Implementing spam detection with Sparkling Water

In this recipe, we'll look at how to implement a spam detector by extracting data, transforming and tokenizing messages, building Spark's Tf-IDF model, and expanding messages to feature vectors. We'll also create and evaluate H2O's deep learning model. Lastly, we will use the models to detect spam messages.

Getting ready

To step through this recipe, you will need a running Spark Cluster in any one of the following modes: Local, standalone, YARN, Mesos. Include the Spark MLlib package in the build.sbt file so that it downloads the related libraries and the API can be used. Install Hadoop (optionally), Scala, and Java. Also, install Sparkling Water as discussed in the preceding recipe.
