Fig. 3

Simplified illustration of the decision made by the ANN model. The regression trees were trained to predict the output probabilities made by the ANN model, given the identified top-ranked variables. Each tree was only allowed to grow to depth 4 and the full dataset was used to construct the trees. The numbers in the green boxes indicate average ANN output and the size of the data at the given node. A Decision tree N0 vs. N+; B Decision tree N1 vs. N0; C Decision tree N2 vs. N0 and N1
