Hands-On Data Analysis with Scala

By: Rajesh Gupta

Overview of this book

Efficient business decisions with an accurate sense of business data helps in delivering better performance across products and services. This book helps you to leverage the popular Scala libraries and tools for performing core data analysis tasks with ease. The book begins with a quick overview of the building blocks of a standard data analysis process. You will learn to perform basic tasks like Extraction, Staging, Validation, Cleaning, and Shaping of datasets. You will later deep dive into the data exploration and visualization areas of the data analysis life cycle. You will make use of popular Scala libraries like Saddle, Breeze, Vegas, and PredictionIO for processing your datasets. You will learn statistical methods for deriving meaningful insights from data. You will also learn to create applications for Apache Spark 2.x on complex data analysis, in real-time. You will discover traditional machine learning techniques for doing data analysis. Furthermore, you will also be introduced to neural networks and deep learning from a data analysis standpoint. By the end of this book, you will be capable of handling large sets of structured and unstructured data, perform exploratory analysis, and building efficient Scala applications for discovering and delivering insights

Overview of object-oriented and functional programming

Scala supports object-oriented and functional styles of programming. Both of these programming paradigms have been proven to help model and solve real-world problems. In this section, we will explore both of these styles of programming using Scala.

Object-oriented programming using Scala

In the object-oriented paradigm, you think in terms of objects and classes. A class can be thought of as a template that acts as a basis for creating objects of that type. For example, a Vehicle class can represent real-world automobiles with the following attributes:

  • vin (a unique vehicle identification number)
  • manufacturer
  • model
  • modelYear
  • finalAssemblyCountry

A concrete instance of...
