Geometric approaches to matrix normalization and graph balancing

open access: yesForum 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]

open access: yes, 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

open access: yesMathematical 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

open access: yesEuropean 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 $P$ .

An MBO method for modularity optimisation based on total variation and signless total variation

open access: yesEuropean Journal of Applied Mathematics
In network science, one of the significant and challenging subjects is the detection of communities. Modularity [1] is a measure of community structure that compares connectivity in the network with the expected connectivity in a graph sampled from a ...
