R Data Mining

Overview of this book

R is widely used to leverage data mining techniques across many different industries, including finance, medicine, scientific research, and more. This book will empower you to produce and present impressive analyses from data, by selecting and implementing the appropriate data mining techniques in R. It will let you gain these powerful skills while immersing in a one of a kind data mining crime case, where you will be requested to help resolving a real fraud case affecting a commercial company, by the mean of both basic and advanced data mining techniques. While moving along the plot of the story you will effectively learn and practice on real data the various R packages commonly employed for this kind of tasks. You will also get the chance of apply some of the most popular and effective data mining models and algos, from the basic multiple linear regression to the most advanced Support Vector Machines. Unlike other data mining learning instruments, this book will effectively expose you the theory behind these models, their relevant assumptions and when they can be applied to the data you are facing. By the end of the book you will hold a new and powerful toolbox of instruments, exactly knowing when and how to employ each of them to solve your data mining problems and get the most out of your data. Finally, to let you maximize the exposure to the concepts described and the learning process, the book comes packed with a reproducible bundle of commented R scripts and a practical set of data mining models cheat sheets.

The data mining engine

The data mining engine is the true heart of our data mining architecture. It consists of tools and software employed to gain insights and knowledge from data acquired from data sources, and stored within data warehouses.

What makes a data mining engine?

As you should be able to imagine at this point, a good data mining engine is composed of at least three components:

  • An interpreter, able to transmit commands defined within the data mining engine to the computer
  • Some kind of gear between the engine and the data warehouse to produce and handle communication in both directions
  • A set of instructions, or algorithms, needed to perform data mining activities

We are going to look a bit closer at these three components, remembering that the most important one, the set of instructions, is actually the theme of the whole book, and will therefore be fully developed throughout all the remaining chapters.

The interpreter

We have actually already met this character before in our story; the...
