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.

Getting to know the data


Let's first understand the data we are working with both directly and indirectly. There are two datasets we will rely on:

We will not engage the first dataset directly, but it is essential for caption learning. This dataset contains images and their respective class labels (for example, cat, dog, and car). We will use a CNN that is already trained on this dataset, so we do not have to download and train on this dataset from scratch. Next we will use the MS-COCO dataset, which contains images and their respective captions. We will directly learn from this dataset by mapping the image to a fixed-size feature vector, using the CNN, and then map this vector to the corresponding caption using an LSTM (we will discuss the process in detail later).

ILSVRC ImageNet dataset

ImageNet is an image dataset that contains a large set of images (~1 million) and their respective...
