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.

Understanding Convolution Neural Networks

Now let's walk through the technical details of a CNN. First, we will discuss the convolution operation and introduce some terminology, such as filter size, stride, and padding. In brief, filter size refers to the window size of the convolution operation, stride refers to the distance between two movements of the convolution window, and padding refers to the way you handle boundaries of the input. We will also discuss an operation that is known as deconvolution or transposed convolution. Then we will discuss the details of the pooling operation. Finally, we will discuss how to connect fully connected layers and the two-dimensional outputs produced by the convolution and pooling layers and how to use the output for classification or regression.

Convolution operation

In this section, we will discuss the convolution operation in detail. First we will discuss the convolution operation without stride and padding, next we will describe the convolution operation...
