Deep Learning with R for Beginners

By: Mark Hodnett, Joshua F. Wiley, Yuxi (Hayden) Liu, Pablo Maldonado

Overview of this book

Deep learning has a range of practical applications in several domains, while R is the preferred language for designing and deploying deep learning models. This Learning Path introduces you to the basics of deep learning and even teaches you to build a neural network model from scratch. As you make your way through the chapters, you’ll explore deep learning libraries and understand how to create deep learning models for a variety of challenges, right from anomaly detection to recommendation systems. The Learning Path will then help you cover advanced topics, such as generative adversarial networks (GANs), transfer learning, and large-scale deep learning in the cloud, in addition to model optimization, overfitting, and data augmentation. Through real-world projects, you’ll also get up to speed with training convolutional neural networks (CNNs), recurrent neural networks (RNNs), and long short-term memory networks (LSTMs) in R. By the end of this Learning Path, you’ll be well-versed with deep learning and have the skills you need to implement a number of deep learning concepts in your research work or projects.

Chapter 7. Natural Language Processing Using Deep Learning

This chapter will demonstrate how to use deep learning for natural language processing (NLP). NLP is the processing of human language text. NLP is a broad term for a number of different tasks involving text data, which include (but are not limited to) the following:

  • Document classification: Classifying documents into different categories based on their subject
  • Named entity recognition: Extracting key information from documents, for example, people, organizations, and locations
  • Sentiment analysis: Classifying comments, tweets, or reviews as positive or negative sentiment
  • Language translation: Translating text data from one language to another
  • Part of speech tagging: Assigning the type to each word in a document, which is usually used in conjunction with another task

In this chapter, we will look at document classification, which is probably the most common NLP technique. This chapter follows a different structure to previous chapters, as...
