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.

Introducing Convolution Neural Networks


In this section, you will learn about CNNs. Specifically, you will first get an understanding of the sort of operations present in a CNN, such as convolution layers, pooling layers, and fully connected layers. Next, we will briefly see how all of these are connected to form an end-to-end model. Then we will dive into the details of each of these operations, define them mathematically, and learn how the various hyperparameters involved with these operations change the output produced by them.

CNN fundamentals

Now, let's explore the fundamental idea behind a CNN without delving into too much technical detail. As noted in the preceding paragraph, a CNN is a stack of layers, such as convolution layers, pooling layers, and fully connected layers. We will discuss each of these to understand their role in the CNN.

Initially, the input is connected to a set of convolution layers. These convolution layers slide a patch of weights (sometimes called the convolution...
