WebThe RF, SVM and PLS methods were applied to classify the five VIs. When the results of the classifications for predicting pasture biomass and producing appropriate maps were compared, the PLSR technique showed the highest accuracy, resulting in R 2 of 0.899 and RMSE of 10.560 g/m 2 . WebThe highest classification accuracies for LS-SVM, PLS-DA, NDVI, RE/R, and PRI were 93.6%, 92.4%, 72.5%, 69.6%, and 58.1%, respectively, without false-positive errors. Among these methods for identifying plant heat stress, the developed LS-SVM and PLS-DA models showed more reliable discriminant performance than the traditional VIs.
