Ideal Spatial Adaptation by Wavelet Shrinkage
Minimax estimation sub ject to doing well at a point Orthogonal Wavelet Bases of Compact Support
2015/8/20
With ideal spatial adaptation, an oracle furnishes information about how best to
adapt a spatially variable estimator, whether piecewise constant, piecewise polynomial,
variable knot spline, or vari...
Neo-Classical Minimax Problems, Thresholding, and Adaptation
Minimax Estimation Adaptive Estimation
2015/8/20
We study the problem of estimating from data Y N(; 2
) under squared-error loss.
We de ne three new scalar minimax problems in which the risk is weighted by the size of .
Simple thresholding...
Adaptation and migration of a population between patches
Structured populations phenotypical and spatial structure Hamilton-Jacobi equation viscosity solutions Dirac concentrations stationary solutions
2012/4/23
A Hamilton-Jacobi formulation has been established previously for phenotypical structured population models where the solution concentrates as Dirac masses in the limit of small diffusion. Is it possi...
Joint Relay Selection and Link Adaptation for Distributed Beamforming in Regenerative Cooperative Networks
relay selection link adaptation distributed beamforming signaling throughput
2010/11/26
Relay selection enhances the performance of the cooperative networks by selecting the links with higher capacity.Meanwhile link adaptation improves the spectral efficiency of wireless data-centric net...
An Adaptation of the Scheifele Method to Stiff Systems of Differential Equations
Numerical solutions for perturbed linear ODE systems Stiff problems
2008/11/10
Many branches of Physics and Engineering use perturbed linear ODE's. One method of resolution is based on the use of Scheifele functions for systems. This paper systematically expands three applicatio...
