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.

Previous Versions of Neural Networks

Around 40 years ago, it became clear that Feed Forward Neural Networks (FFNNs) could not capture time-variable dependencies, which are essential for capturing the time-variable properties of a signal. Modeling time-variable dependencies is very important in many applications involving real-world data, such as speech and video, in which data has time-variable properties. Also, human biological neural networks have a recurrent relationship, so it is the most obvious direction to take. How could this recurrent relationship be added to existing feedforward networks?

One of the first attempts to achieve this was done by adding delay elements, and the network was called the Time-Delay Neural Network, or TDNN for short.

In this network, as the following figure shows, the delay elements are added to the network and the past inputs are given to the network along with the current timestep as the input to the network. This definitely has an advantage over the traditional...
