Researchers have developed a new Bayesian experimental design framework to improve the accuracy and efficiency of estimating information gain in complex physical systems. The proposed method utilizes a grouped geometric pooled posterior approach, partitioning samples into groups to construct more aligned proposals. This technique, implemented via an ensemble Kalman inversion formulation, avoids additional computational costs while enhancing the stability and accuracy of estimators. The framework was evaluated on calibration problems involving Gaussian-linear and network-based models. AI
