deephyper.problem.ForbiddenLessThanRelation#

class deephyper.problem.ForbiddenLessThanRelation#

Bases: ConfigSpace.forbidden.ForbiddenRelation

A ForbiddenLessThan relation between two hyperparameters.

The ForbiddenLessThan compares the values of two hyperparameters.

>>> from ConfigSpace import ConfigurationSpace, ForbiddenLessThanRelation
>>>
>>> cs = ConfigurationSpace({"a": [1, 2, 3], "b": [2, 5, 6]})
>>>
>>> forbidden_clause = ForbiddenLessThanRelation(cs['a'], cs['b'])
>>> cs.add_forbidden_clause(forbidden_clause)
Forbidden: a < b

Note

If the values of the both hyperparameters are not comparible (e.g. comparing int and str), a TypeError is raised. For OrdinalHyperparameters the actual values are used for comparison not their ordinal value.

Parameters

left (Hyperparameters) – left side of the comparison
right (Hyperparameters) – right side of the comparison
