“…As an unbiased interpolation method, the KG model can fit multi-dimensional and strong non-linear responses well, and it has a high fitting accuracy and fitting error estimation. 22 The basic form of this model and the details of this modeling process can be found in Zeng et al 23 As the sealing performance calculation of the connector sealing structure is high dimensional and strong non-linear problem, a non-linear KG model was constructed to fit the relationship between design variables and sealing performance indexes for the purpose of improving the calculation efficiency. Therefore, in this paper, the ordinary Sobol method and the KG model were combined to establish a new sensitivity analysis method, which can be applied to improve the sensitivity analysis efficiency when determining connector sealing performance.…”

“…This will lead to a strong nonlinear characteristic relationship between the grinding amount and grinding parameters, which results in a decline in the prediction accuracy for the established prediction model, thereby certainly reducing the prediction precision of the final grinding profile. Therefore, the KG model is used to fit the relationship between the grinding area and grinding parameters based on its good ability in nonlinear function estimation in the literature by Yang et al 3 However, KG model is a kind of interpolation model with unbiased estimation, the computational cost is relatively high, particularly the variable dimension greater than or equal to three, the computational cost increases significantly, 18 which after prediction will increase the computation time of completion to nearly 50 min. For the practical grinding operation, the computation time is too long.…”
