Results of four neighborhood-based quality metrics for Banknote data

Results of four neighborhood-based quality metrics for Banknote data: Neighborhood hit (Qh), Trustworthiness (Qt), Continuity (Qc), and Jaccard set distance (Qj). Note that Qh is consistent with results from Figure 3 and best represents the visual cluster separation, whereas Qt, Qc, and Qj suggest the opposite. Note that Qt, Qc, and Qj do not consider class label information. More results including Qt, Qc, and Qj for the five synthetic data sets can be found in the supplemental materials.
