k-means clustering is a method of vector quantization, originally from signal processing, that aims to partition n observations into k clusters in which each observation belongs to the cluster with the nearest mean (cluster centers or cluster centroid), serving as a prototype of the cluster. This results in a … See more The term "k-means" was first used by James MacQueen in 1967, though the idea goes back to Hugo Steinhaus in 1956. The standard algorithm was first proposed by Stuart Lloyd of Bell Labs in 1957 as a technique for See more Three key features of k-means that make it efficient are often regarded as its biggest drawbacks: • Euclidean distance is used as a metric and variance is used as a measure of cluster scatter. • The number of clusters k is an input parameter: an … See more Gaussian mixture model The slow "standard algorithm" for k-means clustering, and its associated expectation-maximization algorithm, is a special case of a Gaussian … See more Different implementations of the algorithm exhibit performance differences, with the fastest on a test data set finishing in 10 seconds, the slowest taking 25,988 seconds (~7 hours). The differences can be attributed to implementation quality, language and … See more Standard algorithm (naive k-means) 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. … See more k-means clustering is rather easy to apply to even large data sets, particularly when using heuristics such as Lloyd's algorithm. It has been successfully used in market segmentation See more The set of squared error minimizing cluster functions also includes the k-medoids algorithm, an approach which forces the center … See more WebAug 8, 2024 · KMeans clustering is an Unsupervised Machine Learning algorithm that does the clustering task. In this method, the ‘n’ observations are grouped into ‘K’ clusters based on the distance. The algorithm tries to minimize the within-cluster variance (so that similar observations fall in the same cluster).
