Clustering can be viewed as a data modeling technique that provides for concise summaries of the data. Clustering is therefore related to many disciplines and plays an important role in a broad range of applications. The applications of clustering usually deal with large datasets and data with many attributes. Exploration of such data is a subject of data mining.

The research paper published by IJSER journal is about A Survey on Data Mining using Clustering Techniques 1. Abstract – Data mining is the practice of automatically searching large stores of data to discover patterns and trends that go beyond simple analysis. Data mining uses sophisticated mathematical algorithms to segment the data and evaluate the probability of future events.

Data min ing is also known as Knowledge Discovery in Data KDD. Basically there are different types related to data mining like Text Mining, W eb Mining, Multimedia Mining, Spatial Mining, Object Mining etc. 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 clusters.

Data mining is evolve d in a multidisciplinary field, including database technology, machine learning, artificial intelligence, neural network, information retrieval, and so on. In principle data mining should be applicable to the different kind of data and databases used in many different applications, including relational databases, transactional databases, data warehouses, object- oriented databases, and special application- oriented databases such as spatial databases, temporal databases, multimedia databases, and time- series databases.

Spatial data mining, also called Spatial mining, is data mining as applied to t he spatial data or spatial databases. Spatial data are the data that have spatial or location component, and they show the information, which is more complex than classical data. A spatial database stores spatial data represents by spatial data types and spatial relationships and among data. Spatial data mining encompasses various tasks.

Grouping Multidimensional Data pp Cite as. Clustering is the division of data into groups of similar objects. In clustering, some details are disregarded in exchange for data simplification. Clustering can be viewed as a data modeling technique that provides for concise summaries of the data.

Clustering is a division of data into groups of similar objects. Representing the data by fewer clusters necessarily loses certain fine details, but achieves simplification. It models data by its clusters. Data modeling puts clustering in a historical perspective rooted in mathematics, statistics, and numerical analysis. From a machine learning perspective clusters correspond to hidden patterns, the search for clusters is unsupervised learning, and the resulting system represents a data concept.

From a practical perspective clustering plays an outstanding role in data mining applications such as scientific data exploration, information retrieval and text mining, spatial database applications, Web analysis, CRM, marketing, medical diagnostics, computational biology, and many others. Clustering is the subject of active research in several fields such as statistics, pattern recognition, and machine learning. This survey focuses on clustering in data mining.

Data mining adds to clustering the complications of very large datasets with very many attributes of different types. This imposes unique computational requirements on relevant clustering algorithms. A variety of algorithms have recently emerged that meet these requirements and were successfully applied to real-life data mining problems. They are subject of the survey.

Survey of Clustering Data Mining Techniques Another approach starts with the definition of objective function depending on a partition. As we have seen sub-section Linkage Metrics , pair-wise distances or similarities can be used to compute measures of iter- and intra-cluster relations.

In iterative improvements such pair-wise computations would be too expensive. Using unique cluster representatives resolves the problem: now computation of objective function becomes linear in N and in a number of clusters. Depending on how representatives are constructed, iterative optimization partitioning algorithms are subdivided into k-medoids and k-means methods.

K-medoid is the most appropriate data point within a cluster that represents it. Representation by k-medoids has two advantages. First, it presents no limitations on attributes types, and, second, the choice of medoids is dictated by the location of a predominant fraction of points inside a cluster and, therefore, it is lesser sensitive to the presence of outliers. In k-means case a cluster is represented by its centroid, which is a mean usually weighted average of points within a cluster.

This works conveniently only with numerical attributes and can be negatively affected by a single outlier.
