__init__(target: Target)

Method generated by attrs for class SingleTargetObjective.

For details on the parameters, see Public attributes and properties.

classmethod from_dict(dictionary: dict)

Create an object from its dictionary representation.

Parameters:

dictionary (dict) – The dictionary representation.

Return type:

TypeVar(_T)

Returns:

The reconstructed object.

classmethod from_json(string: str)

Create an object from its JSON representation.

Parameters:

string (str) – The JSON representation of the object.

Return type:

TypeVar(_T)

Returns:

The reconstructed object.

to_dict()

Create an object’s dictionary representation.

Return type:

dict

to_json()

Create an object’s JSON representation.

Return type:

str

Returns:

The JSON representation as a string.

transform(df: DataFrame | None = None, /, *, allow_missing: bool = False, allow_extra: bool | None = None, data: DataFrame | None = None)

Transform target values from experimental to computational representation.

Parameters:

• df (Optional[DataFrame]) – The dataframe to be transformed. The allowed columns of the dataframe are dictated by the allow_missing and allow_extra flags.

• allow_missing (bool) – If False, each target of the objective must have exactly one corresponding column in the given dataframe. If True, the dataframe may contain only a subset of target columns.

• allow_extra (Optional[bool]) – If False, each column present in the dataframe must correspond to exactly one target of the objective. If True, the dataframe may contain additional non-target-related columns, which will be ignored.

Return type:

DataFrame

Returns:

A corresponding dataframe with the targets in computational representation.
