Empty constructor. Builds a new itemset without items. |
|
Constructor given the list of items as TreeSet.
|
|
Adds a new item to this itemset.
Implements kddml.Core.DataMining.AssociationRules.ItemsetManager. |
|
Sets the support of this itemsets. Support must be a number between 0 and 1, inclusive.
Implements kddml.Core.DataMining.AssociationRules.ItemsetManager. |
|
Returns the support ot the itemset in the model as a percentage in respect to the total number of transactions. It is a number between 0 and 1, inclusive. Can be null.
Implements kddml.Core.DataMining.AssociationRules.ItemsetManager. |
|
Returns the support for this itemset in terms of absolute count of transactions supporting it.
Implements kddml.Core.DataMining.AssociationRules.ItemsetManager. |
|
Returns the number of items. Returns a value >=0.
Implements kddml.Core.DataMining.AssociationRules.ItemsetManager. |
|
Returns the list of items as iterator.
Implements kddml.Core.DataMining.AssociationRules.ItemsetManager. |
|
Tests if an item is contained in the itemset.
Implements kddml.Core.DataMining.AssociationRules.ItemsetManager. |
|
Tests if this itemset satisfy an input transaction. A transaction satisfy an itemset I1, ..., In if every item Ii with i in [1, m] occurs in the transaction.
Implements kddml.Core.DataMining.AssociationRules.ItemsetManager. |
|
Tests if two itemsets are equals, i.e., they contains the same items.
Implements kddml.Core.DataMining.AssociationRules.ItemsetManager. |
|
Returns the list of items as transaction.
