Truncated nuclear norm minimization for tensor completion

2014 IEEE 8th Sensor Array and Multichannel Signal Processing Workshop (SAM), 2014
In this paper, a tensor n-mode matrix unfolding truncated nuclear norm is proposed, which is extended from the matrix truncated nuclear norm, to tensor completion problem. The alternating direction method of multipliers is utilized to solve this optimization problem.

Principal Component Analysis based on Nuclear norm Minimization

Neural Networks, 2019
Principal component analysis (PCA) is a widely used tool for dimensionality reduction and feature extraction in the field of computer vision. Traditional PCA is sensitive to outliers which are common in empirical applications. Therefore, in recent years, massive efforts have been made to improve the robustness of PCA.

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.

Background subtraction via truncated nuclear norm minimization

2017 Asia-Pacific Signal and Information Processing Association Annual Summit and Conference (APSIPA ASC), 2017
The background subtraction is one of the main topics in video analysis. Among the various conventional approaches related to this topic, low-rank and sparse decomposition based method has shown a great ability to decompose foreground and background. This method approximates the matrix rank by robust principal component analysis via the nuclear norm ...

Nuclear norm minimization for blind subspace identification (N2BSID)

2015 54th IEEE Conference on Decision and Control (CDC), 2015
In many practical applications of system identification, it is not feasible to measure both the inputs applied to the system as well as the output. In such situations, it is desirable to estimate both the inputs and the dynamics of the system simultaneously; this is known as the blind identification problem.

Nuclear norm minimization and tensor completion in exploration seismology

2013 IEEE International Conference on Acoustics, Speech and Signal Processing, 2013
We consider the problem of multidimensional seismic data signal recovery and noise attenuation. These data are multi-dimensional signals that can be described via a low-rank fourth-order tensor in the frequency-space domain. Tensor completion strategies can be used to recover unrecorded observations and to improve the signal-to-noise ratio of seismic ...

Regularization Paths for Re-Weighted Nuclear Norm Minimization

IEEE Signal Processing Letters, 2015
We consider a class of weighted nuclear norm optimization problems with important applications in signal processing, system identification, and model order reduction. The nuclear norm is commonly used as a convex heuristic for matrix rank constraints.

A majorization–minimization weighted soft thresholding algorithm for weighted nuclear norm minimization

International Journal of Machine Learning and Cybernetics, 2014
Matrix completion problem refers to complete a low-rank matrix by observing only a few elements of the matrix. A traditional model to solve this problem is to transfer the minimization of rank into a nuclear norm minimization by replacing the rank function with nuclear norm.

Ultrasound Image Restoration Using Weighted Nuclear Norm Minimization

2020 25th International Conference on Pattern Recognition (ICPR), 2021
Ultrasound images are often contaminated by speckle noise during the acquisition process, which influences the performance of subsequent applications. The paper introduces a nonconvex low-rank matrix approximation model for ultrasound images restoration, which integrates the weighted nuclear norm minimization (WNNM) and data fidelity term.
