Overview of this book

Applying deep learning approaches to various NLP tasks can take your computational algorithms to a completely new level in terms of speed and accuracy. Deep Learning for Natural Language Processing starts by highlighting the basic building blocks of the natural language processing domain. The book goes on to introduce the problems that you can solve using state-of-the-art neural network models. After this, delving into the various neural network architectures and their specific areas of application will help you to understand how to select the best model to suit your needs. As you advance through this deep learning book, you’ll study convolutional, recurrent, and recursive neural networks, in addition to covering long short-term memory networks (LSTM). Understanding these networks will help you to implement their models using Keras. In later chapters, you will be able to develop a trigger word detection application using NLP techniques such as attention model and beam search. By the end of this book, you will not only have sound knowledge of natural language processing, but also be able to select the best text preprocessing and neural network models to solve a number of NLP issues.

Introduction

We encounter different kinds of data in our day-to-day lives, and some of this data has temporal dependencies (dependencies over time) while some does not. For example, an image by itself contains the information it wants to convey. However, data forms such as audio and video have dependencies over time. They cannot convey information if a fixed point in time is taken into consideration. Based on the problem statement, the input that's needed in order to solve the problem can differ. If we have a model to detect a particular person in a frame, a single image can be used as input. However, if we need to detect their actions, we need a stream of images, contiguous in time, as the input. We can understand the person's actions by analyzing these images together, but not independently.

While watching a movie, a particular scene makes sense because its context is known, and we remember all the information gathered before in the movie to understand the current scene. This...
