Prediction of pollination stages in oil palm plantations is an important research area in precision *** palm is known as the most efficient commercial crop with the capacity to fulfill the growing global demand for vegetable oil ***,oil palm production dependence on pollination is experiencing issues with decreasing the actual ***,alternative methods in commercial plantations such as humanassisted pollination and recently Wireless Sensor Network(WSN)have been deployed despite their high economic costs due to labor *** palm assisted pollination requires precision,inspection,traceability,and validation processes in the ***,all these processes are performed by humans that can be associated with false assumptions,uncertainty,and pollination ***,Machine Learning(ML)approaches as a subset of the Artificial Intelligence(AI)domain provides efficient,cost-effective,and non-destructive solutions to determine these reproductive stages for future autonomous pollination *** goal was to reduce the variability of worker’s performance in oil palms,using ML algorithms to make expert decisions and reduce the risk related to a transient *** comparative empirical study examined and compared the performance of the Random Forest(RF)against k Nearest Neighbor(kNN)and Support Vector Machine(SVM)for classification of oil palm pre-anthesis and anthesis stages,dividing into four classes(1,2,3,and 4).These models were tested using thermal features(endogenous)individually and in combination with meteorological variables(exogenous).The performance of models is evaluated with specific measures of performance,such as overall user’s and producer’s accuracies and F-measure values derived from the confusion *** results showed that the RF model produced better results with regard to average Fmeasure(88.6%,71.83%),producer’s accuracies(88.70%,71.35%),and user’s accuracies(88.27%,72.36%)on test set
