mnist

MNIST数据集来自美国国家标准与技术研究所, National Institute of Standards and Technology (NIST)。训练集（training set）由来自250个不同人手写的数字构成，其中50%是高中学生，50%来自人口普查局（the Census Bureau）的工作人员。测试集（test set）也是同样比例的手写数字数据，但保证了测试集和训练集的作者集不相交。

The MNIST dataset originates from the National Institute of Standards and Technology (NIST). The training set consists of handwritten digit samples from 250 distinct individuals, with 50% being high school students and the other 50% being staff of the Census Bureau. The test set is composed of handwritten digit data with the same demographic proportion, and it is guaranteed that the sets of contributors for the training and test sets are completely disjoint.
