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 3. Deep Learning Fundamentals

In the previous chapter, we created some machine learning models using neural network packages in R. This chapter will look at some of the fundamentals of neural networks and deep learning by creating a neural network using basic mathematical and matrix operations. This application sample will be useful for explaining some key parameters in deep learning algorithms and some of the optimizations that allow them to train on large datasets. We will also demonstrate how to evaluate different hyper-parameters for models to find the best set. In the previous chapter, we briefly looked at the problem of overfitting; this chapter goes into that topic in more depth and looks at how you can overcome this problem. It includes an example use case using dropout, the most common regularization technique in deep learning.

This chapter covers the following topics:

  • Building neural networks from scratch in R
  • Common parameters in deep learning
  • Some key components in deep learning...
