“…This active learning process relies on a merit function that quantifies the expected merit of choosing each of the MC samples as the next simulation point. AK-SYSi is an improved version of AK-SYS specifically for the composite criterion approach by proposing a refined learning function to avoid false identification of min=max failure modes (Yun et al 2019). Hu et al (2017) proposed the efficient kriging surrogate modeling approach (EKSA) for SSR analysis by using a composite surrogate built upon individual component and singular value decomposition (SVD) to efficiently represent the high-dimensional correlated vectors (Palmer et al 2012).…”

“…Because y 3 ( X ) has no contribution to system failure, new added training points should be as few as possible. We perform the reliability and sensitivity by ALK-TCR method combined with different learning functions, as well as AK-SYSi (Yun et al , 2019) method to compare the efficiency of the proposed method. The added training points of ALK-TCR-U (learning function is U function), ALK-TCR-ERF (learning function is ERF), ALK-TCR-EFF (learning function is EFF), AK-SYSi are shown in Figure 3(a)–3(d), and the initial training samples are same.…”

“…ALK model combining with an adaptive size of candidate points is proposed by Yang et al (2019). Yun et al (2019) proposed an improved AK-SYS by using a refined U learning function. Wei et al (2018) proposed an active learning procedure, which can efficiently and adaptively produce surrogate models for the failure surfaces of systems.…”

“…Therefore, in order to improve the computational efficiency and to avoid a large of simulation cost in engineering reliability analysis, more recent attention has focused on surrogate model-based method, which aims to replace original performance function with approximate numerical model. Up to now, various surrogate models are widely used to balance accuracy and efficiency, such as response surface method (RSM), 17,18 neural network (NN), 19 radial basis function (RBF), 20,21 support vector machine (SVM), 22,23 Kriging model, 2428 polynomial chaos expansion (PCE), 29 polynomial chaos kriging (PCK), 30 and deep neural network (DNN), 31 etc. Generally, to construct a surrogate model, one-shot sampling and sequential sampling are two typical methods.…”
