“…SHAP is based on an approach subject to cooperative game theory [ 20 ], which centers on the introduction of Shapley values to construct an additive explanatory model that facilitates the interpretation of the performance of machine learning models or deep learning models, i.e., Shapley values [ 21 ] measure the marginal contribution of each input variable in the overall cooperation. This approach falls under the category of additive feature attribution, and a surprising property in this category is the existence of a single unique solution that has three desirable properties: local accuracy, missingness, and consistency.…”

“…The SHAP value is used as a unified measure in measuring feature importance. This Shapley value is the value of the conditional expectation function of the original model [100], [101]. Thus, they are solutions to the equation:…”

“…The first aerodynamic problem is the GSA of a subsonic wing to investigate the effect of wing twists on aerodynamic performance [42]. The input variables are the twist angle at eight different sections of an untapered wing with NACA 2412 airfoil, varied from -10 to 10 degrees.…”
