Deep Learning with Keras

By: Antonio Gulli, Sujit Pal

Overview of this book

This book starts by introducing you to supervised learning algorithms such as simple linear regression, the classical multilayer perceptron and more sophisticated deep convolutional networks. You will also explore image processing with recognition of handwritten digit images, classification of images into different categories, and advanced objects recognition with related image annotations. An example of identification of salient points for face detection is also provided. Next you will be introduced to Recurrent Networks, which are optimized for processing sequence data such as text, audio or time series. Following that, you will learn about unsupervised learning algorithms such as Autoencoders and the very popular Generative Adversarial Networks (GANs). You will also explore non-traditional uses of neural networks as Style Transfer. Finally, you will look at reinforcement learning and its application to AI game playing, another popular direction of research and application of neural networks.

Preface

Installing Keras on Amazon AWS


Installing TensorFlow and Keras on Amazon is very simple. Indeed, it is possible to use a prebuilt AMI named TFAMI.v3 that is open and free (for more information, refer to https://github.com/ritchieng/tensorflow-aws-ami), shown as follows:

This AMI runs TensorFlow in less than five minutes and supports TensorFlow, Keras, OpenAI Gym, and all dependencies. As of January 2017, it supports the following:

  • TensorFlow 0.12
  • Keras 1.1.0
  • TensorLayer 1.2.7
  • CUDA 8.0
  • CuDNN 5.1
  • Python 2.7
  • Ubuntu 16.04

In addition, TFAMI.v3 works on P2 computing instances (for more information, refer to https://aws.amazon.com/ec2/instance-types/#p2), as shown in the following screenshot:

Some features of P2 instances are as follows:
