SVD, discrepancy, and regular structure of contingency tables
Marianna Bolla
We will use the factors obtained by correspondence analysis to find biclustering of a contingency table such that the row-column cluster pairs are regular, i.e., they have small di…

Modularity spectra, eigen-subspaces, and structure of weighted graphs
Marianna Bolla
The role of the normalized modularity matrix in finding homogeneous cuts will be presented. We also discuss the testability of the structural eigenvalues and that of the subspace s…
