Overview of this book

Learning how to solve natural language processing (NLP) problems is an important skill to master due to the explosive growth of data combined with the demand for machine learning solutions in production. Natural Language Processing with TensorFlow, Second Edition, will teach you how to solve common real-world NLP problems with a variety of deep learning model architectures. The book starts by getting readers familiar with NLP and the basics of TensorFlow. Then, it gradually teaches you different facets of TensorFlow 2.x. In the following chapters, you then learn how to generate powerful word vectors, classify text, generate new text, and generate image captions, among other exciting use-cases of real-world NLP. TensorFlow has evolved to be an ecosystem that supports a machine learning workflow through ingesting and transforming data, building models, monitoring, and productionization. We will then read text directly from files and perform the required transformations through a TensorFlow data pipeline. We will also see how to use a versatile visualization tool known as TensorBoard to visualize our models. By the end of this NLP book, you will be comfortable with using TensorFlow to build deep learning models with many different architectures, and efficiently ingest data using TensorFlow Additionally, you’ll be able to confidently use TensorFlow throughout your machine learning workflow.

Word2vec – Learning Word Embeddings

In this chapter, we will discuss a topic of paramount importance in NLP—Word2vec, a data-driven technique for learning powerful numerical representations (that is, vectors) of words or tokens in a language. Languages are complex. This warrants sound language understanding capabilities in the models we build to solve NLP problems. When transforming words to a numerical representation, a lot of methods aren’t able to sufficiently capture the semantics and contextual information that word carries. For example, the feature representation of the word forest should be very different from oven as these words are rarely used in similar contexts, whereas the representations of forest and jungle should be very similar. Not being able to capture this information leads to underperforming models.

Word2vec tries to overcome this problem by learning word representations by consuming large amounts of text.

Word2vec is called...
