The clustering analysis is feasible only when the groups are formed with important features. The existing K-Means clustering processing time and the computation cost is high. The proposed two level variable wei
two-way clusteringcross validationMultiple correspondence analysis (MCA) is a useful tool for investigating the interrelationships among dummy-coded categorical variables. MCA has been combined with clustering methods to examine whether there exist heterogeneous subclusters of a population, which exhibit ...
This clustering algorithm is generally suitable for the datasets with spherical-shaped clusters and is not suitable for the complex datasets. Maione et al. have presented a cluster analysis using the PAM clustering algorithm [60] for social data that is capable of handling variables of mixed types...
Without a strong effort to do so, cluster analysis would remain a black art accessible only to those true believers with great experience and confidence. Clustering is an unsupervised learning technique, so it is difficult to assess the output quality of any given technique. If we use ...

Results are easier to interpret with fewer analysis fields. It is also easier to determine which variables are the best discriminators when there are fewer fields. Sometimes you know the Number of Clusters most appropriate for your data. If you don't, however, you may have to try dif...
