The impact of model dimensionality. a Performance on the held-out test set across Gradient Boosting Machine-based models incorporating features recursively eliminated in order of Gini-importance from the full model. Note that full performance is reached only after the inclusion of 81 features. b Gini-importance based ranking of the features in the best Gradient Boosting Machine model; the top 8 are labelled. Note the wide distribution of feature importance across variables
