These approaches use a local cluster criterion and define clusters as the regions in the data space of higher density compared to the regions of noise points or border points. The data points may be distributed arbitrarily in these regions of high density and may contain ...

Synthetic Datasets for Clustering Algorithms

... The process of grouping similar objects in the given dataset is known as clustering. A large variety of clustering algorithms have been proposed to find clusters in the given dataset. Not many real-life datasets are available for testing the proposed algorithms. Moreover the existing datasets do not ...

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.
