Building a neural network in Keras and TensorFlow

This is the core of this particular set of recipes. Let's remind ourselves what it looks like to work with Keras and TensorFlow. In the past, it would take hundreds of lines of code to define a simple network. In the Keras framework, a network can be instantiated in under three lines of code! For this recipe, we will introduce a few of the basic tools needed to understand the neural networks that we will work with in this chapter.

Getting ready

For this recipe, we need to ensure that we have all the appropriate tools to compile our code. You need the following pieces to make this recipe happen:

• A computer with an NVIDIA GPU
• Ubuntu 16.04
•  NVIDIA Docker installed...
