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.

Many-to-one and many-to-many RNN examples

In this recipe, we summarize what has been discussed with RNNs by providing various examples of RNN mapping. For the sake of simplicity, we will adopt Keras and will show how to write one-to-one, one-to-many, many-to-one, and many-to-many mappings as represented in the following figure:

How to do it...

We proceed with the recipe as follows:

  1. If you want to create a one-to-one mapping, this is not an RNN but instead a dense layer. Suppose to have a model already defined and you want to add a Dense network. Then this is easily implemented in Keras:
model = Sequential()
model.add(Dense(output_size...
