Online Hyperparameter-Free Sparse Estimation Method
Dave Zachariah, Petre Stoica
In this paper we derive an online estimator for sparse parameter vectors which, unlike the LASSO approach, does not require the tuning of any hyperparameters. The algorithm is base…

Vandermonde Decomposition of Multilevel Toeplitz Matrices with Application to Multidimensional Super-Resolution
Zai Yang, Lihua Xie, Petre Stoica
The Vandermonde decomposition of Toeplitz matrices, discovered by Carathéodory and Fejér in the 1910s and rediscovered by Pisarenko in the 1970s, forms the basis of modern subspace…

Cramer-Rao bound analog of Bayes rule
Dave Zachariah, Petre Stoica
In this lecture note, we show a general property of the Cramer-Rao bound (CRB) that quantifies the interdependencies between the parameters in a vector. The presented result is val…
