Dimensionality Reduction Using CLIQUE and Genetic
... In a genetic algorithm [17], the representation of a chromosome is required, so as to describe each individual of the population. A chromosome consists of a sequence of genes from certain alphabet. An alphabet generally consists of binary digits (0 and 1). A common technique which is used to represe ...

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.
