Filtering dynamical systems using observations of statistics
We consider the problem of filtering dynamical systems, possibly stochastic, using
observations of statistics. Thus, the computational task is to estimate a time-evolving density …

Probabilistic data-driven turbulence closure modeling by assimilating statistics
S Ephrati - arxiv preprint arxiv:2408.14838, 2024 - arxiv.org
A framework for deriving probabilistic data-driven closure models is proposed for coarse-
grained numerical simulations of turbulence in statistically stationary state. The approach …
