Compute corners and add them to a FeatureSystem or SetSeparationSystem

Parameters

feature_systemSetSeparationSystemBase, FeatureSystem, AdvancedFeatureSystem or SetSeparationSystem

A feature system or separation system

feature_idslist, np.ndarray, range or None

a selection of a subset of feature_system

min_size_fractionfloat

Discard corners with minimum size smaller than min_size_fraction * dataset_size. This parameter can be used to control the balance.

order_funcSetSeparationOrderFunction or None

an order function

max_order_factor: float

Discard corners of two features with an order greater than max_order_factor times the greater order of the two features.

global_max_order: float

Discard corners that have an order greater than this value

Returns

range:

the id range of the added features
