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.

Summary


In this chapter, we switched our focus to SPSS on Spark with which we processed data on Spark and then built a model for movie recommendations; using this, we produced movie recommendations for individual users.

Specifically, we first selected collaborative filtering as our method as per business needs after we prepared Spark computing with SPSS and loaded in preprocessed data. Second, we worked on data preparation with SPSS Modeler. Third, we implemented model estimation using SPSS Analytic Server. Fourth, we evaluated these estimated models by assessing error ratios. And finally, we deployed our machine learning results with some examples of recommending movies for individual users.

After this chapter, you will have gained a full understanding of how Apache Spark can be utilized to make your work easier and faster in conducting supervised machine learning and also gained a deeper understanding of developing recommendation engines. At the same time, you will have learned how SPSS...
