Filtering problem (stochastic processes): The mathematical formalism, Overview & More advanced result: nonlinear filtering SPDE

In the theory of stochastic processes, filtering describes the problem of determining the state of a system from an incomplete and potentially noisy set of observations. For example, in GPS navigation, filtering helps estimate a car’s true position (the state) from noisy satellite signals (the observations). While originally motivated by problems in…
