### Abstract

Summary form only given, as follows. Recently, a theory of discrete-time optimal estimation (filtering, smoothing, and prediction) based on convex sets of probability distributions has been developed. By restricting attention to the linear Gaussian problem, a set-valued estimator is obtained; the estimator is an exact solution to the problem of running an infinity of Kalman filters (and fixed-interval smoothers), each with different initial conditions. The philosophical basis underlying the theory of set-valued estimation is presented, and the estimator developed for the linear Gaussian problem is briefly reviewed. A geometrical interpretation of this estimator is presented; this interpretation provides a natural and informative framework in which the set-valued estimator can be understood. In addition, the geometric interpretation leads to a significant generalization in the sets that can be represented in the set-valued estimation algorithms.
