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.

Special types of matrices

Identity matrix

An identity matrix is where it is equal to 1 on the diagonal of the matrix and 0 everywhere else. Mathematically, it can be shown as follows:

Identity matrix

This would look like the following:

Identity matrix

Here, Identity matrix.

The identity matrix gives the following nice property when multiplied with another matrix A:

Identity matrix

Diagonal matrix

A diagonal matrix is a more general case of the identity matrix, where the values along the diagonal can take any value and the off-diagonal values are zeros:

Diagonal matrix

Tensors

An n-dimensional matrix is called a tensor. In other words, a matrix with an arbitrary number of dimensions is called a tensor. For example, a four-dimensional tensor can be denoted as shown here:

Tensors

Here, R is the real number space.
