Geometric approaches to matrix normalization and graph balancing

Forum of Mathematics, Sigma
Normal matrices, or matrices which commute with their adjoints, are of fundamental importance in pure and applied mathematics. In this paper, we study a natural functional on the space of square complex matrices whose global minimizers are normal ...

Acceleration of Convergence in Dontchev’s Iterative Method for Solving Variational Inclusions [PDF]

, 2003
2000 Mathematics Subject Classification: 47H04, 65K10.In this paper we investigate the existence of a sequence (xk ) satisfying 0 ∈ f (xk )+ ∇f (xk )(xk+1 − xk )+ 1/2 ∇2 f (xk )(xk+1 − xk )^2 + G(xk+1 ) and converging to a solution x∗ of the generalized

A high-accuracy differential quadrature method with optimized spline basis for Burgers’ equation

Mathematical and Computer Modelling of Dynamical Systems
In this study, a new numerical approach is presented by combining the differential quadrature method with particle swarm optimization for an efficient solution of nonlinear partial differential equations. The proposed methodology is illustrated using the

Instability in deep learning – when algorithms cannot compute uncertainty quantifications for neural networks

European Journal of Applied Mathematics
In deep learning, interval neural networks are used to quantify the uncertainty of a pre-trained neural network. Suppose we are given a computational problem $P$ and a pre-trained neural network $\Phi _P$ that aims to solve $P$ .

GENERALIZED NONLINEAR VARIATIONAL INEQUALITIES [PDF]

, 2014
. In this paper, we consider a generalized nonlinear variational inequality problem involving single valued and multivalued nonlinear operators. We also study criteria of its solvability. Iterative methods for approximate solution are also proposed and a
