Among other criteria for choosing the optimal number of clusters, let us mention BIC (Schwarz Bayesian Criterion) and AIC (Akaike Information Criterion). 3 Association Rule Discovery In principle, by the association rule discovery/association rule learner we understand the process of identifying the rules of dependence between different groups of phenomena. Thus, let us suppose we have a collection of sets each containing a number of objects/items. We aim to find those rules which connect (associate) these objects and so, based on these rules, to be able to predict the occurrence of an object/item, based on occurrences of others.
