Date of Online Publication: 22/12/2006 Keywords: multivariate numerical integration, quadrature, cubature, lattice rules Authors: R. Cools, D. Nuyens Pages: 257-272 An overview is presented of the role played by structured matrices in the construction of lattice rules for numerical integration. Two methods which make use of (skew-)circulant matrices are discussed. The first method is for […]

Abstract: Algorithm-based computers are programmed, i.e., there must be a set of rules which, a priori, characterize the calculation that is implemented by the computer. Neural computation, based on neural networks, solve problems by learning, they absorb experience, and modify their internal structure in order to accomplish a given task. In the learning process, the
