The MNSIT dataset is a database of handwritten digits, and contains 60,000 training examples and 10,000 testing examples:
from tensorflow.examples.tutorials.mnist import input_data
mnist = input_data.read_data_sets("MNIST_data/", one_hot=True)
We will load the image database from MNIST:
import matplotlib.pyplot as plt
im = mnist.train.images[0,:]
label = mnist.train.labels[0,:]
im = im.reshape([28,28])
We can construct a fully connected feed-forward neural network that is one layer deep to complete the example.
