DOI: 10.1080/02331934.2019.1711080
Abstract: ABSTRACT We study the total least squares (TLS) with a parametric Tikhonov-like regularization. We relax it to a semidefinite programming (SDP) problem and establish a sufficient condition to guarantee the tightness of the SDP relaxation.… read more here.

DOI: 10.1080/10556788.2020.1850720
Abstract: We suppose the existence of an oracle which solves any semidefinite programming (SDP) problem satisfying strong feasibility (i.e. Slater's condition) simultaneously at its primal and dual sides. We note that such an oracle might not… read more here.
