For research tasks 3 and 4: Mean, median, and standard deviation (over 50 samplings of discovery/validation data) of the difference (both unscaled and scaled) between the value of the evaluation criterion on the validation data and the corresponding value on the discovery data.

Additionally, the effect size (mean divided by standard deviation) is reported. GCDdiscov denotes the largest GCD on the discovery data and GCDvalid the GCD resulting from the corresponding method combination on the validation data. The quantities ASWdiscov, ASWvalid (average silhouette width) are defined analogously.
