Laplace method is a widely used method to approximate an integration in statistics. We analyze this method in the context of optimal Bayesian experimental design and extend this method from the classical scenario, where parameters can be completely determined by the experiment, to the scenarios where an unidentifiable parametric manifold exists. We show that by carrying out this approximation the estimation of the expected Kullback-Leibler divergence can be significantly accelerated. The developed methodology has been applied to the optimal experimental design of impedance tomography and seismic source inversion.
