FIGURE 9

The estimate values of (A) Matthews correlation coefficient (MCC), (B) Precision, (C) Recall, and (D) F-Measure for RF, MLP, SVM, and the E–S algorithms used for predicting soybean yield from all and selected variables collected (-VS) at the R5 growth stage. The mean performance is indicated with × in each figure. MLP, multilayer perceptron; SVM, support vector machine; RF, random forest; E–S, ensemble–stacking strategy; RFE, recursive feature elimination.
