Overview of this book

Machine learning aims to extract knowledge from data, relying on fundamental concepts in computer science, statistics, probability, and optimization. Learning about algorithms enables a wide range of applications, from everyday tasks such as product recommendations and spam filtering to cutting edge applications such as self-driving cars and personalized medicine. You will gain hands-on experience of applying these principles using Apache Spark, a resilient cluster computing system well suited for large-scale machine learning tasks. This book begins with a quick overview of setting up the necessary IDEs to facilitate the execution of code examples that will be covered in various chapters. It also highlights some key issues developers face while working with machine learning algorithms on the Spark platform. We progress by uncovering the various Spark APIs and the implementation of ML algorithms with developing classification systems, recommendation engines, text analytics, clustering, and learning systems. Toward the final chapters, we’ll focus on building high-end applications and explain various unsupervised methodologies and challenges to tackle when implementing with big data ML systems.

Operating on DataFrames programmatically without SQL


In this recipe, we explore how to manipulate with code and method calls only (without SQL). The DataFrames have their own methods that allow you to perform SQL-like operations using a programmatic approach. We demonstrate some of these commands such as select(), show(), and explain() to get the point across that the DataFrame itself is capable of wrangling and manipulating the data without using SQL.

How to do it...

  1. Start a new project in IntelliJ or in an IDE of your choice. Make sure the necessary JAR files are included.
  1. Set up the package location where the program will reside
package spark.ml.cookbook.chapter3 
  1. Set up the imports related to DataFrames and the required data structures and create the RDDs as needed for the example
import org.apache.spark.sql._
  1. Import the packages for setting up logging level for log4j. This step is optional, but we highly recommend it (change the level appropriately as you move through the development cycle...
