A Systematic Review of Spatial Epidemiological Modeling Approaches Applied During the COVID-19 Pandemic Open
Background A wide range of epidemiological modeling approaches have been applied to the SARS-CoV-2 pan-demic, which presents an opportunity to assess common approaches applied to specific research questions. Spatial models interrogate how …

Accelerating Point-Based Value Iteration via Active Sampling of Belief Points and Gaussian Process Regression Open
Partially Observable Markov Decision Processes (POMDPs) are fundamental to decision-making under uncertainty. We introduce a novel scalable approach to accelerate upper bound estimation in Point-Based Value Iteration (PBVI) algorithms, the…

An inaugural forum on epidemiological modeling for public health stakeholders in Arizona Open
Epidemiological models—which help us understand and forecast the spread of infectious disease—can be valuable tools for public health. However, barriers exist that can make it difficult to employ epidemiological models routinely within the…

Statistical characterization of patient response to offered access delays using healthcare transactional data Open
We present a novel framework to characterize the probability that an offered appointment with k ‐days' access delay will be booked and subsequently attended by a patient. We refer to this probability as the “probability of realization” of …
