Iterative least squares algorithms for digital filter design.
… the various Iterative Reweighted Least Squares (IRLS) methods used to design Chebyshev and $L\sb{p}$ linear phase FIR filters. Then we focus on the ILS design of IIR filters and filter banks. For the design of Chebyshev IIR filters in the log magnitude sense, we propose a Remez-type IRLS …

Statistical Modeling of Simulation Errors and Their Reduction via Response Surface Techniques
… by iteratively reweighted least squares (IRLS), is used to identify the outliers, which are then repaired by higher fidelity optimizations. The IRLS procedure is applied to the results of the Rosenbrock test problem, and wing structural weight from the structural optimization of the HSCT. …

Risk-modeling tools for designing resilient micro energy grids
… of MEG. Selected independent resilience layers (IRLs) were proposed to achieve a resilient MEG by increasing safety integrity level (SIL). IRLs are applied using co-generation and thermal energy storage (TES) technologies to mitigate the hazards of system failure, increase efficiency, and …

Mathematical Methods for the Approximation of Radar Traces
… an explicit proof for the convergence of the IRLS algorithm proposed by Huber to solve M-type estimates for non-linear approximation problems. Furthermore we derive a blueprint for a method to solve separable, quadratic least squares problems with very few quadratic variables.

Sequential Motion Estimation and Refinement for Applications of Real-time Reconstruction from Stereo Vision
… with an iteratively re-weighted least squares (IRLS) method in order to reject outliers in the 3D matches. The algorithm is shown to be capable of running in real-time correctly, where the majority of processing time is taken by feature extraction and description. The method is shown to …

Time-lapse seismic AVAz in the Stocker Field
… through Iterative Reweighted Least Squares (IRLS) and Cauchy-Gauss method for the calculation of the weights. Using 4D seismic data from the Stocker field, we compute the variation of the AVAz response before and after the hydraulic fracturing treatment and production from the area of …

Some aspects of fitting multinomial models in a GLM framework
… of the iteratively re-weighted least squares (IRLS) algorithm gives for fitting a multinomial regression model is that the calculations only require a program which can handle ordinary least squares and hence can be handled by a range of standard statistical software. The approach in this …
