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.

Model estimation

For this project, our strategy for model estimation is to employ a complete SPSS Modeler stream developed from previous sections and then use SPSS Analytics Server for Spark Implementation. Our stream consists of SPSS Modeler Nodes for data treatment, as described in section, Data treatment and also model training Nodes with MLlib codes described in section, Methods for recommendation development as we prepared our SPSS Modeler to be ready to use MLlib in section, Spark for a recommendation engine.

As noted before, our IBM SPSS Modeler nodes created from Custom Dialog Builder depend on the Spark environment and will only run against IBM SPSS Analytic Server. SPSS Analytics Server is a tool to manage all the computing for model estimations and we have to employ IBM SPSS Analytic Server to implement the model estimation for this project, which makes everything easy for us. However, we also need to arrange for SPSS on the Spark system to run models for each movie category and...
