UnverifiedThis study proposes a survey-weighting framework based on hierarchical Gaussian process (HGP) regression, using kernel smoothing to share information across related units, and derives local equivalent weights.77% similarUnverifiedSimulation experiments compared the performance of HGP and logistic regression: under nonparametric structures, HGP achieved lower population-weighted prediction error; while when the parametric model was correctly specified, logistic regression performed well.76% similarUnverifiedH-GBP provides a rigorous convergence proof by deriving the combined matrix operator of the abstraction and recovery steps and analyzing its spectral radius to prove convergence to the optimal solution.67% similarUnverified生成模型在小样本时更具优势，判别模型在大数据量时通常表现更好67% similarUnverifiedXGBoost等集成模型预测性能更强但天然是黑箱，配合SHAP分析可弥补可解释性短板67% similar
