Certify and Increase Opportunity. Be Govt. Certified Data Mining and Warehousing Role in Data mining. Cluster analysis or clustering is the task of assigning a set of objects into groups (called clusters) so that the objects in the same cluster are more similar (in some sense or another) to each other than to those in other
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
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.
useful starting point for other purposes, such as data summarization. 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.

Cluster analysis or clustering is the task of grouping a set of objects in such a way that objects in the same group (called a cluster) are more similar (in some sense) to each other than to those in other groups (clusters). It is a main task of exploratory data mining, and a common technique for statistical data analysis, used in
