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....
In particular, Black–Scholes are able to use the riskless hedge portfolio construction to provide an additional condition that permits elimination of the dW term. In this fashion, the call option pricing problem is transformed from an SDE problem that is not solvable in closed form with standard...
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...

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...

In contrast to (Zhou et al., 2019), this elimination of downsampling allows us to ignore: 2.2. Binary masks to 2D Gaussian masks conversion Usually, for a dataset of polyp images, binary masks f(x,y)∈{0,1}W×H×1, are provided as the ground-truth images to indicate the location ...
