Overview of this book

Deep Learning with TensorFlow and Keras teaches you neural networks and deep learning techniques using TensorFlow (TF) and Keras. You'll learn how to write deep learning applications in the most powerful, popular, and scalable machine learning stack available. TensorFlow 2.x focuses on simplicity and ease of use, with updates like eager execution, intuitive higher-level APIs based on Keras, and flexible model building on any platform. This book uses the latest TF 2.0 features and libraries to present an overview of supervised and unsupervised machine learning models and provides a comprehensive analysis of deep learning and reinforcement learning models using practical examples for the cloud, mobile, and large production environments. This book also shows you how to create neural networks with TensorFlow, runs through popular algorithms (regression, convolutional neural networks (CNNs), transformers, generative adversarial networks (GANs), recurrent neural networks (RNNs), natural language processing (NLP), and graph neural networks (GNNs)), covers working example apps, and then dives into TF in production, TF mobile, and TensorFlow with AutoML.

Cool applications of GANs

We have seen that the generator can learn how to forge data. This means that it learns how to create new synthetic data that is created by the network that appears to be authentic and human-made. Before going into the details of some GAN code, we would like to share the results of the paper [6] (code is available online at https://github.com/hanzhanggit/StackGAN) where a GAN has been used to synthesize forged images starting from a text description. The results are impressive: the first column is the real image in the test set and all the rest of the columns are the images generated from the same text description by Stage-I and Stage-II of StackGAN. More examples are available on YouTube (https://www.youtube.com/watch?v=SuRyL5vhCIM&feature=youtu.be):

A picture containing text, bird, outdoor, standing  Description automatically generated

Figure 9.15: Image generation of birds, using GANs

A group of flowers  Description automatically generated with low confidence

Now let us see how a GAN can learn to “forge” the MNIST dataset...
