MNIST Images of Digit 3

digit3 contains 2000 images from the famous MNIST dataset of digit 3. Each element of the list is an image represented as an \((28\times 28)\) matrix that sums to 1. This normalization is conventional and it does not hurt its visualization via a basic image() function.

Usage

data(digit3)

Format

a length-\(2000\) named list "digit3" of \((28\times 28)\) matrices.
