On connection between the convolutive and ordinary nonnegative matrix factorizations
A connection between the convolutive nonnegative matrix factorization (NMF) and the conventional NMF has been established. As a result, we can convey arbitrary alternating update rules for NMF to update rules for C...

Investigating Boolean Matrix Factorization
Matrix factorization or factor analysis is an important task helpful than real data. Unfortunately, the methods used for real matrix factorization fail in the latter case. In this paper we focus on the Boo...

Generalized Totally Nonnegative Matrices.
We define a new class of generalized totally nonnegative matrices, shortly GTN-matrices, over a noncommutative ring with identity and a positive part. The class of GTN-matrices is closed under multiplication, every submatrix of a GTN-mat...
