R Machine Learning By Example

By: Raghav Bali

Overview of this book

Data science and machine learning are some of the top buzzwords in the technical world today. From retail stores to Fortune 500 companies, everyone is working hard to making machine learning give them data-driven insights to grow their business. With powerful data manipulation features, machine learning packages, and an active developer community, R empowers users to build sophisticated machine learning systems to solve real-world data problems. This book takes you on a data-driven journey that starts with the very basics of R and machine learning and gradually builds upon the concepts to work on projects that tackle real-world problems. You’ll begin by getting an understanding of the core concepts and definitions required to appreciate machine learning algorithms and concepts. Building upon the basics, you will then work on three different projects to apply the concepts of machine learning, following current trends and cover major algorithms as well as popular R packages in detail. These projects have been neatly divided into six different chapters covering the worlds of e-commerce, finance, and social-media, which are at the very core of this data-driven revolution. Each of the projects will help you to understand, explore, visualize, and derive insights depending upon the domain and algorithms. Through this book, you will learn to apply the concepts of machine learning to deal with data-related problems and solve them using the powerful yet simple language, R.

Data mining @social networks

We have traveled quite a distance so far through the chapters of this book, understanding various concepts and learning some amazing algorithms. We have even worked on projects that have applications in our daily lives. In short, we have done data mining without using the term explicitly. Let us now take this opportunity to formally define data mining.

Mining, in the classical sense of the word, refers to the extraction of useful minerals from the Earth (such as coal mining). Put in the context of the information age, mining refers to the extraction of useful information from large pools of data. Thus, if we look carefully, Knowledge Mining or Knowledge Discovery from Data (KDD) seems to be a better representation than the term data mining. As is the case with many keywords, short and sweet catches the attention. Thus, you may find in many places the terms Knowledge Discovery from Data and data mining being used interchangeably, which is rightly so. The process...
