Machine Learning with Apache Spark Quick Start Guide

Overview of this book

Every person and every organization in the world manages data, whether they realize it or not. Data is used to describe the world around us and can be used for almost any purpose, from analyzing consumer habits to fighting disease and serious organized crime. Ultimately, we manage data in order to derive value from it, and many organizations around the world have traditionally invested in technology to help process their data faster and more efficiently. But we now live in an interconnected world driven by mass data creation and consumption where data is no longer rows and columns restricted to a spreadsheet, but an organic and evolving asset in its own right. With this realization comes major challenges for organizations: how do we manage the sheer size of data being created every second (think not only spreadsheets and databases, but also social media posts, images, videos, music, blogs and so on)? And once we can manage all of this data, how do we derive real value from it? The focus of Machine Learning with Apache Spark is to help us answer these questions in a hands-on manner. We introduce the latest scalable technologies to help us manage and process big data. We then introduce advanced analytical algorithms applied to real-world use cases in order to uncover patterns, derive actionable insights, and learn from this big data.

Machine learning

Machine learning is an applied field of study within the broader subject of artificial intelligence that focuses on learning from data by detecting patterns, trends, and relationships in order to make predictions and ultimately deliver actionable insights to help decision making. Machine learning models can be split into three main types: supervised learning, unsupervised learning, and reinforced learning.

Supervised learning

In supervised learning, the goal is to learn a function that is able to map inputs x to outputs y given a labeled set of input-output pairs D, where D is referred to as the training set and N is the number of input-output pairs in the training set:

In simple applications of supervised...
