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.

Summary


In this chapter, we discussed CNNs and their various applications. First, we went through a detailed explanation about what CNNs are and their ability to excel at machine learning tasks. Next we decomposed the CNN into several components, such as convolution and pooling layers, and discussed in detail how these operators work. Furthermore, we discussed several hyperparameters that are related to these operators such as filter size, stride, and padding. Then, to illustrate the functionality of CNNs, we walked through a simple example of classifying images of handwritten digits to the corresponding image. We also did a bit of analysis to see why the CNN fails to recognize some images correctly. Finally, we started talking about how CNNs are applied for NLP tasks. Concretely, we discussed an altered architecture of CNNs that can be used to classify sentences. We then implemented this particular CNN architecture and tested it on an actual sentence classification task.
