A backward stable algorithm gives an exact answer to a nearly right question. Gaussian elimination在前向消元之后, system显然又被引入了各种误差, 是一个perturbed system. 但是一个backward stable algorithm可以确保backward 过程获得的解是exact的(针对这个perturbed system). 显然backward stability强于stability....

1.2 Gaussian Elimination Row-Echelon Form ? In 1.1, we worked on manipulating an augmented matrix using elementary row operations so that our resulting equations could easily be solved for the values of the variables. ? Our Goal was to get the augmented matrix into Row-Echelon Form: – All ...

Curated list of papers and resources focused on 3D Gaussian Splatting, intended to keep pace with the anticipated surge of research in the coming months. - MrNeRF/awesome-3D-gaussian-splatting
This method — which Euler did not recommend, which Legendre called "ordinary," and which Gauss called "common" — is now named after Gauss: "Gaussian" elimination. Gauss's name became associated with elimination through the adoption, by professional computers, of a specialized notation that ...
There are several factors that lead to the absence of high partial correlations between interacting metabolites, that is false negative edges in the GGM: (a) Counterantagonistic correlation-generating processes and bimolecular reactions (see above) might lead to the elimination of pairwise association...
Elimination of 180° phase shifts in OQPSK offers many advantages over QPSK. Unlike QPSK, the spectrum of OQPSK remains unchanged when band-limited [1]. Additionally, OQPSK performs better than QPSK when subjected to phase jitters [2]. Further improvements to OQPSK can be obtained if the phas...
