Joint estimation and model order selection for one dimensional ARMA models via convex optimization: a nuclear norm penalization approach
Stéphane Chrétien, Tianwen Wei, Basad Ali Hussain Al-sarray
The problem of estimating ARMA models is computationally interesting due to the nonconcavity of the log-likelihood function. Recent results were based on the convex minimization. J…
Convex recovery of tensors using nuclear norm penalization
Stephane Chretien, Tianwen Wei
The subdifferential of convex functions of the singular spectrum of real matrices has been widely studied in matrix analysis, optimization and automatic control theory. Convex anal…
Sensing tensors with Gaussian filters
Stéphane Chrétien, Tianwen Wei
Sparse recovery from linear Gaussian measurements has been the subject of much investigation since the breaktrough papers \cite{CRT:IEEEIT06} and \cite{donoho2006compressed} on Com…
An Overview of the Asymptotic Performance of the Family of the FastICA Algorithms
Tianwen Wei
This contribution summarizes the results on the asymptotic performance of several variants of the FastICA algorithm. A number of new closed-form expressions are presented.
Von Neumann's inequality for tensors
Stéphane Chrétien, Tianwen Wei
For two matrices in , the von Neumann inequality says that their scalar product is less than or equal to the scalar product of their singular spectrum. I…
