Web12 apr. 2024 · Matrix nearness problems have deserved the attention of researchers; see, e.g., [ 8, 16, 17, 29] and references therein. For instance, distance measures to the algebraic variety of normal matrices have received remarkable attention; see [ … WebSecondly, a general scheme for orthogonal matrix nearness problems under any unitarily invariant norm is addressed and the corresponding iterative algorithm is proposed. Thirdly, feature representation problems are formulated as certain forms of orthogonal matrix nearness, indicating a joint framework for learning low-dimensional features with closed …
Regularization matrices determined by matrix nearness problems
Webapplications of proximal optimization methods in learning problems. 2 Characterization of the proximity operator via matrix nearness In this section we characterize the proximity operator of ˚in terms of the root of a univariate function. This is achieved by showing that the dual of the optimization problem involved with the operator is a WebGeneralized frame operator distance problems. × Close Log In.
