Survey of Different Clustering Algorithms in Data Mining
... Clustering is the basis for any data analysis. Clustering can be done either by three ways partitioned method, hierarchical method or by density based method. In this survey paper we have define these methods. Partitioned clustering method is fast but it is not fast as hierarchical based method. Sph ...

class discovery

Refinement of K-Means Clustering Using Genetic
... The basic reason for our refinement is, in any clustering algorithm the obtained clusters will never give 100% quality. There will be some errors known as mis-clustered. That is, a data item can be wrongly clustered. These kinds of errors can be avoided by using our refinement algorithm. The cluster ...

Human genetic clustering
Human genetic clustering analysis uses mathematical cluster analysis of the degree of similarity of genetic data between individuals and groups in order to infer population structures and assign individuals to groups. These groupings in turn often, but not always, correspond with the individuals' self-identified geographical ancestry. A similar analysis can be done using principal components analysis, which in earlier research was a popular method. Many studies in the past few years have continued using principal components analysis.
