A Reduced Order Modeling Method with Variable-Separation-Based Domain Decomposition for Parametric Dynamical Systems
Yuming Ba, Liang Chen, Yaru Chen +1
This paper proposes a model order reduction method for a class of parametric dynamical systems. Using a temporal Fourier transform, we reformulate these systems into complex-valued…
Weighted RML using ensemble-methods for data assimilation
Yuming Ba, Dean S. Oliver
The weighting of critical-point samples in the weighted randomized maximum likelihood method depend on the magnitude of the data mismatch at the critical points and on the Jacobian…
Randomized maximum likelihood based posterior sampling
Yuming Ba, Jana de Wiljes, Dean S. Oliver +1
Minimization of a stochastic cost function is commonly used for approximate sampling in high-dimensional Bayesian inverse problems with Gaussian prior distributions and multimodal…
Ensemble-based implicit sampling for Bayesian inverse problems with non-Gaussian priors
Yuming Ba, Lijian Jiang
In the paper, we develop an ensemble-based implicit sampling method for Bayesian inverse problems. For Bayesian inference, the iterative ensemble smoother (IES) and implicit sampli…
A two-stage ensemble Kalman filter based on multiscale model reduction for inverse problems in time fractional diffusion-wave equations
Yuming Ba, Lijian Jiang, Na Ou
Ensemble Kalman filter (EnKF) has been widely used in state estimation and parameter estimation for the dynamic system where observational data is obtained sequentially in time. To…
