public java.util.Collection<AssociationRule<T>> mineRules(java.util.Collection<java.util.Collection<T>> database, int conclusion_limit, int total_limit)
Description copied from interface:AssociationRuleMiner
Mines a set of association rules from the given database. Only those rules are mined where the conclusion and in total has the maximal given number of elements, respectively.- Parameters:
database
- some databaseconclusion_limit
- the maximal size of elements in the conclusion of the mined rules.total_limit
- the total number of elements that may appear in the mined rules.- Returns:
