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…
Sensitivity-driven adaptive construction of reduced-space surrogates
Manav Vohra, Alen Alexanderian, Cosmin Safta +1
We develop a systematic approach for surrogate model construction in reduced input parameter spaces. A sparse set of model evaluations in the original input space is used to approx…
