We propose a natural cost function for the bi-clustering task, the monochromatic cost. ... This cost function is suitable for detecting meaningful homogeneous bi-clusters based on categorical valued input matrices. ... We also consider the version of the monochromatic bi-clustering in which instead of penalizing nonhomogeneous bi-clusters, we promote bi-cluster homogeneity (or agreement). ...dblp:conf/icml/WulffUB13 fatcat:ayvpaon2bfcqjb7ps4t7ap5flm

Our results show that, for monochromatic distributions, it does not seem to be possible to generate sufficiently intense seed fields in any of the two field generation mechanisms. ... To that end, we consider monochromatic and extended Press-Schechter PBH mass functions, such that each constituent is capable of producing its own magnetic field due to some given physical mechanism. ... This point makes it obvious that δBi is not the value of the magnitude of B at point x, but it is only a statistical tool to derive the clustering statistics and fluctuation spectra of field perturbations ...arXiv:2012.09585v2 fatcat:bjplnfizjnaj7gjwnwdbpetoxq
