Biclustering, block clustering, Co-clustering or two-mode clustering is a data mining technique which allows simultaneous clustering of the rows and columns of a matrix. The term was first introduced by Boris Mirkin to name a technique introduced many years earlier, in 1972, by J. A. Hartigan. Given a … See more Biclustering was originally introduced by J. A. Hartigan in 1972. The term "Biclustering" was then later used and refined by Mirkin. This algorithm was not generalized until 2000, when Y. Cheng and G. M. Church … See more Bicluster with constant values (a) When a Biclustering algorithm tries to find a constant-value Bicluster, it reorders the rows and columns of the matrix to group together similar rows and columns, eventually grouping Biclusters with similar values. This … See more • FABIA: Factor Analysis for Bicluster Acquisition, an R package —software See more The complexity of the Biclustering problem depends on the exact problem formulation, and particularly on the merit function used to evaluate the quality of a given Bicluster.
