A 4D-Var Method with Flow-Dependent Background Covariances for the Shallow-Water Equations
Daniel Paulin, Ajay Jasra, Alexandros Beskos +1
The 4D-Var method for filtering partially observed nonlinear chaotic dynamical systems consists of finding the maximum a-posteriori (MAP) estimator of the initial condition of the…
Efficient sequential Monte Carlo algorithms for integrated population models
Axel Finke, Ruth King, Alexandros Beskos +1
State-space models are commonly used to describe different forms of ecological data. We consider the case of count data with observation errors. For such data the system process is…
Optimization Based Methods for Partially Observed Chaotic Systems
Daniel Paulin, Ajay Jasra, Dan Crisan +1
In this paper we consider filtering and smoothing of partially observed chaotic dynamical systems that are discretely observed, with an additive Gaussian noise in the observation.…
