Scalable, Likelihood-Free Calibration of Ice-Sheet Models with Deep Diffusion Emulators and Feature Matching
Kanghyun Wi, Jaewoo Park, Saumya Bhatnagar +1
The Antarctic ice sheet is a major source of uncertainty in future sea-level projections, and physical simulators such as the PSU3D-ICE model are essential for studying its evoluti…
An adaptive split-combine Gaussian mixture filter for nonlinear and multimodal state estimation
San Kim, Won Chang, Daniel B. Forger +1
Filtering combines model predictions with measurements to estimate the probability density function (PDF) of a system state over time. The PDF often becomes highly asymmetric and e…
Rethinking Forward Processes for Score-Based Nonlinear Data Assimilation in High Dimensions
Eunbi Yoon, Won Chang, Donghan Kim +1
Data assimilation is the process of estimating the state of a dynamical system over time by combining model predictions with measurements. This task becomes challenging when the sy…
