get_all_objective_names
()[source]¶ Get a list of the names of all objectives.
- Returns
Objective names
- Return type
list (str)
-
evalml.objectives.utils.
get_core_objective_names
()[source]¶ Get a list of all valid core objectives.
- Returns
Objective names.
- Return type
list[str]

get_core_objectives
(problem_type)[source]¶ Returns all core objective instances associated with the given problem type.
Core objectives are designed to work out-of-the-box for any dataset.
- Parameters
problem_type (str/ProblemTypes) – Type of problem
- Returns
List of ObjectiveBase instances
-
evalml.objectives.utils.
get_non_core_objectives
()[source]¶ Get non-core objective classes.
Non-core objectives are objectives that are domain-specific. Users typically need to configure these objectives before using them in AutoMLSearch.
- Returns
List of ObjectiveBase classes
-
evalml.objectives.utils.
get_objective
(objective, return_instance=False, **kwargs)[source]¶ Returns the Objective class corresponding to a given objective name.
- Parameters
objective (str or ObjectiveBase) – Name or instance of the objective class.
return_instance (bool) – Whether to return an instance of the objective. This only applies if objective is of type str. Note that the instance will be initialized with default arguments.
kwargs (Any) – Any keyword arguments to pass into the objective. Only used when return_instance=True.
- Returns
ObjectiveBase if the parameter objective is of type ObjectiveBase. If objective is instead a valid objective name, function will return the class corresponding to that name. If return_instance is True, an instance of that objective will be returned.
- Raises
TypeError – If objective is None.
TypeError – If objective is not a string and not an instance of ObjectiveBase.
ObjectiveNotFoundError – If input objective is not a valid objective.
ObjectiveCreationError – If objective cannot be created properly.
