    The Computational Complexity of Avoiding Forbidden Submatrices by Row Deletions
    Download  theinf1.informatik.uni-jena.de
    We initiate a systematic study of the Row Deletion(B) problem on matrices: Given an input matrix A and a fixed "forbidden submatrix" B, the task is to remove a minimum n...

    SVD based initialization: A head start for nonnegative matrix factorization
    Download  www.cs.rpi.edu
    We describe Nonnegative Double Singular Value Decomposition (NNDSVD), a new method designed to enhance the initialization stage of nonnegative matrix factorization (NMF). NNDSVD c...

    On the Uniqueness of Nonnegative Sparse Solutions to Underdetermined Systems of Equations
    Download  www.cs.technion.ac.il
    An underdetermined linear system of equations Ax = b with non-negativity constraint x 0 is considered. It is shown that for matrices A with a row-span intersecting the positive o...
