WebThe most widely used criterion for the K-means algorithm is the SSE [5]: SSE = PK j=1 P xi∈Cj kxi −µjk2, where µj = 1 nj P xi∈Cj xi denotes the mean of cluster Cj and nj denotes the number of instances in Cj. K-means starts with initialK centroids (means), then it … The most common algorithm uses an iterative refinement technique. Due to its ubiquity, it is often called "the k-means algorithm"; it is also referred to as Lloyd's algorithm, particularly in the computer science community. It is sometimes also referred to as "naïve k-means", because there exist much faster alternatives. Given an initial set of k means m1 , ..., mk (see below), the algorithm proceed…
