We present an efficient particle filtering algorithm for multiscale systems, that is adapted for simple atmospheric dynamics models which are inherently chaotic. Particle filters represent the posteri...
Judging Model Reduction of Chaotic Systems via Optimal Shadowing Criteria
Shadowing Criteria Chaotic Systems
2010/4/2
A common goal in the study of high dimensional and complex system is to model the system by a low order representation. In this letter we propose a general approach for assessing the quality of a redu...
