Clustering and classification allows you to take a sweeping glance of your data en masse, and then form some logical structures based on what you find there before going deeper into the nuts-and-bolts analysis. In their simplest form, clusters are sets of data points that share similar attributes, and clustering algorithms are the methods that group these data points into different clusters based on their similarities. You’ll see clustering algorithms used for disease classification in medical science, but you’ll also see them used for customer classification i
