A Review Paper on Clustering in Data Mining

Clustering is a process of keeping similar data intogroups. Objects within the cluster/group have high similarity in comparison to one another but are very dissimilar to objects of other clusters. Clustering is an unsupervised learningtechnique as every other problem of this kind; it dealswith finding a structure in a collection of unlabeleddata. Types of clustering methods are-hierarchical and partitioningbased. Inthis paper clustering and its methodsare discussed.
