摘要
A computer system for partitioning the columns of a matrix A. The computer system includes a processor and a memory unit coupled to the processor. Program code in the memory unit, when executed by the processor, implements the method. Matrix A is provided in a memory device and has n columns and m rows; wherein n is an integer of at least 3; and wherein m is an integer of at least 1. The n columns is partitioned into a closed group of p clusters, p being a positive integer of at least 2 and less than n. The partitioning includes an affinity -based merging of clusters of pairs of clusters of the matrix A based on an affinity between the clusters in each pair of clusters being merged. Each cluster consists of one or more columns of matrix A. The p clusters are stored in a computer-readable storage device.
