State space models are widely used in many applications. Estimating the unknown state based on the available measurements is an important and a well studied subject in the literature. Depending on the nature of the problem, these models could involve simple linear equations or complex nonlinearities. Filtering is a general statistical approach for estimating the evolving unknown states from the noisy measurements.
In this report, we consider the hidden Markov model, where inference is tractable conditional on the history of the state of the hidden component. We will take an overview to several filtering algorithms by theoretical derivation and coding implementation and apply them to linear gaussian and nonlinear and non-Gaussian cases.
