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.

What is deep learning and why do we need it?


Deep learning is an emerging subfield of machine learning. It employs artificial neural network (ANN) algorithms to process data, derive patterns or to develop abstractions, simulating the thinking process of a biological brain. And those ANNs usually contain more than one hidden layer, which is how deep learning got its name—machine learning with stacked neural networks. Going beyond shallow ANNs (usually with only one hidden layer), a deep learning model with the right architectures and parameters can better represent complex non-linear relationships.

Here is an example of a shallow ANN:

And an example of a deep learning model:

Don't feel scared, regardless of how complicated it might sound or look. We will be going from shallow to deep dives into deep learning throughout five projects in this book.

First of all, as a part of the broad family of machine learning, deep learning can be used in supervised learning, semi-supervised learning, as well...
