Perrin, an appropriate mathematical framework is derived for new non-asymptotic estimation techniques, which do not necessitate any statistical analysis of the noises corrupting any sensor. Various applications are deduced for multiplicative noises, for the length of the parametric estimation windows, and for burst errors.Computational Engineering, Finance, and ScienceLogicOptimization and ControlProbabilityQuantum Physicstext
