Mastering Predictive Analytics with R - Second Edition

By: James D. Miller, Rui Miguel Forte

Overview of this book

R offers a free and open source environment that is perfect for both learning and deploying predictive modeling solutions. With its constantly growing community and plethora of packages, R offers the functionality to deal with a truly vast array of problems. The book begins with a dedicated chapter on the language of models and the predictive modeling process. You will understand the learning curve and the process of tidying data. Each subsequent chapter tackles a particular type of model, such as neural networks, and focuses on the three important questions of how the model works, how to use R to train it, and how to measure and assess its performance using real-world datasets. How do you train models that can handle really large datasets? This book will also show you just that. Finally, you will tackle the really important topic of deep learning by implementing applications on word embedding and recurrent neural networks. By the end of this book, you will have explored and tested the most popular modeling techniques in use on real- world datasets and mastered a diverse range of techniques in predictive analytics using R.

Chapter 14. Deep Learning

The purpose of this chapter is to tackle the very important topic of deep learning and the how and why of how it has been growing in importance to the statistical field in recent years.

We will start by providing a bit of an explanation of what machine learning is then move on with some discussion around what deep learning is, how it compares to machine learning, and the reasoning behind how it has been continually growing in importance almost day by day. For clarification of the concepts, we will then present two hallmark sample use cases: word embedding with some talk about natural language processing or NLP application logic, and recurrent neural networks (RNNs) which is an interesting and more advanced and efficient type of artificial neural network.
