Introduction to Hierarchical Clustering with College Scorecard Data
Clustering is an unsupervised machine learning technique where data need not be labeled. The goal of clustering is to find like-items such as similar customers, similar products, or similar students, just to name a few. Popular clustering algorithms include K-means and hierarchical cluster

Hierarchical Clustering 4: the Lance-Williams algorithm
[http://bit.ly/s-link] The Lance-Williams algorithm provides a single, efficient algorithm to implement agglomerative clustering for different linkage types. We go over the algorithm and provide the update equations for single-link, complete-link and average-link definitions of inter-clust

We will look at the fundamental concept of clustering, different types of clustering methods and the weaknesses. Clustering is an unsupervised learning technique that consists of grouping data points and creating partitions based on similarity. The ultimate goal is to find groups of simila

Clustering is an unsupervised machine learning tool to reduce dimensionality and put similar data together. We can do clustering in hierarchical, or partitioning approaches, but we need a distance metric that follows some basic rules. In this video we discuss clustering, measuring distance
