Abstract

En 中文

• BBD-vertex-Sobol sampling can train high-precision HRE prediction model with minimal samples. • LnN transformation enhances the accuracy of high-nonlinearity nitrogen oxide prediction models. • To achieve high ITE in HRE, lean-burn conditions must ensure that L_IT occurs prior to T_IT.
