- For comparison with the Matlab implementation, pre-generated folds are used during cross-validation (three folds read in from csv) - For new validations, we want to use any type of cross-validation (f.e. 5-folds, determined on-the-fly) - The folds are made based on source/weapon-level (so not based on comparison scores) - Keep in mind: not all possible comparisons are present in all datasets
