Whether for understanding or utility, cluster analysis has long played an important role in a wide variety of fields: psychology and other social sciences, biology, statistics, pattern recognition, information retrieval, machine learning, and data mining. There have been many applications of cluster analysis to practical prob-.
Tan,Steinbach, Kumar. Introduction to Data Mining. 4/18/2004. 2. What is Cluster Analysis? 0 Finding groups of objects such that the objects in a group will be similar (or related) to one another and different from (or unrelated to) the objects in other groups. Inter-cluster distances are maximized. Intra-cluster distances are.

What is Clustering? A cluster of data objects can be treated as a one group. While doing the cluster analysis, we first partition the set of data into groups based on data similarity and then assign the label to the groups.
Cluster Analysis in Data Mining from University of Illinois at Urbana-Champaign. Discover the basic concepts of cluster analysis, and then study a set of typical clustering methodologies, algorithms, and applications. This includes partitioning

Hierarchical Agglomerative Clustering. • Evaluation of clusters. • Large data mining perspective. • Practical issues: clustering in Statistica and Stefanowski 2008. Cluster Analysis. Astronomy - aggregation of stars, galaxies, or super galaxies, . Stefanowski 2008. Yet another categorization. • Following Jain's tutorial.
Regarding to data mining, this metodology partitions the data implementing a specific join algorithm, most suitable for the desired information analysis. This clustering analysis allows an object not to be part of a cluster, or strictly belong to it, calling this type of grouping hard partitioning. In the other hand, soft partitioning
