Dataset Information

Additional Information

The data set consists of images from 153 character fonts. Some fonts were scanned from a variety of devices: hand scanners, desktop scanners or cameras. Other fonts were computer generated. The .zip file contains .csv, comma delimited files, one for each font. Each .csv file has a header row with the data set attribute names. The Handprint images differ slightly from the standard MNIST dataset.
