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


After we passed our model-evaluation stage and decided to select the estimated and evaluated model as our final models, our next task is to interpret the results to the telco company and their clients.

In terms of explaining the machine learning results, the telco company is particularly interested in understanding what influences the Call Center call volume as well as what impacts the subscriber churn. Of course, they are also open to other special insights.

We will work on these tasks, with our focus on big influencing features and some special insights.

Descriptive statistics and visualizations

With R or SPSS on Spark, as well as MLlib in place, one advantage is to obtain analytical results fast. So, quickly, we have obtained the following insights as summarized by the following tables.

For subscriber churn, we have the following two tables that summarize the subscriber churn ratios, per their phone manufactures and per our market segments of six main categories. Producing...
