Apache Spark Machine Learning Blueprints

By: Alex Liu

Overview of this book

There's a reason why Apache Spark has become one of the most popular tools in Machine Learning – its ability to handle huge datasets at an impressive speed means you can be much more responsive to the data at your disposal. This book shows you Spark at its very best, demonstrating how to connect it with R and unlock maximum value not only from the tool but also from your data. Packed with a range of project "blueprints" that demonstrate some of the most interesting challenges that Spark can help you tackle, you'll find out how to use Spark notebooks and access, clean, and join different datasets before putting your knowledge into practice with some real-world projects, in which you will see how Spark Machine Learning can help you with everything from fraud detection to analyzing customer attrition. You'll also find out how to build a recommendation engine using Spark's parallel computing powers.

Results explanation


Once we pass our model evaluation and decide to select the estimated model as our final model, we need to interpret the results to the company executives and also their technicians.

In the following, we discuss some commonly used ways of interpreting our results, one using tables and another using graphs, with our focus on impact assessment.

Some users may prefer to interpret our results in terms of ROIs, for which the cost and benefit data is needed. Once we have the cost and benefit data, our results here can be easily expanded to cover the ROI issues. Also, some optimization may need to be applied for real decision making.

Impact assessments

As discussed in section, Spark for a holistic view, the main purpose of this project is to gain a holistic view of sales team success. For example, the company wishes to understand the impact of marketing on sales success in comparison to training and other factors.

As we have our linear regression model estimated, one easy way of comparing...
