When collecting real-world data between individual measures or events, there are usually very intricate and highly complex relationships to observe. The guiding example for this chapter is the observation of click events that users generate on a website and its subdomains. Such data is both interesting and challenging to investigate. It is interesting, as there are usually many patterns that groups of users show in their browsing behavior and certain rules they might follow. Gaining insights about user groups, in general, is of interest, at least for the company running the website and might be the focus of their data science team. Methodology aside, putting a production system in place that can detect patterns in real time, for instance, to find malicious behavior, can be very challenging technically. It is immensely valuable to be able...

Overview of this book
The purpose of machine learning is to build systems that learn from data. Being able to understand trends and patterns in complex data is critical to success; it is one of the key strategies to unlock growth in the challenging contemporary marketplace today. With the meteoric rise of machine learning, developers are now keen on finding out how can they make their Spark applications smarter.
This book gives you access to transform data into actionable knowledge. The book commences by defining machine learning primitives by the MLlib and H2O libraries. You will learn how to use Binary classification to detect the Higgs Boson particle in the huge amount of data produced by CERN particle collider and classify daily health activities using ensemble Methods for Multi-Class Classification.
Next, you will solve a typical regression problem involving flight delay predictions and write sophisticated Spark pipelines. You will analyze Twitter data with help of the doc2vec algorithm and K-means clustering. Finally, you will build different pattern mining models using MLlib, perform complex manipulation of DataFrames using Spark and Spark SQL, and deploy your app in a Spark streaming environment.
