biclustering

Biclustering, co-clustering, or two-mode clustering[1] is a data mining technique which allows simultaneous clustering of the rows and columns of a matrix. The term was first introduced by Mirkin[2] (recently by Cheng and Church[3] in gene expression analysis), although the technique was originally introduced much earlier[2] (i.e., by J.A. Hartigan[4]).
Given a set of m rows in n columns (i.e., an m \times n matrix), the biclustering algorithm generates biclusters - a subset of rows which exhibit similar behavior across a subset of columns, or vice versa.
