WebThis work studies the Generalized Singular Value Thresholding (GSVT) operator associated with a nonconvex function g defined on the singular values of X. We prove that GSVT can be obtained by performing the proximal operator of g (denoted as Proxg(·)) on the singular values since Proxg(·) is monotone when g is lower bounded.
WebFeb 18, 2015 · This work studies the Generalized Singular Value Thresholding (GSVT) operator associated with a nonconvex function g defined on the singular values of X. We prove that GSVT can be obtained by performing the proximal operator of g on the singular values since Proxg (.) is monotone when g is lower bounded. WebTo do so, we establish that PCR is equivalent to performing linear regression after preprocessing the covariate matrix via hard singular value thresholding (HSVT). As a result, in the context of counterfactual analysis using observational data, we show PCR is equivalent to the recently proposed robust variant of the synthetic control method ...
