WebJan 20, 2024 · Clustering is an unsupervised machine-learning technique. It is the process of division of the dataset into groups in which the members in the same group possess similarities in features. ... Again reassign the … 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… WebThe "assignment" step is referred to as the "expectation step", while the "update step" is a maximization step, making this algorithm a variant of the generalized expectation-maximization algorithm.
