Clustering is a process of partitioning (classification) of data points (observations, patterns) into disjoint groups (clusters) of similar objects. The search for clusters is a method of unsupervised learning, used in many areas, including statistics, machine learning, data mining, operations research, bioinformatics, facility location, and across multiple application areas including genetics, taxonomy, medicine, marketing, finance, and e-commerce. This article presents an overview of clustering methods and reviews the literature related to different clustering algorithms and methods.
