R Deep Learning Essentials. - Second Edition

By: Mark Hodnett, Joshua F. Wiley

Overview of this book

Deep learning is a powerful subset of machine learning that is very successful in domains such as computer vision and natural language processing (NLP). This second edition of R Deep Learning Essentials will open the gates for you to enter the world of neural networks by building powerful deep learning models using the R ecosystem. This book will introduce you to the basic principles of deep learning and teach you to build a neural network model from scratch. As you make your way through the book, you will explore deep learning libraries, such as Keras, MXNet, and TensorFlow, and create interesting deep learning models for a variety of tasks and problems, including structured data, computer vision, text data, anomaly detection, and recommendation systems. You’ll cover advanced topics, such as generative adversarial networks (GANs), transfer learning, and large-scale deep learning in the cloud. In the concluding chapters, you will learn about the theoretical concepts of deep learning projects, such as model optimization, overfitting, and data augmentation, together with other advanced topics. By the end of this book, you will be fully prepared and able to implement deep learning concepts in your research work or projects.

Setting up a local computer for deep learning

At the time of writing this book, it is possible to purchase a computer with a GPU card suitable for deep learning for under $1,000. The current on-demand cost of the cheapest GPU computer on AWS is $0.90 per hour, which is equivalent to using the machine constantly for 46 days. So, if you are just starting with deep learning, cloud resources are the cheapest way to begin. Once you have learned the basics, then you may decide to get a GPU-based computer, but even then you may continue using cloud resources for deep learning. You have much more flexibility in the cloud. For example, in AWS, you can get a p3.16xlarge machine with 8 Tesla V100 GPU cards for an on-demand price of $24.48 per hour. An equivalent box is the DGX-1 from NVIDIA (https://www.nvidia.com/en-us/data-center/dgx-1/), which has 8 Tesla V100 GPU cards and costs $149...
