Cluster Analysis: Basic Concepts and Algorithms

8 Cluster Analysis: Basic Concepts andAlgorithmsCluster analysis divides data into groups (clusters) that are meaningful, useful,or both. If meaningful groups are the goal, then the clusters should capture thenatural structure of the data. In some cases, however, Cluster analysis is only auseful starting point for other purposes, such as data summarization. Whetherfor understanding or utility, Cluster analysis has long played an importantrole in a wide variety of fields: psychology and other social sciences, biology,statistics, pattern recognition, information retrieval, machine learning, anddata have been many applications of Cluster analysis to practical prob-lems.

The Calculusof Variations

www-users.cse.umn.edu

The history of the calculus of variations is tightly interwoven with the history of math-ematics, [12]. The field has drawn the attention of a remarkable range of mathematical luminaries, beginning with Newton and Leibniz, then initiated as a subject in its own right by the Bernoulli brothers Jakob and Johann. The first major developments ...
