The key that performed best in clustering optimization (thus representing the most appropriate taxonomic concept) was then applied to identify the specimens collected by ZB (for pragmatic reasons, these were not re-identified using the suboptimal keys).
The results illustrated that hierarchical model has the best performance in clustering of AE signals.
For example, clustered genes do not always share the same cis-elements, and selection of the best thresholds in clustering is a difficult issue (Kundaje et al. 2007).
Based on the previous research [17] focused on a comparative study of term weighting schemes, we observed that standard tf-idf achieved the best results in clustering of the Slovak text documents obtained from Wikipedia.
For MCL, we set the inflation factor to 1.8, as this has been found to yield the best performance in clustering biological networks (Brohee and van Helden, 2006).
The other two algorithms (average and maximum) switched back and forth, competing for the best in conjunction with clustering algorithms to group individuals.
Besides, Hathaway and Bezdek [9] defined a gentle objective-based approach for both clustering and incomplete data handling towards the best resulting clusters in an iterative manner.
Cluster 21 from Figure 5 (Seoul Nat Univ. and Univ. Sao Paulo) are now together with other 14 best performing universities in cluster 11 from Figure 7 (Moscow state Univ., Univ. Melbourne, Univ. Sydney, among others).
They look best when they are planted in clusters, groups of five to nine or more.
