/ > 0g is the set of successfully
created PCWs, which are defined as those whose compatibilities, assessed by our scoring model,
get improved as compared to the original ones.
Table 7.2 shows the PCW creation results of different methods. As can be seen, PCW-DC
achieves the best performance with respect to all metrics, demonstrating the superiority of the
proposed PCW-DC for PCW creation. In addition, methods that overlook both the garments
and user profiles (i.e., POP and RAND) perform worst, while the method that considers the
naive garment interaction (i.e., ISBM) promotes the performance slightly. Comparing with the
above methods, DCF-A and CWC with more advanced compatibility modeling achieve the
better performance. However, due to the limited modeling perspective of each method, DCF-
A and CWC still suffer from the inferior performance than PCW-DC. Moreover, ExDCF-A
outperforms DCF-A, which demonstrates the necessity of incorporating the user modeling to
fulfill the PCW creation. To gain a better understanding, a successful example created by PCW-
DC is shown in Figure 7.4. As can be seen, the somewhat monotonous original wardrobe has
turned to be a versatile wardrobe by adding garments that share the similar style with the original
wardrobe and deleting those hurt the overall wardrobe compatibility. Moreover, we found that
most of the potential outfits of the final PCW are compatible, which meets the initial motivation
of our PCW creation.
