Description

Measuring the expected information gain (EIG) of an experiment allows for comprehensive design optimization. Efficiently estimating the EIG is crucial when data are scarce or costly to obtain. We propose several estimators combining the randomized quasi-Monte Carlo method with Laplace-based importance sampling, and showcase their efficiency both theoretically and via numerical examples.
