WebApr 9, 2024 · The K-Means algorithm at random uniformly selects K points as the center of mass at initialization, and in each iteration, calculates the distance from each point to the K centers of mass, divides the samples into the clusters corresponding to the closest center of mass, and at the same time, calculates the mean value of all samples within each … 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 proceeds …
