Imbalanced Datasets and Crop Yield Prediction: Application of Preprocessing Techniques for Regression Tasks in AgricultureMariaelisa Polsinelli, Morteza Mesbah, Zhiming Qi, and 1 more authorIn 2024 ASABE Annual International Meeting, 2024Machine learning (ML) is increasingly used in the agricultural sector to predict crop yields. The ability to produce short-term seasonal forecasting or future projections is highly important for creating climate change adaptation strategies. The escalation of extreme weather events such as drought due to climate change is a significant threat to crop yields. While ML algorithms like Random Forest (RF) have shown great performance on balanced datasets, the increase in weather extremes presents a challenge as historical data may lack instances of low yield years, leading to unbalanced datasets biased towards ‘normal’ or ‘well performing’ years. Three preprocessing techniques; random undersampling (US), random oversampling (OS), and the Synthetic Oversampling Technique for Regression (SMOTER) were applied to the training datasets of nine industrial farm field-years growing Russet Burbank using RF. Assessing the nine field-years overall, US improved the relative root mean square error (RRMSE) from the baseline the most reducing it from 16.7[PM(1.1]% to 14.1%. Individually, US was the winning technique for five of the nine fields, likely due to a reduction in overfitting. SMOTER provided the largest improvement in performance for Field 3b (drought year). The baseline RRMSE for this field was 36.8% (poor). The application of SMOTER to synthetically increase low yield data points and high GDD low precipitation values in the training dataset reduced the RRMSE to a satisfactory 26.3%. The results indicate that SMOTER, potentially in combination with other performance techniques, can be a viable option for improving the yield prediction of drought and extreme weather years.
