Abstract:Biclustering is a problem to detect homogeneous submatrices in a given observed matrix, and it has been shown to be an effective tool for relational data analysis. Although there have been many studies for estimating the underlying bicluster structure of a matrix, few have enabled us to determine the appropriate number of biclusters in an observed matrix. Recently, a statistical test on the number of biclusters has been proposed for a regular-grid bicluster structure, where we assume that the latent bicluster … Show more
