A novel interpretation of least squares solution
International Journal of Mathematics and Mathematical Sciences, 1992 We show that the well-known least squares (LS) solution of an overdetermined system of linear equations is a convex combination of all the non-trivial solutions weighed by the squares of the corresponding denominator determinants of the Cramer's rule ...

An Overdetermined System of Transform Equations in Support of Robust DCE-MRI Registration With Outlier Rejection. [PDF]
Tomography, 2016 Quantitative hepatic perfusion parameters derived by fitting dynamic contrast-enhanced (DCE) magnetic resonance imaging (MRI) of liver to a pharmacokinetic model are prone to errors if the dynamic images are not corrected for respiratory motion by image ...

Newton’s method for overdetermined systems of equations [PDF]
Mathematics of Computation, 1999 Complexity theoretic aspects of continuation methods for the solution of square or underdetermined systems of polynomial equations have been studied by various authors. In this paper we consider overdetermined systems where there are more equations than unknowns. We study Newton’s method for such a system.

Reactor activations to constrain astrophysically relevant cross sections [PDF]
EPJ Web of Conferences, 2022 The determination of astrophysically relevant neutron-induced cross sections is particularly difficult when the involved isotopes are radioactive or the cross sections are very small.
