#' @format A list with four items: Xtrain is a training set matrix with 6000 rows (samples) and 784 columns (features),
#' Xtrain is an integer array of corresponding training class labels, Xtest is a test set matrix of 10000 rows and 784
#' columns, and Ytest is the corresponding class labels. Rows in Xtrain and Xtest correspond to different images of digits,
#' and columns correspond to the pixel intensities in each image, obtained by flattening the image pixels in column-major ordering.
