Deep Learning for Natural Language Processing

By: Karthiek Reddy Bokka, Shubhangi Hora, Tanuj Jain, Monicah Wambugu

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.

Designing a Neural Network and Its Applications

Common machine learning techniques are used when training and designing a neural network. Neural networks can be classified as:

  • Supervised neural networks
  • Unsupervised neural networks

Supervised neural networks

These are like the example used in the previous section (predicting the price of the house based on how many rooms it has). Supervised neural networks are trained on datasets consisting of sample inputs with their corresponding outputs. These are suitable for noise classification and making predictions.

There are two types of supervised learning methods:

  • Classification

    This is for problems that have discrete categories or classes as target outputs, for example the Iris dataset. The neural network learns from sample inputs and outputs how to correctly classify new data.

  • Regression

    This is for problems that have a range of continuous numerical values as target outputs, like the price of a house example. The neural network...
