Primitive Zero-Symmetric Sign Pattern Matrices with Zero Diagonal Attaining the Maximum Base
A sign pattern matrix or sign pattern A is a matrix whose entries are from the set {1,−1, 0}. Notice that for a square sign pattern matrixA, in the computation of the signs of the entries of the power A, an ambiguous sign may arise when a positive sign is added to a negative sign. So a new symbol # was introduced in 1 to denote such an ambiguous sign. The powers of a square sign pattern have be...
متن کاملMinimum Rank, Maximum Nullity, and Zero Forcing of Graphs
Combinatorial matrix theory, which involves connections between linear algebra, graph theory, and combinatorics, is a vital area and dynamic area of research, with applications to fields such as biology, chemistry, economics, and computer engineering. One area generating considerable interest recently is the study of the minimum rank of matrices associated with graphs. Let F be any field. For a...
متن کاملEla Positive Semidefinite Maximum Nullity and Zero Forcing Number
The zero forcing number Z(G) is used to study the minimum rank/maximum nullity of the family of symmetric matrices described by a simple, undirected graph G. The positive semidefinite zero forcing number is a variant of the (standard) zero forcing number, which uses the same definition except with a different color-change rule. The positive semidefinite maximum nullity and zero forcing number f...
متن کاملMaximum Expected Likelihood Estimation for Zero-resource Neural Machine Translation
While neural machine translation (NMT) has made remarkable progress in translating a handful of resource-rich language pairs recently, parallel corpora are not always readily available for most language pairs. To deal with this problem, we propose an approach to zero-resource NMT via maximum expected likelihood estimation. The basic idea is to maximize the expectation with respect to a pivot-to...
متن کاملMaximum-likelihood compensation of zero-memory nonlinearities in speech signals
In this paper, an algorithm to blindly compensate zero-memory nonlinear distortions of speech waveforms is derived and analyzed. This method finds a maximum-likelihood estimate of the distortion without a priori knowledge of the microphone characteristics by using the expectation-maximization algorithm. The autoregressive signal model coefficients are solved jointly with the nonlinearity estima...
