Effective Filtering for Multiscale Stochastic Dynamical Systems in Hilbert Spaces

Probability 2019-10-21 v5

Abstract

In the paper, effective filtering for a type of slow-fast data assimilation systems in Hilbert spaces is considered. Firstly, the system is reduced to a system on a random invariant manifold. Secondly, nonlinear filtering of the origin system can be approximated by that of the reduction system. Finally, we apply the obtained result to an example.
