MNIST 手写数字图像数据集

MNIST数据集是一个手写阿拉伯数字图像识别数据集，图片分辨率为 20x20 灰度图图片，包含‘0 - 9’ 十组手写手写阿拉伯数字的图片。其中，训练样本 60000 ，测试样本 10000，数据为图片的像素点值，作者已经对数据集进行了压缩。 Overview The MNIST database of handwritten digits, has a training set of 60,000 examples, and a test set of 10,000 examples. It is a subset of a larger set available from NIST. The digits have been size-normalized and centered in a fixed-size image. It is a good database for people who want to try learning techniques and pattern recognition methods on real-world data whil
