This code tries to reproduce the 1989 Yann LeCun et al. paper: Backpropagation Applied to Handwritten Zip Code Recognition. To my knowledge this is the earliest real-world application of a neural net trained with backpropagation (now 33 years ago). run Since we don’t have the exact dataset that was used in the paper, we take MNIST and randomly pick examples from it to generate an approximation of the dataset, which contains only 7291 training and 2007 testing digits, only of […]
