The Sample Size Influence in the Accuracy of the Image Classification of the Remote Sensing [PDF]
Revista Brasileira de Cartografia, 2004 Landuse/landcover maps produced by classification of remote sensing images incorporate uncertainty. This uncertainty is measured by accuracy indices using reference samples.

Chebyshev Collocation Method for Parabolic Partial Integrodifferential Equations
Advances in Mathematical Physics, 2016 An efficient technique for solving parabolic partial integrodifferential equation is presented. This technique is based on Chebyshev polynomials and finite difference method. A priori error estimate for the proposed technique is deduced.

Multiadaptive Galerkin Methods for ODEs III: A Priori Error Estimates [PDF]
SIAM Journal on Numerical Analysis, 2006 The multiadaptive continuous/discontinuous Galerkin methods mcG(q) and mdG(q) for the numerical solution of initial value problems for ordinary differential equations are based on piecewise polynomial approximation of degree q on partitions in time with time steps which may vary for different components of the computed solution. In this paper, we prove

A priorierror estimates for a state-constrained elliptic optimal control problem [PDF]
ESAIM: Mathematical Modelling and Numerical Analysis, 2012 We examine an elliptic optimal control problem with control and state constraints in R 3 . An improved error estimate of O(h s )w ith 3 ≤ s ≤ 1−e is proven for a discretisation involving piecewise constant functions for the control and piecewise linear for the state. The derived order of convergence is illustrated by a numerical example.

International Journal of Adaptive Control and Signal Processing, EarlyView.This paper proposes two projector‐based Hopfield neural network (HNN) estimators for online, constrained parameter estimation under time‐varying data, additive disturbances, and slowly drifting physical parameters. The first is a constraint‐aware HNN that enforces linear equalities and inequalities (via slack neurons) and continuously tracks the ...

Error Evaluation in a Stereovision-Based 3D Reconstruction System
EURASIP Journal on Image and Video Processing, 2010 The work presented in this paper deals with the performance analysis of the whole 3D reconstruction process of imaged objects, specifically of the set of geometric primitives describing their outline and extracted from a pair of images knowing their ...

Nuclear Binding Energies and NN uncertainties
, 2012 There is an increasing interest in quantifying the predictive power in nuclear structure calculations. We discuss how both experimental and systematic errors at the NN-level can be used to estimate the theoretical uncertainties by rather simple means and

Contact Lens with Moiré Patterns for High‐Precision Eye Tracking
Advanced Functional Materials, EarlyView.This work presents a passive contact lens for high‐precision eye tracking, integrating a microscopic moiré grating label. The parallax‐induced shift of macroscopic moiré patterns enables angle measurement with 0.28° precision using a standard camera under ambient light.
