colorful natural images in d and e are adapted from the ImageNet database52 with permission.
