Runge-Kutta Approximations for Direct Coning Compensation Applying Lie Theory
John A. Christian, Michael R. Walker, Wyatt Bridgman +1
The integration of gyroscope measurements is an essential task for most navigation systems. Modern vehicles typically use strapdown systems, such that gyro integration requires con…
Detecting Outbreaks Using a Latent Field: Part II -- Scalable Estimation
Wyatt Bridgman, Cosmin Safta, Jaideep Ray
In this paper, we explore whether the infection-rate of a disease can serve as a robust monitoring variable in epidemiological surveillance algorithms. The infection-rate is depend…
Detecting Outbreaks Using a Latent Field: Part I -- Spatial Modeling
Cosmin Safta, Wyatt Bridgman, Jaideep Ray
In this paper, we develop a method to estimate the infection-rate of a disease, over a region, as a field that varies in space and time. To do so, we use time-series of case-counts…
Enhancing Polynomial Chaos Expansion Based Surrogate Modeling using a Novel Probabilistic Transfer Learning Strategy
Wyatt Bridgman, Uma Balakrishnan, Reese Jones +5
In the field of surrogate modeling, polynomial chaos expansion (PCE) allows practitioners to construct inexpensive yet accurate surrogates to be used in place of the expensive forw…
Robust scalable initialization for Bayesian variational inference with multi-modal Laplace approximations
Wyatt Bridgman, Reese Jones, Mohammad Khalil
For predictive modeling relying on Bayesian inversion, fully independent, or ``mean-field'', Gaussian distributions are often used as approximate probability density functions in v…
