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 5. Image Classification Using Convolutional Neural Networks

It is not an exaggeration to say that the huge growth of interest in deep learning can be mostly attributed to convolutional neural networks. Convolutional neural networks (CNNs) are the main building blocks of image classification models in deep learning, and have replaced most techniques that were previously used by specialists in the field. Deep learning models are now the de facto method to perform all large-scale image tasks, including image classification, object detection, detecting artificially generated images, and even attributing text descriptions to images. In this chapter, we will look at some of these techniques.

Why are CNNs so important? To explain why, we can look at the history of the ImageNet competition. The ImageNet competition is an open large-scale image classification challenge that has one thousand categories. It can be considered as the unofficial world championship for image classification.
