Researchers have developed a new methodology called AL-SPCE, which uses active learning combined with stochastic polynomial chaos expansions to improve the reliability analysis of nondeterministic models. This approach significantly reduces the computational cost compared to traditional Monte Carlo simulations and previous surrogate-based methods. AL-SPCE identifies regions where the emulator has high predictive uncertainty, leading to more efficient and accurate reliability estimates, as validated across three problem types. AI
