摘要
A Markovian jump process theta , with finite state space, feeding the parameters of a nonlinear diffusion process X is considered. theta and X are observed in white noise. Given a function f, it is desired to construct a finite filter for the f(X//t)-process. An algorithm is investigated which will produce a finite filter if it halts after a finite number of steps. Necessary and sufficient conditions for this to happen are presented.
