Natural Language Processing with TensorFlow

By: Motaz Saad, Thushan Ganegedara

Overview of this book

Natural language processing (NLP) supplies the majority of data available to deep learning applications, while TensorFlow is the most important deep learning framework currently available. Natural Language Processing with TensorFlow brings TensorFlow and NLP together to give you invaluable tools to work with the immense volume of unstructured data in today’s data streams, and apply these tools to specific NLP tasks. Thushan Ganegedara starts by giving you a grounding in NLP and TensorFlow basics. You'll then learn how to use Word2vec, including advanced extensions, to create word embeddings that turn sequences of words into vectors accessible to deep learning algorithms. Chapters on classical deep learning algorithms, like convolutional neural networks (CNN) and recurrent neural networks (RNN), demonstrate important NLP tasks as sentence classification and language generation. You will learn how to apply high-performance RNN models, like long short-term memory (LSTM) cells, to NLP tasks. You will also explore neural machine translation and implement a neural machine translator. After reading this book, you will gain an understanding of NLP and you'll have the skills to apply TensorFlow in deep learning NLP applications, and how to perform specific NLP tasks.

Appendix A. Mathematical Foundations and Advanced TensorFlow

Here we will discuss some of the concepts that will be useful to understand details provided in the chapters. First we will discuss several mathematical data structures found throughout the book, followed by a description about various operations performed on those data structures. Next, we will discuss the concept of probabilities. Probabilities play a vital role in machine learning, as they usually give insights to how uncertain a model is about its prediction. Thereafter, we discuss a high-level library known as Keras in TensorFlow, as well as how to implement a neural machine translator with the seq2seq sublibrary in TensorFlow. Finally we conclude this section with a guide on how to use the TensorBoard as a visualization tool for word embeddings.
