Fig. 12From: Analysis of plot-level volume increment models developed from machine learning methods applied to an uneven-aged mixed forestObserved net annual volume increment (m3 ha−1 year−1) as function of basal area (m2 ha−1) and fitted curves that depict the relationship between these two variables using least squares regression (REG), artificial neural network (ANN), support vector machine (SVM), random forest (RF), and nearest neighbor algorithm (kNN)Back to article page
