The nonlinear filter problem can be classified as an inverse problem of identifying the state of a system with noise perturbation given observations of the system, also perturbed by noises.  Traditional numerical simulation methods include unscented Kalman filter and particle filter.  In this talk, I will talk about some new efficient construct efficient numerical methods based on forward backward stochastic differential equations and implicit function theory.  Numerical experiments will be presented to demonstrate that our methods are more accurate than Kalman filter and more stable than the particle filter.
