Overview of this book

Machine learning is a field of Artificial Intelligence to build systems that learn from data. Given the growing prominence of R—a cross-platform, zero-cost statistical programming environment—there has never been a better time to start applying machine learning to your data. The book starts with introduction to Cross-Industry Standard Process for Data Mining. It takes you through Multivariate Regression in detail. Moving on, you will also address Classification and Regression trees. You will learn a couple of “Unsupervised techniques”. Finally, the book will walk you through text analysis and time series. The book will deliver practical and real-world solutions to problems and variety of tasks such as complex recommendation systems. By the end of this book, you will gain expertise in performing R machine learning and will be able to build complex ML projects using R and its packages.

Text mining framework and methods


There are many different methods to use in text mining. The goal here is to provide a basic framework to apply to such an endeavor. This framework is not all-inclusive of the possible methods but will cover those that are probably the most important for the vast majority of projects that you will work on. Additionally, I will discuss the modeling methods in as succinct and clear a manner as possible because they can get quite a bit complicated. Gathering and compiling the text data is a topic that could take up several chapters. Therefore, let's begin with the assumption that the data is available from Twitter, a customer call center, scraped off the web, or whatever and is contained in some sort of text file or files.

The first task is to put the text files in one structured file referred to as a Corpus. The number of documents could be just one, dozens, hundreds, or even thousands. R can handle a number of raw text files including RSS feeds, pdf files,...
