Clustering is descriptive or predictive
WebClustering, summarization, association are the techniques categorized under descriptive mining. Definition of Predictive Data Mining. The primary objective of predictive mining is to predict future results instead of current behaviour. It involves the supervised learning functions used for the prediction of the target value. Web5. Hierarchical Clustering. Hierarchical cluster analysis is a model that creates the hierarchy of clusters. Beginning with all the data points allocated to their respective cluster, the method combines the two closest clusters into the common one. At last, the algorithm will only stop when only one cluster is left.
