Introduction to the Course and Welcome!
Instructor Welcome and Background
In this short video, I talk about where you can get various data sets for exploration.
In this lecture, we provide a brief background of clustering and typical real-world applications.
This video lecture discusses a real-world, specific example of how I used the College Scorecard data to create clusters. The customer success team absolutely loves the visualization and uses it weekly to develop success strategies for the customers the serve.
In this lecture, I go over the need for scaling or normalizing the data as part of a clustering analysis.
This lecture discusses how hierarchical clustering (also called agglomerative hierarchical clustering) can be used to place institutions into clusters. This is a great analysis to understand how institutions differ or are similar, especially for students examining which college or university to attend.
In this lecture, I talk about how easy it is to run a kMeans clustering analysis after you have prepped and cleansed your data.
In this lecture, I review one method for determining the optimal number of clusters you can use for your clustering analysis. YMMV and keep in mind results are suggestions, not hard-and-fast rules.
In this lecture, I discuss the ideas behind dimensionality reduction.
This quiz is about dimensionality reduction.
In this lecture (parts 1 and 2), I introduce you to the ideas around association rule mining and frequent itemset mining. This is a powerful unsupervised learning technique that, I believe, doesn't get enough attention. Make sure you have this one in your toolbelt!
This is Part 2 of the Introduction to Frequent Itemset Mining and Association Rule Mining
In this lecture, I discuss some of the metrics/measures you can use to interpret association rules.
In this lecture, I show you how to get and display the frequent itemsets.
In this lecture, I show you how to get the association rules, display them, and a little bit of interpretation.
So, you have your itemsets and rules results. Next, sort them by support or lift to examine some of the more "interesting" rules. You will have to experiment a bit.
This will test your knowledge of FIM and AR.
