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.

AutoKeras

AutoKeras [6] provides functions to automatically search for architecture and hyperparameters of deep learning models. The framework uses Bayesian optimization for efficient neural architecture search. You can install the alpha version by using pip:

pip3 install autokeras # for 1.19 version

The architecture is explained in Figure 13.3 [6]:

The architecture follows these steps:

  1. The user calls the API.
  2. The searcher generates neural architectures on the CPU.
  3. Real neural networks with parameters are built on RAM from the neural architectures.
  4. The neural network is copied to the GPU for training.
  5. The trained neural networks are saved on storage devices.
  6. The searcher is updated based on the training results.

Steps 2 to 6 will repeat until a time limit is reached.
