— This work proposes a novel method of matrix factorization on the complex domain to obtain both intuitive features and high recognition results in a face recognition system. The real data matrix is transformed into a complex number based on the Euler representation of complex numbers. Base complex matrix factorization (CMF) is developed and two extensions including sparse complex matrix factor...
We develop a computationally less expensive alternative to the direct solution of a large sparse symmetric positive definite system arising from the numerical solution of elliptic partial differential equation models. Our method, substituted factorization , replaces the computationally expensive factorization of certain dense submatrices that arise in the course of direct solution with sparse C...
This paper describes the design and implementation of three core factorization routines | LU, QR and Cholesky | included in the out-of-core extension of ScaLAPACK. These routines allow the factorization and solution of a dense system that is too large to t entirely in physical memory. An image of the full matrix is maintained on disk and the factorization routines transfer sub-matrices into mem...
An iterative predictor-corrector technique for the elimination of the approximate factorization errors which result from the factorization of linearized 0-methods in multidimensional reaction~iiffusion equations is proposed, and its convergence and linear stability are analyzed. Four approximate factorization techniques which do not account for the approximate factorization errors are developed...
Lack of deficiency of information in different particular areas like science, engineering as well as bio informatics has several problems. To overcome these issues, proposed a system and that system fusioning different kind of information inside single or individual unit for the preference or for the research of different existing areas. There is information fusioning is achieved through the ma...
