# Applied Unsupervised Learning with R
Starting with the basics, Applied Unsupervised Learning with R explains clustering methods, distribution analysis, data encoders, and features of R that enable you to understand your data better and get answers to your most pressing business questions.
This book begins with the most important and commonly used method for unsupervised learning - clustering - and explains the three main clustering algorithms - k-means, divisive, and agglomerative. Following this, you'll study market basket analysis, kernel density estimation, principal component analysis, and anomaly detection. You'll be introduced to these methods using code written in R, with further instructions on how to work with, edit, and improve R code. To help you gain a practical understanding, the book also features useful tips on applying these methods to real business problems, including market segmentation and fraud detection. By working through interesting activities, you'll explore data encoders and latent variable models.
By the end of this book, you will have a better understanding of different anomaly detection methods, such as outlier detection, Mahalanobis distances, and contextual and collective anomaly detection.
## What you will learn
* Implement clustering methods such as k-means, agglomerative, and divisive
* Write code in R to analyze market segmentation and consumer behavior
* Estimate distribution and probabilities of different outcomes
* Implement dimension reduction using principal component analysis
* Apply anomaly detection methods to identify fraud
* Design algorithms with R and learn how to edit or improve code
### Hardware requirements
For an optimal student experience, we recommend the following hardware configuration:
* Processor: Intel Core i5 or equivalent
* Memory: 4 GB RAM
* Storage: 10 GB available space
### Software requirements
You’ll also need the following software installed in advance:
* OS: Windows 7 SP1 64-bit, Windows 8.1 64-bit or Windows 10 64-bit, Linux(Ubuntu, Debian, Red Hat, or Suse), or the latest version of OS X
* R (3.0.0 or more recent, available for free at https://cran.r-project.org/)
* Browser: Google Chrome or Mozilla Firefox
