Confusion matrices from each modeling approach. Confusion matrices were generated using the test partitions for each spatial-holdout cross-validation. Circle size is scaled by the number of lakes falling within each category. Trophic states for model predictions and reference data correspond to the acronyms “dys” for “dystrophic”, “eu/mixo” for “eutrophic/mixotrophic”, and “oligo” for “oligotrophic”. Model acronyms are located as the title for each confusion matrix, where “MLP” signifies “Multilayer Perceptron”, “XGB” signifies “Gradient Boosted Regression”, and “Logit” signifies “Multinomial Logistic Regression”.
