saealib.ReferencePointComparisonSet

class saealib.ReferencePointComparisonSet(ref_source='population_best')

ベースクラス: TrainingSet

Binary labels: 1 if archive point dominates the reference point, 0 otherwise.

Unlike PairwiseComparisonSet, train_x has shape (n_archive, dim), making it compatible with GlobalSurrogateManager and LocalSurrogateManager.

パラメータ:

ref_source (str) -- How to select the reference point: - "population_best" (default): best individual in the current population - "archive_best": best individual in the archive

例外:

• ValueError -- If ctx is None (comparator required).

• ValueError -- If ref_source="population_best" and population is None.

Methods

__init__
build	Return binary labels: 1 if archive point dominates reference, 0 otherwise.
contract	Return the training-set contract.
