We norm (defined as the limit of an L<Subscript>p</Subscript> norm as p approaches zero).

However, K-modes is an order of magnitude faster...</subscript>

Due to recent interest in the analysis of DNA microarray data, new methods have been considered and developed in the area of statistical classification. In particular, according to the gene expression profile of existing data, the goal is to classify the sample into a relevant diagnostic...
