Pearson information-based lower bound on Fisher information
Dave Zachariah, Petre Stoica
The Fisher information matrix (FIM) plays an important role in the analysis of parameter inference and system design problems. In a number of cases, however, the statistical data d…
Sparse Methods for Direction-of-Arrival Estimation
Zai Yang, Jian Li, Petre Stoica +1
Direction-of-arrival (DOA) estimation refers to the process of retrieving the direction information of several electromagnetic waves/sources from the outputs of a number of receivi…
Recursive nonlinear-system identification using latent variables
Per Mattsson, Dave Zachariah, Petre Stoica
In this paper we develop a method for learning nonlinear systems with multiple outputs and inputs. We begin by modelling the errors of a nominal predictor of the system using a lat…
Prediction performance after learning in Gaussian process regression
Johan Wågberg, Dave Zachariah, Thomas B. Schön +1
This paper considers the quantification of the prediction performance in Gaussian process regression. The standard approach is to base the prediction error bars on the theoretical…
Scalable and Passive Wireless Network Clock Synchronization
Dave Zachariah, Satyam Dwivedi, Peter Händel +1
Clock synchronization is ubiquitous in wireless systems for communication, sensing and control. In this paper we design a scalable system in which an indefinite number of passively…
