The Bethe Permanent of a Non-Negative Matrix
Bethe approximation Bethe permanent graph cover partition function perfect matching permanent sumproduct algorithm
2011/9/16
Abstract: It has recently been observed that the permanent of a non-negative square matrix, i.e., of a square matrix containing only non-negative real entries, can very well be approximated by solving...
An Interpretation of the Moore-Penrose Generalized Inverse of a Singular Fisher Information Matrix
Cramer-Rao bound constrained parameters singular Fisher information matrix
2011/9/1
Abstract: An interpretation of the Moore-Penrose generalized inverse of a singular Fisher information matrix (FIM) is presented in this paper, from the perspective of Cramer-Rao bound (CRB). CRB is a ...
Decoding of Matrix-Product Codes
Linear Codes Matrix-Product Codes Decoding Algorithm Minimum Distance

Abstract: We propose a decoding algorithm for the $(u\mid u+v)$-construction that decodes up to half of the minimum distance of the linear code. We extend this algorithm for a class of matrix-product ...
Google matrix and Ulam networks of intermittency maps
Google matrix Ulam networks intermittency maps
2010/4/8
We study the properties of the Google matrix of an Ulam network generated by intermittency maps. This network is created by the Ulam method which gives a matrix approximant for the Perron-Frobenius op...
