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.

Application Areas of CNNs

Now that we understand the architecture of CNNs, let's look at some applications. In general, CNNs are great for data that has a spatial structure. Examples of types of data that has a spatial structure are sound, images, video, and text.

In natural language processing, CNNs are used for various tasks such as sentence classification. One example is the task of sentiment classification, where a sentence is classified as belonging to a predetermined group of classes.

As discussed earlier, CNNs are applied at the character level to classification tasks such as sentiment classification, especially on noisy datasets such as social media posts.

CNNs are more commonly applied in computer vision. Here are some applications in this area:

  • Facial recognition

    Most social networking sites employ CNNs to detect faces and subsequently perform tasks such as tagging.
