^aD-based: description-based method.

^bE-based: example-based method.

^cD+E-based: description and example combination-based method.

^dSD: unbiased sample standard deviation.

^eFor the D-based method, there are missing values because 5-fold cross-validation is not utilized as described in the evaluation method section.
