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.

Dynamic embeddings

So far, all the embeddings we have considered have been static; that is, they are deployed as a dictionary of words (and subwords) mapped to fixed dimensional vectors. The vector corresponding to a word in these embeddings is going to be the same regardless of whether it is being used as a noun or verb in the sentence, for example, the word “ensure” (the name of a health supplement when used as a noun, and to make certain when used as a verb). It also provides the same vector for polysemous words or words with multiple meanings, such as “bank” (which can mean different things depending on whether it co-occurs with the word “money” or “river”). In both cases, the meaning of the word changes depending on clues available in its context, the sentence. Dynamic embeddings attempt to use these signals to provide different vectors for words based on their context.

Dynamic embeddings are deployed as trained networks...
