Sentence examples for minimum support gradient from inspiring English sources
minimum support gradient.
In this paper, we propose a minimum support gradient (MSG) stabilizing functional as another possible choice of focusing stabilizer.
In "Regularized magnetotelluric inversion based on a minimum support gradient stabilizing function," Xiang et al. (2017) proposed a new MSG stabilizing function for imaging sharp interfaces for 1-D and 2-D MT inversion.
Thus, considering the advantages and disadvantages of each of these stabilizing functionals, we propose a new stabilizing functional, the minimum support gradient, which is defined as s_{text{MSG}} ({mathbf{m}},beta ) = sumlimits_{i = 1}^{N} {left( {nabla frac{{(m^{(i)} - m_{text{apr}}^{(i)} )}}{{sqrt {(m^{(i)} - m_{text{apr}}^{(i)} )^{2} + beta^{2} } }}} right)^{2} }. (8).
Although past works have proposed functionals that may be suitable for the imaging of a sharp boundary, such as minimum support and minimum gradient support (MGS) functionals, they involve some difficulties and limitations in practice.
In this approach, we calculate the gradient of the model stabilizing functional of the minimum support, which affects both the stability and the sharp boundary focus of the inversion.
The minimum support threshold, [9 values from 5 to 0.01%].
The minimum support value is set to be 0.5.
Reduce the minimum support, and go to step 6. .
These algorithms are based primarily on minimum support and the minimum confidence.
