Abstract Grain yield security is a basic national policy of China, and changes in
grain yield are influenced by a variety of factors, which often have a complex,
non-linear relationship with each other. Therefore, this paper proposes a Grey
Relational Analysis–Adaptive Boosting–Support Vector Regression (GRAAdaBoost-SVR) model, which can ensure the prediction accuracy of the model
under small sample, improve the generalization ability, and enhance the prediction
accuracy. SVR allows mapping to high-dimensional spaces using kernel functions,
good for solving nonlinear problems. Grain yield datasets generally have small
sample sizes and many features, making SVR a promising… More >
