    Qualitative polyline similarity testing with applications to query-by-sketch, indexing and classification
    Download  alpha.uhasselt.be
    We present an algorithm for polyline (and polygon) similarity testing that is based on the double-cross formalism. To determine the degree of similarity between two polylines, the...

    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: For a fixed “forbidden submatrix” B, the question is, given an input matrix A (both A and B have ent...

    Nonnegative Matrix Factorization with Earth Mover's Distance metric
    Download  www.cs.technion.ac.il
    Nonnegative Matrix Factorization (NMF) approximates a given data matrix as a product of two low rank nonnegative matrices, usually by minimizing the L2 or the KL distance between ...

    Mining discrete patterns via binary matrix factorization
    Download  www.public.asu.edu
    Mining discrete patterns in binary data is important for subsampling, compression, and clustering. We consider rankone binary matrix approximations that identify the dominant patt...

    Perturbed preconditioned inverse iteration for operator eigenvalue problems with applications to adaptive wavelet discretization
    Download  www.math.tu-berlin.de
    ABSTRACT. In this paper we discuss an abstract iteration scheme for the calculation of the smallest eigenvalue of an elliptic operator eigenvalue problem. A short and geometric pro...
