saealib.ManagerSwitcher

class saealib.ManagerSwitcher(primary, fallback, *, metric='spearman', threshold=0.5)

ベースクラス: AccuracyBasedSurrogateSwitcher[SurrogateManager]

Switch between two surrogate managers based on an accuracy threshold.

Returns primary when metric >= threshold, fallback otherwise, including when accuracy is unavailable or the metric is non-finite.

パラメータ:

• primary (SurrogateManager) -- Manager used when accuracy is satisfactory.

• fallback (SurrogateManager) -- Manager used when accuracy is poor or not yet available.

• metric (str) -- Metric key in SurrogateAccuracy. Default: "spearman".

• threshold (float) -- Minimum acceptable metric value. Default: 0.5.

Methods

__init__
contract	Return the manager-switcher contract.
switch	Return primary or fallback based on the metric threshold.
