Weighted SPICE: A Unifying Approach for Hyperparameter-Free Sparse Estimation
Petre Stoica, Dave Zachariah, Jian Li
In this paper we present the SPICE approach for sparse parameter estimation in a framework that unifies it with other hyperparameter-free methods, namely LIKES, SLIM and IAA. Speci…

Estimation for the Linear Model with Uncertain Covariance Matrices
Dave Zachariah, Nafiseh Shariati, Mats Bengtsson +2
We derive a maximum a posteriori estimator for the linear observation model, where the signal and noise covariance matrices are both uncertain. The uncertainties are treated probab…
