TROPHY: Trust Region Optimization Using a Precision Hierarchy
Richard J Clancy, Matt Menickelly, Jan Hückelheim +3
We present an algorithm to perform trust-region-based optimization for nonlinear unconstrained problems. The method selectively uses function and gradient evaluations at different…
A study of scalar optically-pumped magnetometers for use in magnetoencephalography without shielding
Richard J. Clancy, Vladislav Gerginov, Orang Alem +2
Scalar optically-pumped magnetometers (OPMs) are being developed in small packages with high sensitivities. The high common-mode rejection ratio of these sensors allows for detecti…
Approximate maximum likelihood estimators for linear regression with design matrix uncertainty
Richard J Clancy, Stephen Becker
In this paper we consider regression problems subject to arbitrary noise in the operator or design matrix. This characterization appropriately models many physical phenomena with u…
Robust Least Squares for Quantized Data Matrices
Richard Clancy, Stephen Becker
In this paper we formulate and solve a robust least squares problem for a system of linear equations subject to quantization error in the data matrix. Ordinary least squares fails…
