Table 5 Mean multi-class classification accuracy on the defined auxiliary target subgroups. Performance metric was evaluated on the validation sets of each respective fold. Values are given by mean ± standard deviation across all folds for training (train), validation (val) as well as for the top 10 ranking features according to the respective ranking scores (train 10, val 10)
