报告简介:Uncertainty quantification (UQ), in its broadest sense, is the science of identifying, characterizing, and managing uncertainties in both computational models and real-world systems. Forward UQ is a key branch that examines how input uncertainties influence model outputs, with significant applications in applied sciences and engineering. This talk will address forward UQ from a Bayesian active learning perspective, with a focus on time-independent, time-dependent and dynamic reliability analysis, as well as response probability distribution estimation. The core idea is to treat the quantities of interest as Bayesian inference problems and then use the resulting posterior statistics to design the key components of active learning—such as stopping criteria and learning functions. Numerical examples show that these methods can significantly improve computational efficiency while maintaining desired accuracy.
