Congratulations on completing the third chapter of the book! In this chapter, we learned the types of standard probability distribution, as well as when and how to generate them in R. We also learned how to find PDFs and CDFs of unknown distributions with KDE. In the final section, we learned how to compare two samples and determine whether they belong to the same distribution in R. In further chapters, we will learn about other types of unsupervised learning techniques that will help not only in exploratory data analysis but also give us other useful insights into data as well.

Overview of this book
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.
