TensorFlow 1.x Deep Learning Cookbook

Overview of this book

Deep neural networks (DNNs) have achieved a lot of success in the field of computer vision, speech recognition, and natural language processing. This exciting recipe-based guide will take you from the realm of DNN theory to implementing them practically to solve real-life problems in the artificial intelligence domain. In this book, you will learn how to efficiently use TensorFlow, Google’s open source framework for deep learning. You will implement different deep learning networks, such as Convolutional Neural Networks (CNNs), Recurrent Neural Networks (RNNs), Deep Q-learning Networks (DQNs), and Generative Adversarial Networks (GANs), with easy-to-follow standalone recipes. You will learn how to use TensorFlow with Keras as the backend. You will learn how different DNNs perform on some popularly used datasets, such as MNIST, CIFAR-10, and Youtube8m. You will not only learn about the different mobile and embedded platforms supported by TensorFlow, but also how to set up cloud platforms for deep learning applications. You will also get a sneak peek at TPU architecture and how it will affect the future of DNNs. By using crisp, no-nonsense recipes, you will become an expert in implementing deep learning techniques in growing real-world applications and research areas such as reinforcement learning, GANs, and autoencoders.

Higher-level APIs-Keras

Keras is a higher-level API used with TensorFlow as the backend. Adding layers to it is as easy as adding a single line of code. After the model architecture, using one line of code, you can compile and fit the model. Later, it can be used for prediction. Declaration of variables, placeholders, and even the session is managed by the API.

How to do it...

We proceed with Keras as follows:

  1. As the first step, we define the type of our model. Keras offers two types of models: sequential and Model class API. Keras offers various types of neural network layers:
# Import the model and layers needed  
from keras.model import Sequential 
from keras.layers import Dense 
 
model = Sequential() 
  1. Add the layers...
