Hands-On Machine Learning on Google Cloud Platform

Load data

This is a database of handwritten digits consisting of 60,000 28 x 28 grayscale images of the 10 digits, along with a test set of 10,000 images. This dataset is already available in the Keras library. The following diagram shows a sample of images of 0-8 from the MNIST dataset:

As always, we will analyze the code line by line. In the first part of the code, we import the libraries we will use later:

from keras.layers import Input, Densefrom keras.models import Model

This code imports the following function:

• The Input function is used to instantiate a Keras tensor. A Keras tensor is a tensor object from the underlying backend (Theano, ...
