Fig. 4From: Application of machine learning techniques to simulate the evaporative fraction and its relationship with environmental variables in corn cropsComparison between observed and predicted daily EF, during the training phase, of the four different approaches: SVM polynomial model (A), GRP rational quadratic (B), GRP Matern 5/2 (C), and SVM cubic Gaussian (D). Colored circles represent the observed values, black circles the predicted values, and the dashed lines represent the 95% confidence intervalBack to article page
