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…

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…

Dynamic Iterative Pursuit
Dave Zachariah, Saikat Chatterjee, Magnus Jansson
For compressive sensing of dynamic sparse signals, we develop an iterative pursuit algorithm. A dynamic sparse signal process is characterized by varying sparsity patterns over tim…
