The Karhunen-lo Eve Procedure for Gappy Data

چکیده
This paper addresses the problem of using the Karhunen-Lo eve transform with partial data. Given a set of empirical eigenfunctions we show how to recover the modal coeecients for each gappy snapshot by a least-squares procedure. This method gives an unbiased estimate of the data that lay in the gaps and permits gaps to be lled in a reasonable manner. In addition, a scheme is advanced for nding empirical eigenfunctions from gappy data. It is shown numerically that this obtains spectra and eigenfunctions that are close to those obtained from unmarred data.

Karhunen – Loève procedure for gappy data
The problem of using the Karhunen – Lò eve transform with partial data is addressed. Given a set of empirical eigenfunctions , we show how to recover the modal coefficients for each gappy snapshot by a least-squares procedure. This method gives an unbiased estimate of the data that lie in the gaps and permits gaps to be filled in a reasonable manner. In addition , a scheme is advanced for findi...
متن کاملRecursive solution of an inverse heat transfer problem in rapid thermal processing systems
Rapid thermal processing (RTP) is a new technique for performing various wafer fabrication operations such as annealing, oxidation and chemical vapor deposition in a single chamber. The success of the RTP depends on the precise control of wafer temperature by adjusting wall heat ̄ux. In the present investigation, an ecient recursive method is developed to solve the inverse heat transfer proble...
متن کاملInvestigation of Characteristic Measures for the Analysis andSynthesis of Precision - Machined Surfaces 1
Error prediction and control are key factors in precision machining. These factors rely on the development of formal approaches for analyzing and characterizing error sources in manufacturing. One such approach is the development of mathematical measures of precision, where precision, in this context, is deened as surface variations of manufactured part prooles. In this paper, we discuss a nove...
متن کاملAn efficient, high-order perturbation approach for flow in random porous media via Karhunen–Lo eve and polynomial expansions
In this study, we attempt to obtain higher-order solutions of the means and (co)variances of hydraulic head for saturated flow in randomly heterogeneous porous media on the basis of the combination of Karhunen–Lo eve decomposition, polynomial expansion, and perturbation methods. We first decompose the log hydraulic conductivity Y 1⁄4 lnKs as an infinite series on the basis of a set of orthogona...
متن کاملOptimal Linear Feature Transformations Forsemi - Continuous Hidden Markov
Linear discriminant or Karhunen-Lo eve transforms are established techniques for mapping features into a lower dimensional subspace. This paper introduces a uniform statistical framework, where the computation of the optimal feature reduction is formalized as a Maximum-Likelihood estimation problem. The experimental evaluation of this suggested extension of linear selection methods shows a slig...
