MNIST handwritten data set is a set of digital data, each picture is 0 to 9, a single number, such as the following several:

 
 

MNIST database sources is a mixture of the two databases, one from the Census Bureau employees (SD-3), from a high-school students (SD-1); training sample has 60,000, 10,000 test samples.
