Abstract
The information theoretic approach to optimal design of experiments yields a simple design criterion: the optimal design minimizes the expected posterior entropy of the parameters. Unfortunately, this strategy is often computational infeasible for non-linear problems and numerical approximations are required. This paper reviews the information theoretic approach to design of experiments, and examines computational issues related to the minimization of the expected posterior entropy and its asymptotic approximations. It is shown that Maximum Entropy Sampling simplifies both the formulation of the design criterion and the optimization problem. Numerical advantages are shown in an example, where the exact solution is compared to asymptotic optimal solution.
