Aim of Course:

Data mining, the art and science of learning from data, covers a number of different procedures. In this online course, “Predictive Analytics 3 - Dimension Reduction, Clustering, and Association Rules,” you will cover key unsupervised learning techniques: association rules, principal components analysis, and clustering. Predictive Analytics 3 will include an integration of supervised and unsupervised learning techniques.

This is a hands-on course, and participants will apply data mining algorithms to real data.  The course will use R, a free software environment for statistical computing and graphics. It compiles and runs on a wide variety of UNIX platforms, Windows and MacOS.  Note:  If you prefer to work in Excel or Python, this course is offered using Solver (an Excel add-in) or Python.

A final project will integrate an unsupervised task with supervised methods covered in Predictive Analytics 1 - R and Predictive Analytics 2 R (though the unsupervised methods taught in the rest of the course stand on their own and can be studied without having taken those courses).

Anticipated learning outcomes:

  • Understand the issues related to using too many predictors (the "curse of dimensionality")
  • Use principal components analysis to reduce the number of predictors to a smaller number of "components" of correlated predictors
  • Use hierarchical clustering and k-means clustering to find and describe clusters of similar records
  • Use association rules to find patterns of "what goes with what" in transaction data
  • Combine unsupervised and supervised learning methods in a final project
Course Program:

Who Should Take This Course:
Marketers seeking to specify customer segments and identify associations among products purchased, environment scientists seeking to cluster observations, analysts who need to identify the key variables out of many, MBA's seeking to update their knowledge of quantitative techniques, managers and scientists who want to see what data-mining can do, and anyone who wants a practical hands-on grounding in basic data-mining techniques.
Level:
Intermediate/Introductory
Prerequisite:

In addition, there is a lesson in the course where supervised and unsupervised learning techniques are used in combination, so, unless you do not need this portion, you should be familiar with supervised learning methods, such as those presented in Predictive Analytics 1 R.
Organization of the Course:
Options for Credit and Recognition:
Course Text:

The required text for this course is Data Mining for Business Analytics: Concepts, Techniques, and Applications in R, by Shmueli, Patel, Yahav, Bruce and Lichtendahl. This same text is also used in the previous courses: "Predictive Analytics 1 - Machine Learning Tools - with R" and "Predictive Analytics 2 - Neural Nets and Regression - with R".
