Java: Data Science Made Easy

By: Richard M. Reese, Jennifer L. Reese, Alexey Grigorev

Overview of this book

Data science is concerned with extracting knowledge and insights from a wide variety of data sources to analyse patterns or predict future behaviour. It draws from a wide array of disciplines including statistics, computer science, mathematics, machine learning, and data mining. In this course, we cover the basic as well as advanced data science concepts and how they are implemented using the popular Java tools and libraries.The course starts with an introduction of data science, followed by the basic data science tasks of data collection, data cleaning, data analysis, and data visualization. This is followed by a discussion of statistical techniques and more advanced topics including machine learning, neural networks, and deep learning. You will examine the major categories of data analysis including text, visual, and audio data, followed by a discussion of resources that support parallel implementation. Throughout this course, the chapters will illustrate a challenging data science problem, and then go on to present a comprehensive, Java-based solution to tackle that problem. You will cover a wide range of topics – from classification and regression, to dimensionality reduction and clustering, deep learning and working with Big Data. Finally, you will see the different ways to deploy the model and evaluate it in production settings. By the end of this course, you will be up and running with various facets of data science using Java, in no time at all. This course contains premium content from two of our recently published popular titles: - Java for Data Science - Mastering Java for Data Science

Extensions to the standard library


The standard Java library is quite powerful, but some things take a long time to write using it or they are simply missing. There are a number of extensions to the standard library, and the most prominent libraries are Apache Commons (a collection of libraries) and Google Guava. They make it easier to use the standard API or extend it, for example, by adding new collections or implementations.

To begin with, we will briefly go over the most relevant parts of these libraries, and later on we will see how they are used in practice.

Apache Commons

Apache Commons is a collection of open source libraries for Java, with the goal of creating reusable Java components. There are quite a few of them, including Apache Commons Lang, Apache Commons IO, Apache Commons Collections, and many others.

Commons Lang

Apache Commons Lang is a set of utility classes that extend the java.util package and they make the life of a Java developer a lot easier by providing many little...
