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.

Summary

We covered a lot of ground in this chapter. We looked at activation functions and built our first true deep learning models using MXNet. Then we took a real-life dataset and created two use cases for applying a machine learning model. The first use case was to predict which customers will return in the future based on their past activity. This was a binary classification task. The second use case was to predict how much a customer will spend in the future based on their past activity. This was a regression task. We ran both models first on a small dataset and used different machine learning libraries to compare them against our deep learning model. Our deep learning model out-performed all of the algorithms.

We then took this further by using a dataset that was 100 times bigger. We built a larger deep learning model and adjusted our parameters to get an increase in our...
