By Andrew H. Physical systems are designed and built to perform certain defined functions.
In the theory of stochastic processes , the filtering problem is a mathematical model for a number of state estimation problems in signal processing and related fields. The general idea is to establish a "best estimate" for the true value of some system from an incomplete, potentially noisy set of observations on that system.
The problem of optimal non-linear filtering even for the non-stationary case was solved by Ruslan L. Stratonovich , [1] [2] , see also Harold J. Kushner 's work [3] and Moshe Zakai 's, who introduced a simplified dynamics for the unnormalized conditional law of the filter [4] known as Zakai equation.
The solution, however, is infinite-dimensional in the general case. More generally, as the solution is infinite dimensional, it requires finite dimensional approximations to be implemented in a computer with finite memory. A finite dimensional approximated nonlinear filter may be more based on heuristics, such as the Extended Kalman Filter or the Assumed Density Filters, [6] or more methodologically oriented such as for example the Projection Filters, [7] some sub-families of which are shown to coincide with the Assumed Density Filters.
In general, if the separation principle applies, then filtering also arises as part of the solution of an optimal control problem. For example, the Kalman filter is the estimation part of the optimal control solution to the linear-quadratic-Gaussian control problem.
It is assumed that observations H t in R m note that m and n may, in general, be unequal are taken for each time t according to. This elementary result is the basis for the general Fujisaki-Kallianpur-Kunita equation of filtering theory. From Wikipedia, the free encyclopedia.

The object of this course is to lead to a good understanding of stochastic processes, their most commonly used models and their properties, as well as the derivation of some of the most commonly used estimators for such processes : Wiener and Kalman filters, predictors and smoothers. At the end of this learning unit, the student is able to : 1 1.
Scientific Research An Academic Publisher. ABSTRACT: This paper surveys the field of adaptation mechanism design for uncertainty parameter estimation as it has developed over the last four decades. The adaptation mechanism under consideration generally serves two tightly coupled functions: model identification and change point detection. After a brief introduction, the pa-per discusses the generalized principles of adaptation based both on the engineering and statistical literature. The stochastic multiinput multioutput MIMO system under consideration is mathematically described and the problem statement is given, followed by a definition of the active adaptation principle.

And I give him all credit for this attempting to separate signal and noise by a linear filter, although it was. Stochastic processes, for most people working in the area of radar and sensors, are essential to understand how these device measure through filtering theory. The need for this book is twofold.

Although stochastic process theory and its applications have made great progress in recent years, there are still a lot of new and challenging problems existing in the areas of theory, analysis, and application, which cover the fields of stochastic control, Markov chains, renewal process, actuarial science, and so on. These problems merit further study by using more advanced theories and tools. The aim of this special issue is to publish original research articles that reflect the most recent advances in the theory and applications of stochastic processes. The focus will especially be on applications of stochastic processes as key technologies in various research areas, such as Markov chains, renewal theory, control theory, nonlinear theory, queuing theory, risk theory, communication theory engineering and traffic engineering.
