Robust A-Optimal Experimental Design for Bayesian Inverse Problems

no code implementations5 May 2023 Ahmed Attia, Sven Leyffer, Todd Munson

This work presents an efficient algorithmic approach for designing optimal experimental design schemes for Bayesian inverse problems such that the optimal design is robust to misspecification of elements of the inverse problem.

Stochastic Learning Approach to Binary Optimization for Optimal Design of Experiments

no code implementations15 Jan 2021 Ahmed Attia, Sven Leyffer, Todd Munson

We present a novel stochastic approach to binary optimization for optimal experimental design (OED) for Bayesian inverse problems governed by mathematical models such as partial differential equations.

A Machine Learning Approach to Adaptive Covariance Localization

no code implementations2 Jan 2018 Azam Moosavi, Ahmed Attia, Adrian Sandu

In typical weather forecasting applications, the model state space has dimension $10^{9}-10^{12}$, while the ensemble size typically ranges between $30-100$ members.
