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.

Implementing our first neural network

Great! Now that you've learned the architecture, basics, and scoping mechanism of TensorFlow, it's high time that we move on and implement something moderately complex. Let's implement a neural network. Precisely, we will implement a fully connected neural network model that we discussed in Chapter 1, Introduction to Natural Language Processing.

One of the stepping stones to the introduction of neural networks is to implement a neural network that is able to classify digits. For this task, we will be using the famous MNIST dataset made available at http://yann.lecun.com/exdb/mnist/. You might feel a bit skeptical regarding our using a computer vision task rather than a NLP task. However, vision tasks can be implemented with less preprocessing and are easy to understand.

As this is our first encounter with neural networks, we will walk through the main parts of the example. However, note that I will only walk through the crucial bits of...
