Coding Prony’s method in MATLAB and applying it to biomedical signal filtering
BMC Bioinformatics, 2018 Background The response of many biomedical systems can be modelled using a linear combination of damped exponential functions. The approximation parameters, based on equally spaced samples, can be obtained using Prony’s method and its variants (e.g.

Adaptive Beamforming for Sparse Array Based on Semi-Definite Programming
IEEE Access, 2018 An adaptive beamforming (ABF) technique for sparse receiving arrays with gain/phase uncertainties is proposed. The basic idea of the proposed method is using the compressed sensing theory to estimate directions and amplitudes of the received signals with

Total least-squares EIO model, algorithms and applications
Geodesy and Geodynamics, 2019 A functional model named EIO (Errors-In-Observations) is proposed for general TLS (total least-squares) adjustment. The EIO model only considers the correction of the observation vector, but doesn't consider to correct all elements in the design matrix ...

The multivariate least trimmed squares estimator. [PDF]
In this paper we introduce the least trimmed squares estimator for multivariate regression. We give three equivalent formulations of the estimator and obtain its breakdown point. A fast algorithm for its computation is proposed.

TLS(Total Least Squares)法を用いた航空機の空力微係数の推定
TLS(Total Least Squares)法を用いた航空機の空力微係数の推定目的変数が説明変数と未知係数の積で表される線形モデル方程式を考える。最小2乗法は目的変数のみに計測誤差が含まれると仮定して未知係数を推定する手法であるが、説明変数に計測誤差が含まれる場合、最小2乗法で求めた係数はバイアス誤差を含み、係数の標準偏差は実際より小さく推定される。TLS(全体最小2乗)法は、説明変数および目的変数の双方に計測誤差が含まれると仮定して、未知係数を求める手法である。TLS法は最小2乗法を一般化したものといえる。TLS法によって推定された係数はバイアス誤差を含まず、係数の標準偏差も正しく推定される。本報告書では、まず、TLS法の概念、計算アルゴリズムおよび特性を示し、最小2乗法と比較する。次に、飛行試験データからのTLS法による空力微係数の推定例を示す。 This report ...
