Overview of this book

Deep Learning with TensorFlow 2 and Keras, Second Edition teaches neural networks and deep learning techniques alongside 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 is the machine learning library of choice for professional applications, while Keras offers a simple and powerful Python API for accessing TensorFlow. TensorFlow 2 provides full Keras integration, making advanced machine learning easier and more convenient than ever before. This book also introduces neural networks with TensorFlow, runs through the main applications (regression, ConvNets (CNNs), GANs, RNNs, NLP), covers two working example apps, and then dives into TF in production, TF mobile, and using 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 its context.

Dynamic embeddings are deployed as trained networks that convert your...
