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.

Automatic model generation

Model generation and hyperparameter tuning is the typical third macro-step of a machine learning pipeline (see Figure 13.1).

Model generation consists of creating a suitable model for solving specific tasks. For instance, you will probably use CNNs for visual recognition, and you will use RNNs for either time series analysis or for sequences. Of course, many variants are possible, each of which is manually crafted through a process of trial and error and works for very specific domains.

Hyperparameter tuning happens once the model is manually crafted. This process is generally very computationally expensive and can significantly change the quality of the results in a positive way. That’s because tuning the hyperparameters can help to optimize our model further.

Automatic model generation is the ultimate goal of any AutoML pipeline. How can this be achieved? One approach consists of generating the model by combining a set of primitive operations...
