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


In this chapter, you have seen some advanced deep learning techniques. First, we looked at some image classification models and looked at some historical models. Next, we loaded an existing model with pre-trained weights into R and used it to classify a new image. We looked at transfer learning, which allows us to reuse an existing model as a base on which to build a deep learning model for new data. We built an image classifier model that could train on image files. This model also showed us how to use data augmentation and callbacks, which are used in many deep learning models. Finally, we demonstrated how we can build a model in R and create a REST endpoint for a prediction API that can be used from other applications or across the web.

R is a great language for data science and I believe it is easier to use and allows you to develop machine learning prototypes faster than the main alternative, Python. Now that it has support for some excellent deep learning frameworks in MXNet...
