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.

Summary


In this chapter, we discussed the topics of machine and deep learning and the difference between the two. We also mentioned how deep learning has the capacity to drive change in the world.

We saw how deep learning reduces the effort required by humans and listed some of the current applications where these algorithms have been successfully applied. We then looked at using word embedding for a use case such as NLP applications, and explained how it works.

Finally, we wrapped up with a discussion on neural networks, specifically RNNs.

With this chapter, we bring our journey to its end, having provided in-depth information around performance metrics and learning curves, polynomial regression, Poisson, and negative binomial regression, back-propagation, radial basis function networks, and others. We also discussed the process of working with very large datasets.

Hopefully you have enjoyed exploring and testing these popular modeling techniques and mastered a range of predictive analytics...
