Entropy stable conservative flux form neural networks
Lizuo Liu, Tongtong Li, Anne Gelb +1
We propose an entropy-stable conservative flux form neural network (CFN) that integrates classical numerical conservation laws into a data-driven framework using the entropy-stable…

Sampling error mitigation through spectrum smoothing: first experiments with ensemble transform Kalman filters and Lorenz models
Bosu Choi, Yoonsang Lee
In data assimilation, an ensemble provides a way to propagate the probability density of a system described by a nonlinear prediction model. Although a large ensemble size is requi…
