Connections Between Nuclear-Norm and Frobenius-Norm-Based Representations [PDF]

open access: yesIEEE Transactions on Neural Networks and Learning Systems, 2018
A lot of works have shown that frobenius-norm based representation (FNR) is competitive to sparse representation and nuclear-norm based representation (NNR) in numerous tasks such as subspace clustering. Despite the success of FNR in experimental studies, less theoretical analysis is provided to understand its working mechanism.

Frobenius Norm based 2DPCA

2020 IEEE 4th Information Technology, Networking, Electronic and Automation Control Conference (ITNEC), 2020
PCA is a classical feature extraction method. But PCA usually loses the structure information of the image. As the tensor version of PCA, 2DPCA could save the structure information and could be fast calculated. However, both PCA and 2DPCA utilize the square of Frobenius norm to describe the total scatter, which enlarges the influence of the outliers ...

The Extremum of the Frobenius Norm of Matrix

2011 Fourth International Joint Conference on Computational Sciences and Optimization, 2011
For two given matrices A and B, the extremum of the Frobenius norm of matrix B-XA is established when X is running all over the unitary matrices. By using the technique of singular value decomposition, the extremum of the Frobenius norm matrix is studied. The result shows that the matrix B-XA has extremum when X is running all over the unitary matrices

Is the Frobenius matrix norm induced?

IEEE Transactions on Automatic Control, 1995
Remind that the Frobenius norm of the matrix \(A\) with the items \(A_{\mu\nu}\) is \((\sum_\mu \sum_nu|A_{\mu\nu}|^2)^{1/2}\). From the authors' abstract: ``using the notion of dual norms we show that, up to a scalar multiple, the maximum singular value is the only unitarily invariant induced norm. As a special case of this result, it follows that the

Probabilistic Analysis of an Estimator for the Frobenius Norm of a Matrix Product

open access: yesJSIAM Letters, 2017
Summary: Estimating the Frobenius norm of a matrix product \(C=XY\) without computing \(C\) explicitly is required in applications such as the one-sided block Jacobi method. In this paper, we analyze \textit{M. Bečka} et al.'s [Parallel Comput. 28, No.

Frobenius norm minimization and probing for preconditioning

International Journal of Computer Mathematics, 2007
In this paper we introduce a new method for defining preconditioners for the iterative solution of a system of linear equations. By generalizing the class of modified preconditioners (e.g. MILU), the interface probing, and the class of preconditioners related to the Frobenius norm minimization (e.g.

Joint Frobenius norm and reweighted nuclear norm minimization for interference alignment

2013 IEEE International Conference on Communications (ICC), 2013
This paper considers a K-user multiple-input multiple-output (MIMO) interference channel in which uncoordinated interference appears. Due to the uncoordinated interference, perfect interference alignment (IA) may be not attained, which indicates the interference subspaces can not be completely aligned.
