(It is noted that the weighting in w can be designed according to other criteria while recognizing that this can change the statistical properties of the estimator.) 2.2.3 Generalized least squares The third model form considered is GLS. In GLS, the weighting W is not diagonal and is a ...

The sparsity pattern is assumed to change slowly with time. The key idea of our proposed solution, LS-CS-residual (LS-CS), is to replace compressed sensing (CS) on the observation by CS on the least squares (LS) residual computed using the previous estimate of the support. We bound CS...

(b): The least squares loss function. vanishing gradients. This allows LSGANs to perform more stable during the learning process. This benefit can also be derived from another perspective: as shown in Figure 2, the least squares loss function is flat only at one point, while the sigmoid ...
This simple change does not affect θˆ since σ2 cancels in(3); however, the method of least squares finds (5)σˆLS2=1n−p−1(y−θˆX)TA−1(y−θˆX), while the maximum likelihood procedure finds σˆMLE2=n−p−1nσˆLS2, and for the natural loss ...
