Least Squares Multi-Window Evolutionary Spectral Estimation

We present a multi–window method for obtaining the time-frequency spectrum of of nonstationary signals such as speech and music. This method is based on optimal combination of evolutionary spectra that are calculated by using multi–window Gabor expansion. The optimal weights are obtained by using a least square estimation method. An error criterion that is the squared distance between a referen...

Convergence analyses of Galerkin least - squares methods

Symmetric advective-di usive forms of the Stokes and incompressible Navier-Stokes equations are presented. The Galerkin least-squares method for advective-di usive equations is used for both systems and is related to other stabilized methods previously studied. The presentation reveals that the convergence analysis for advective-di usive equations, as applied before to a linearized form of the ...

Multivariate calibration with least-squares support vector machines.

This paper proposes the use of least-squares support vector machines (LS-SVMs) as a relatively new nonlinear multivariate calibration method, capable of dealing with ill-posed problems. LS-SVMs are an extension of "traditional" SVMs that have been introduced recently in the field of chemistry and chemometrics. The advantages of SVM-based methods over many other methods are that these lead to gl...

Total least squares methods

1. the use of weighted norms as a measure of the data perturbation size, capturing prior knowledge about uncertainty in the data; 2. the addition of constraints on the perturbation to preserve the structure of the data matrix, motivated by structured data matrices occurring in signal and image processing, systems and control, and computer algebra; 3. the use of regularization in the problem for...
