On Genetic Algorithms for Boolean Matrix Factorization
Matrix factorization or factor analysis is an important task in the analysis of high dimensional real world data. There are several well known methods and algorithms for factorization of real data but they are rath...

A Study of Boolean Matrix Factorization Under Supervised Settings
Boolean matrix factorization is a generally accepted approach used in data analysis to explain data or for data preprocessing in the supervised settings. In this paper we study factors in the supervised settings. We provide...

Factorizable matrices
We study square matrices which are products of simpler factors with the property that any ordering of the factors yields a matrix cospectral with the given matrix. The results generalize those obtained previously b...

Basic Matrices.
We define a basic matrix as a square matrix which has both subdiagonal and superdiagonal rank at most one. We investigate, partly using additional restrictions, the relationship of basic matrices to factorizations. Special ...
