Monochromatic Bi-Clustering

Sharon Wulff, Ruth Urner, Shai Ben-David
2013 International Conference on Machine Learning  
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).  ...

Algorithms for the ferromagnetic Potts model on expanders [article]

Charlie Carlson, Ewan Davies, Nicolas Fraiman, Alexandra Kolla, Aditya Potukuchi, Corrine Yap
2022 arXiv   pre-print
It is #BIS-hard to approximate the partition function at low temperatures on bounded-degree graphs, so our algorithm can be seen as evidence that hard instances of #BIS are rare.  ...  #BIS consists of problems that are equivalent to counting the number of independent sets in bipartite graphs [DGGJ04] , and understanding the complexity of #BIS is a longstanding problem.  ...  Approximating the ferromagnetic Potts model partition function for fixed β is #BIS-hard [GJ12] , and restricted to bounded-degree graphs it is #BIS-hard at low temperatures [G ŠVY16].  ...

2007 Journal of Non-Crystalline Solids  
Contrary to the case of 15-nm thick films, peaks due to crystalline Bi were not observed in X-ray diffraction patterns of as-deposited 0.5-nm thick films.  ...  These results show directly the phase transition of bismuth clusters from semi-metallic nanocrystalline to semiconducting amorphous-like clusters with decreasing size.  ...  The monochromatic light was detected by a PbS detector and a photomultiplier. All measurements were performed at room temperature.  ...

Magnetic field generation from primordial black hole distributions [article]

Ignacio J. Araya, Marcelo E. Rubio, Marco San Martin, Federico A. Stasyszyn, Nelson D. Padilla, Juan Magana, Joaquin Sureda
2021 arXiv   pre-print
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  ...
