Use case - analyzing the MovieLens dataset

In the previous recipes, we saw various steps of performing data analysis. In this recipe, let's download the commonly used dataset for movie recommendations. The dataset is known as the MovieLens dataset. The dataset is quite applicable for recommender systems as well as potentially for other machine learning tasks.

Getting ready

To step through this recipe, you will need a running Spark cluster in any one of the modes, that is, local, standalone, YARN, or Mesos. For installing Spark on a standalone cluster, please refer to http://spark.apache.org/docs/latest/spark-standalone.html. Also, 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.

How to do it…

Let's see how to analyse the MovieLens dataset.

  1. Let's download the MovieLens dataset from the following location: https://drive.google.com/file/d/0Bxr27gVaXO5sRUZnMjBQR0lqNDA/view?usp=sharing...

Ever wonder why speech recognition systems don't understand the Scottish accent, or what would happen if an astronaut only ate mac 'n' cheese, or other spurious reflections you'd have at a bar? We did, then collated those deliberations into absurd research articles with fake figures and methodologies inspired by even more fictionally absurd studies.
