Glass
A forensic dataset describing types of glass. This version is based on a publication by Keller et al. (HiCS, [1]). The authors use the class 6 (minority) as outlier and all other classes as inliers. Unfortunately, they do not detail which attributes have been used. The original dataset consists of 9 attributes, here are only 7 attributes present. The dataset contains 214 instances, 9 outliers (21.4%) and 205 inliers (95.79%). This dataset contains only one duplicate, so we did not create a version without duplicates.

Best Parameters
The following table contains the best
(overall and per-method)
results for each method and evaluation measure (when the same score was achieved twice, only the smallest k is given).
The Maximum F1-Measure is complimentary in addition to the measures in the original publication.
