Clustering Part 2: K-means clustering

Clustering data is the act of partitioning observations into groups, or clusters, such that each data point in the subset shares similar characteristics to its corresponding members. Cluster analysis is commonly used in fields that utilize data mining, pattern recognition and machine learning. While MATLAB has several clustering tools included in its arsenal, we’ll take a look at the function kmeans in this tutorial. Following classification of n observations into k clusters, we can use binary classification to investigate the sensitivity and specificity of our clustering.
