Each clustering problem is based on some kind of “distance” between points A Euclidean space has some number of real-valued dimensions and “dense” points There is a notion of “average” of two points A Euclidean distance is based on the locations of points in such a space

One notion of dissimilarity here is the square of the Euclidean distance 2 the sum of distances of all customers to their “cluster center” (any point in space

Instead of distance, clustering can use similarity • If we standardize points then Euclidean distance is equivalent to using absolute value of correlation as a
