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.

Summary


This chapter presented a brief introduction to neural networks and deep neural networks. Using multiple hidden layers, deep neural networks have been a revolution in machine learning. They consistently outperform other machine learning tasks, especially in areas such as computer vision, natural-language processing, and speech-recognition.

The chapter also looked at some of the theory behind neural networks, the difference between shallow neural networks and deep neural networks, and some of the misconceptions that currently exist concerning deep learning.

We closed this chapter with a discussion on how to set up R and the importance of using a GUI (RStudio). This section discussed the deep learning libraries available in R (MXNet, Keras, and TensorFlow), GPUs, and reproducibility.

In the next chapter, we will begin to train neural networks and generate our own predictions.
