public class PropositionalToMultiInstance
extends Filter
implements OptionHandler, UnsupervisedFilter
Converts a propositional dataset into a multi-instance dataset (with relational attribute). When normalizing or standardizing a multi-instance dataset, the MultiInstanceToPropositional filter can be applied first to convert the multi-instance dataset into a propositional instance dataset. After normalization or standardization, we may use this PropositionalToMultiInstance filter to convert the data back to multi-instance format.
Note: the first attribute of the original propositional instance dataset must be a nominal attribute which is expected to be the bagId attribute. Valid options are:
Note: the first attribute of the original propositional instance dataset must be a nominal attribute which is expected to be the bagId attribute. Valid options are:
-no-weights Do not weight bags by number of instances they contain. (default off)
-S <num> The seed for the randomization of the order of bags. (default 1)
-R Randomizes the order of the produced bags after the generation. (default off)
