Introduction to clustering: the KMeans algorithm (with Java code)
In this blog post, I will introduce the popular data mining task of clustering (also called cluster analysis). I will explain what is the goal of clustering, and then introduce the popular KMeans algorithm with an example. Moreover, I will briefly explain how an opensource Java implementation of … Continue reading
