Parameter estimation in spherical symmetry groups
Yu-Hui Chen, Dennis Wei, Gregory Newstadt +3
This paper considers statistical estimation problems where the probability distribution of the observed random variable is invariant with respect to actions of a finite topological…
Resource-Constrained Adaptive Search for Sparse Multi-Class Targets with Varying Importance
Gregory E. Newstadt, Beipeng Mu, Dennis Wei +2
In sparse target inference problems it has been shown that significant gains can be achieved by adaptive sensing using convex criteria. We generalize previous work on adaptive sens…
Spectral Correlation Hub Screening of Multivariate Time Series
Hamed Firouzi, Dennis Wei, Alfred O. Hero
This chapter discusses correlation analysis of stationary multivariate Gaussian time series in the spectral or Fourier domain. The goal is to identify the hub time series, i.e., th…
Resource-Constrained Adaptive Search and Tracking for Sparse Dynamic Targets
Gregory E. Newstadt, Dennis L. Wei, Alfred O. Hero
This paper considers the problem of resource-constrained and noise-limited localization and estimation of dynamic targets that are sparsely distributed over a large area. We genera…
