The perhaps the most basic algorithm for clustering, and by far the most used is called K-MEANS. And I’m going to work with you through the algorithm with many, many quizzes for you. Here is our data space. And suppose we are given this type of data. The first question is intuitively, how many clusters do you see? Truth telling, there is not a unique answer, it could be seven it could be one, but give me the answer that seems to make the most sense
