Java Data Analysis

By: John R. Hubbard

Overview of this book

Data analysis is a process of inspecting, cleansing, transforming, and modeling data with the aim of discovering useful information. Java is one of the most popular languages to perform your data analysis tasks. This book will help you learn the tools and techniques in Java to conduct data analysis without any hassle. After getting a quick overview of what data science is and the steps involved in the process, you’ll learn the statistical data analysis techniques and implement them using the popular Java APIs and libraries. Through practical examples, you will also learn the machine learning concepts such as classification and regression. In the process, you’ll familiarize yourself with tools such as Rapidminer and WEKA and see how these Java-based tools can be used effectively for analysis. You will also learn how to analyze text and other types of multimedia. Learn to work with relational, NoSQL, and time-series data. This book will also show you how you can utilize different Java-based libraries to create insightful and easy to understand plots and graphs. By the end of this book, you will have a solid understanding of the various data analysis techniques, and how to implement them using Java.

Chapter 11. Big Data Analysis with Java

"In pioneer days they used oxen for heavy pulling, and when one ox couldn't budge a log, they didn't try to grow a larger ox. We shouldn't be trying for bigger computers, but for more systems of computers."

– Grace Hopper (1906-1992)

The term big data generally refers to algorithms for the storage, retrieval, and analysis of massive datasets that are too large to be managed by a single file server. Commercially, these algorithms were pioneered by Google. Two of their early benchmark algorithms, PageRank and MapReduce, are among those considered in this chapter.

Note

The word "googol" was coined by the nine-year-old nephew of the American mathematician Edward Kasner in the 1930s. The word was meant to stand for 10100. At that time, it had been estimated that the number of particles in the universe was about 1080. Kasner later coined the additional word "googolplex" to stand...
