USPS Dataset
Note: This dataset (scaled to [-1:1] instead of [0:2]) also appears in the book "The elements of statistical learning" by Hastie, Tibshirani and Friedman (Springer, 2001). It is available from the corresponding website here with the name "ZIP code". The dataset consists of a training set (usps_train.jf, 1.4M) with 7291 images and a test set (usps_test.jf, 390k) with 2007 images. The ".jf" format i
