Algorithms and error bounds for multivariate piecewise constant approximation [PDF]
, 2010 We review the surprisingly rich theory of approximation of functions of many vari- ables by piecewise constants. This covers for example the Sobolev-Poincar´e inequalities, parts of the theory of nonlinear approximation, Haar wavelets and tree ...

Beam-space direct localisation using passive arrays with random shape errors
The Journal of Engineering, 2019 Passive localisation with high accuracy is attractive in numerous fields. Beam-space direct position determination (BS-DPD) using antenna arrays is a promising positioning method which possesses both excellent performance and moderate complexity ...

Multiple Initial Point Approach to Solving Power Flows for Monte Carlo Studies
Energies, 2022 Power flow solvers typically start from an initial point of power injection. This paper constructs a system of multiple initial points (SMIP) to enable selection of an appropriate initial point, with the objective to achieve a balanced improvement in the

Approximation theory for matrices [PDF]
Nuclear Physics B - Proceedings Supplements, 2004 We review the theory of optimal polynomial and rational Chebyshev approximations, and Zolotarev's formula for the sign function over the range (ε\leq |z| \leq1). We explain how rational approximations can be applied to large sparse matrices efficiently by making use of partial fraction expansions and multi-shift Krylov space solvers.

A First Approximation to Homotopy Theory [PDF]
Proceedings of the National Academy of Sciences, 1953 Publisher Summary The suspension map, originally introduced by Freudenthal for the study of the homotopy groups of spheres, has proved to be important in general homotopy questions and it has been found that within the suspension range, the situation is simpler than in the general case.

Rule induction based on rough sets from information tables having continuous domains
CAAI Transactions on Intelligence Technology, 2019 Information tables having continuous domains are handled by neighborhood rough sets. Two approximations in complete information tables are extended to handle incomplete information.

Polytopes and $C^1$-convex bodies [PDF]
Discrete Mathematics & Theoretical Computer Science, 2014 The face numbers of simplicial polytopes that approximate $C^1$-convex bodies in the Hausdorff metric is studied. Several structural results about the skeleta of such polytopes are studied and used to derive a lower bound theorem for this class of ...

Universal Function Approximation by Deep Neural Nets with Bounded Width and ReLU Activations
Mathematics, 2019 This article concerns the expressive power of depth in neural nets with ReLU activations and a bounded width. We are particularly interested in the following questions: What is the minimal width w min ( d ) so that ReLU nets of width w ...
