In many modern data mining applications, such as analysis of gene expression or worddocument data sets, the data is highdimensional with hundreds or even thousands of variables, unstructured with no specific order of the original variables, and noisy. Despite the high dimensionality, the data is typically redundant with underlying structures that can be represented by only a few features. In such settings and specifically when the number of variables is much larger than the sample size… CONTINUE READING
